Parameter DescriptionsPULSE ENC VOLTSPREF: 71.01 Default: 10.0 V Range: 10.0 to 20.0 V Set this approximately to the supply voltage required by the pulse encoder.SINCOS ENC VOLTS PREF: 71.22Default: 5.0 V Range: See below Set the supply volts required by the sin/cos encoder. Enumerated Value : SinCos Encoder Volts0 : 5V 1 : 10VENCODER LINESPREF: 71.02 Default: 2048 Range: 250 to 262143 Set the number of lines to match the type of encoder being used. Incorrect setting of this parameter will result in an erroneous speed measurement.ENCODER INVERTPREF: 71.03 Default: FALSE Range: FALSE/TRUE Used to match the encoder direction to the motor direction. When TRUE, changes the sign of the measured speed and the direction of the position count. Setting the encoder direction should be done as part of the Autotune when running in Closed-loop Vector Mode.LOAD G'BOX RATIO PREF: 71.05Default: 1 Range: 1 to 64 This parameter can be used to configure absolute position control applications. It must be aninteger gear box ratio, e.g. 64:1. If there is a gearbox between the motor and the load, set the gearbox ratio via this parameter. “LOAD POSITION” i.e. the position of the load on the other side of the gearbox, will then be calculated.ENCODER MECHO/SPREF: 71.06 Default: 0.0000 deg Range: 0.0000 to 360.0000 deg (encoder