The information contained in this manual is subject to change without notice.1GeneralDevices of the series PowerXL™ DC1…E1 are variable frequency drives for the supply of three phase motors. By default they are configured in a way, that induction motors of the respective power class can be supplied without changing the settings. The connection of permanent magnet motors (PM Motors) and Brushless DC Motors (BLDC Motors) is also possible, but requires the selection of the respective Motor Control Mode and an adaptation of some parameters.Devices of the series DC1…E1control PM motors and BLDC motors in …open loop“ without feedback by a speed sensor. Compared to induction motors they are mainly used because of the smaller frame size and an increased efficiency. The applications are similar to the ones with induction motors, but with increased dynamics. The series DC1…E1 is NOT intended to be used in servo applications with PM- and BLDC motors and therefore DC1…E1 doesn’t have functionalities like positioning …..In this Application Note the following aspects are covered:∙Selection of the motor control mode∙Adaptation to the connected motor∙Optimization of the application∙Trouble shooting∙Example: PM-Motor settingsSome required parameters are inside level 3. This level has to be activated by prompting the pass-word into P-14 (Password). The password is 201 by default.See also: AP040052EN “Access to Parameter Level 2 + 3 – Parameter lock –Load Default”.This Application Note presumes that the user is familiar with vector control of induction motors and the setting of the respective parameters, as well as with the optimization of speed control loops.2Selection of the Motor Control ModePM motors and BLDC motors require a different control algorithm compared to induction motors, for which the default settings are intended. A selection is done via parameter P-60.NOTE: The difference between PM motors and BLDC motors is mainly the wave form of the induced voltage (Back EMF). The control modes of DC1…E1 are optimized for that. On the market ther e is no clear differentiation between the two types of motors and sometimes one can find BLDC motors which are named as PM motors or PM motors with a similar induced voltage as a BLDC motor. In case of a bumpy run in the control mode for PM motors (P-60 = 2) sometimes an improvement can be achieved by selecting the control mode for BLDC motors (P-60 = 3).2.1Motor Control Mode (P-60)This parameter adapts the device to the type of the connected motor and determines the way of control. The information given in this Application Note are valid for PM motors and BLDC motors only and refer to the settings P-60 = 2 and 3.Information for the control of induction motors (P-60 = 0 and 1): see Application Note AP040049EN.3Setting Motor DataBefore switching on the motor, the motor data according the name plate or the data sheet have to be prompted and a motor identification run has to be performed.3.1Motor Nom Voltage (P-07)This parameter has to be set to the value of the induced voltage (back EMF) at rated speed. This volt-age is the voltage between two phases. In case the manufacturer states the value between phase and neutral, it has to be multiplied by √3.Inside the documentation of the motor manufacturers one can find the required information in dif-ferent formats.∙as a voltage value ( sometimes called “rated voltage”)∙as a voltage constant (induced voltage at a certain speed, mostly 1000 rpm). In this case the volt-age at the required speed has to be calculated.Example:∙voltage constant = 50 V / 1000 rpm∙required speed = 3000 rpmP-07=50 V1000 rpm∙ 3000 rpm= 150 VeNote: the voltage given by the motor manufacturers can have different meanings:∙The voltage induced at rated speed (Back-EMF). In this case this value has to be prompted.∙The voltage which is present at rated speed and rated torque. This value is higher than the in-duced voltage. It can possibly lead to a situation where the motor takes more current respec-tively runs bumpy. What are the possibilities to determine the right value?o Run motor at rated speed and switch off. Take an oscilloscope and measure the in-duced voltage directly after switch off.3.2Motor Nom Current (P-08)Rated current of the motor. By default, parameter P-08 …Motor Nom Current“ is set to the rated cu r-rent I e of the variable frequency drive. P-08 is also used to set the thermal protection for the motor. In case the rated current of the motor is different to the one of the variable frequency drive, P-08 has to be set accordingly to provide a thermal motor protection.e3.3I-CurrentLimit (P-63)The nominal current of the motor (P-08) can be exceeded for a certain time to provide additional torque during acceleration. In default it is 150 % of the rated current for 60 s within 10 minutes or the equivalent.The maximum value can be set with P-63. This setting has no influence on the motor protection and determines only the max. possible current.This function is of help in cases, where high inertias are accelerated. From experience this can some-times lead to trips because of overcurrent, in cases where the max. current and the hardware trip threshold of the device are too close.3.4Motor Nom Frequency (P-09)Frequency which is necessary for the required speed of the motor. Mostly it can be found as “rated frequency” on the motor name plate or in a data sheet. In case the frequency is not known, it can be calculated out of speed and number of poles p.P-09 [Hz]=n [rpm] ∙p2 ∙60 s/minNOTE: A change of P-09 affects the following parameter settings:3.5Motor Nom Speed (P-10)Motor rated speed in rpm. This is the speed at the frequency set with P-09.NOTE: A change of P-09 “Motor Nom Frequency” will set P-10 to 0!3.6 Switching Frequency (P-17)Switching frequency of the power section. With PM motors and BLDC motors a minimum switching frequency of 16 kHz is recommended. Setting the switching frequency is always a compromise be-tween a smooth run of the motor at higher values and resulting additional losses at the same time. At values above 16 kHz it has to be noted, that DC1…E1 possibly has to be derated and in some cases a device with the next higher rating has to be used.3.7 Motor Identification (P-61)A motor identification run MUST be performe d when using a device of the DC1…E1 series together with a PM motor or a BLDC motor (P-60 = 2 or 3). It sets the parameters automatically, which are necessaryfor an optimal performance. After the motor identification run the drive is ready to be used. Further optimization, see below.The motor identification run determines the values of the following parameters∙ Motor Stator Resistance (P-64)∙ Motor Stator Inductance d-axis (P-65) ∙ Motor Stator Inductance q-axis (P-66)The respective values can also be prompted manually, in case they are available from the motor manufacturer. It is recommended to rely on the motor identification run, because it gives very accu-rate values and ensures optimal performance.A motor identification run is performed during stand still. The internal motor model uses the results for an optimal control of the connected motor.Procedure:∙ Real Time Edit Mode of a DrivesConnect Software, which is possibly connected to the drive, hasto be deactivated. Better: Unplug the connection at the RJ45 jack when performing a motor iden-tification run.∙ DC1…E1 must not be enabled (no START signal) ∙ Select parameter P-62 ∙ Press OK∙ is displayed ∙ Change value to∙ Acknowledge with OK The identification starts automatically, display: resp. Auto-tuning (OLED-display)∙ After the identification the value will automatically be reset to zero. Display: ∙ The device has determined the required parameters.HINT: The motor identification run has ALWAYS to be performed at the device itself. It is NOT possi-ble to activate it through the parameter software DrivesConnect. The motor parameters P-07, P-08and P-09 have to be set before starting the motor identification.4 Optimization4.1 Motor performance at low speedNormally PM motors and BLDC motors can be used in a speed range of 20:1. The series DC1…E1 has a boost function, which increases the torque in the lower range resulting in an improved start behavior and true running in the lower speed range.In case …Motor Control Mode“ P -60 = 2 (PM motors) or P-60 = 3 (BLDC motors), a current, which is injected into the motor, can be set with P-11. The amount of current is calculated as follows:I Boost = 4 ∙ P-11 ∙ P -084.2 Optimization of the speed controllerThe control of PM motors and BLDC motors is based on vector algorithms and the speed loop can be optimized. The factory settings are intended for induction motors. PM motors and BLDC motors al-low higher gains and therefore shorter response times and improved behavior.Parameter P-62 …MSC Gain“ affects the proportional gainof the speed controller as well as the inte-gral one. Changes should be done step by step, while observing their impact to the system behavior. Increasing the value leads to a stronger reaction and consequently to a reduction of the response time. Too high values of P-62 can lead to an instability of the system.5Faults and possible root causesGeneral fault messages and their root causes are described in the user manual for the drives series DC1…E1. The faults listed below are especially related to the use of PM motors and BLDC motors.6Example how to set motor parametersExcerpt from a data sheet of a PM motor manufacturer:Settings of motor parameters:∙P-07 = KE ∙ n N = 64,2 V / 1000 rpm ∙ 3600 r/min = 231 V*∙P-08 = 7.5 A∙P-09 = 240 Hz∙P-10 = 3600 r/minFurther important settings∙Enable menu level 3 (Prompt value defined by P-37 + 100 into P-14. Default: 201)∙The switching frequency (P-17) has to be at least 16 kHz∙Select motor control mode with P-60 (in this example: 2 PM motor with speed regulation) ∙Perform motor identification run with P-61∙Optimize motor performance at start and low speeds (P-11).∙Optimize speed controller, if necessary。

To reduce potential of electric shock, disconnect all power sources before initiating any maintenance of repairs. Keep hands and foreign objects away from ventilation and other openings. Keep air passages clear.INSTALLATIONAs with all electronic equipment, the enclosure should not be mounted in direct sunlight or exposed to other high level heat radiation from a furnace or other source. If it is necessary to mount the controller near such a heat source, a shield may be used to deflect the heat. It is essential that air movement around the controller be unrestricted and nothing should be left lying on the controller as this would interfere with heat transfer to the air.THE NATIONAL ELECTRIC CODE REQUIRES A SEPARATE FUSED DISCONNECTOR CIRCUIT BREAKER BE INSTALLED IN THE INCOMING AC POWER LINE TOTHE CONTROLLER. (See Controller Rating Table)The table gives AC line voltages, line amperes, DC armature output amps, and maximum field output amps for various motor HP ratings. The AC line amperes (RMS) should be used in sizing the wire forboth the armature output and the AC line input connections. The field current is less than (1) one ampere for each of the motors listed and wire for field connections can be sized accordingly. GROUNDINGIt is imperative that the controller frame be connected to building ground for the safety of the operating personnel.WARNINGAC POWER MUST BE DISCONNECTED FROM THE DRIVE CABINET TO ELIMINATE THE HAZARD OF ELECTRICAL SHOCK BEFORE IT IS SAFE TO TOUCH ANY OF THE INTERNAL PARTS OF THE DRIVE. CIRCUITS MAY BE AT LINE POTENTIAL WHETHER THE ENCLOSED DRIVE IS OPEN OR CLOSED. USE EXTREME CAUTION.The controller has been thoroughly tested at the factory to insure proper operation when installed in accordance with the following installation instructions and diagrams.INSERT - WARNINGThe Model 282 is a non-isolated drive. In other words, the common of the controller (pin 4 of TB1) is connected to the power section. (See Fig.) If the common of the controller is connected to earth ground without an isolation transformer, there will be a direct short circuit from the line to earth ground, resulting in damage to the controller. If the common must be connected to earth ground, an isolation transformer is required. (The secondary of the transformer must not be referenced to earth ground.) Also, the common of one controller should not be connected to the common of other controllers unless each one has an isolation transformer. If isolation is required, Introl can provide an isolation board (part number 241-22CH) to be mounted on the Model 282.SET-UP PROCEDURESELECT MODE OF CONTROLa. Speed - If potentiometer is to control speed, jumper 3 to Pin 9 on TB1 or connect tachometerfeedback to Pin 4 & 9. (Diag. 282)b. Torque - If potentiometer is to control torque, connect jumper from "A" to "D" on the top PCboard and disconnect jumper 3 from 9 on TB1.DETERMINE OPERATING VOLTAGEa. For 115 VAC input and 0-90 VDC output, place jumper on transformer "A" to "D" and "B" to"E".b. For 230 VAC input and 0-180 VDC output, place jumper on transformer "A" to "C" and "B" to"C". Select Current Limit Level.SELECT CURRENT LIMIT LEVELa. Refer to the motor nameplate for DC Armature volts and HP rating. Monitor current limitpotentiometer for maximum 150% F.L. motor current. Full counter-clockwise equalsapproximately 17 amps, and full clockwise equals 3 amps.Install any applicable kits as detailed in kit instructions. Control may now be mounted in itsdesignated area. On chassis mounted units, connect operating devices as shown oninterconnection diagrams at back of manual.CHECK MOTOR AND MOTOR NAMEPLATEa. If motor has a thermal overload, connect as shown on interconnection diagrams at back of thismanual. NOTE - Motor thermal connections are often labeled P1 and P2.b. It the motor has a field winding, connect as shown on interconnect diagrams to control fieldterminals. (With a 115 AC supply, the field output will be fixed at 100 VDC; at 230 VAC thefield output will be 200 VDC.) Some motors have dual fields 150-100 VDC and 100/200 VDC.) Care should be taken to insure the correct voltage is connected.c. If the motor has a permanent magnet field, no field connections need be made. INSTALLATION CHECKSPrior to making the AC input line connections, follow these checks using a volt-ohm-meter. WARNING - Do not use a vacuum tube voltmeter or other similar type of meter that has to be powered with AC power.NOTE - With the red as the positive lead, make the following check:Red + Black - Range of Acceptable ReadingsA2 Al 1-4 OhmsF2 F1 100-700 OhmsFl, F2, Al, A2 GND InfiniteIf any of the checks are not within the indicated range, verify all connections and then recheck.Use of an isolation transformer to reduce the possibilities of ground paths is a recommended safety practice. Pin 4 of TB1 can then be connected to earth ground. (ONLY WITH ISOLATION TRANSFORMER)DISCONNECTING MEANSA fused AC line disconnect or circuit breaker is required by the National Electrical Code (NEC). This AC line disconnect or circuit breaker must be installed ahead of the controller.Transformer ProgrammingFor 115 VAC operation -Jumper A-D, B-EFor 230 VAC operation -Jumper A-C, B-CTorque or Current Mode -When operating in the torque mode the current range from 0 to 100% can be selected by adjustment of the speed/torque pot.OPERATION INSTRUCTIONSMAXIMUM SPEED ADJUSTMENTa. Connect motor to the load and allow at least 15 min. warm up before adjusting.b. With the drive running, set the operator's SPEED POT FOR MAXIMUM SPEED POSITION.c. Maximum speed has been preset. Should you wish to raise or lower this setting, adjust theSPEED pot on the printed circuit board. Maximum speed may be increased to approximately15% over motor nameplate base speed of reduced to approximately 70% of motor nameplatebase speed. DO NOT EXCEED MOTOR NAMEPLATE MAXIMUM SPEED RATING.d. Using a hand held tachometer or by visually observing the machine operation, adjust control tothe desired maximum setting.I. R. COMP. ADJUSTMENTThis adjustment is provided to overcome the motor's natural tendency to slow down with increasing load. If improved speed or load characteristics are required by the application, the I.R. Comp. pot can be advanced clockwise to reduce the motor's tendency to slow down. NOTE - If this control is advancedtoo far, the motor speed will tend to oscillate or hunt. If this condition occurs, re-adjust the I.R. Comp adjustment counter-clockwise until motor speed stabilizes without oscillating.SPEED ADJUSTMENTSa. S ee enclosed schematic for different reference pot hook-up configurations.b. Regenerative braking - Lowering the speed reference pot to a lower set-ting will result in brakingaction.
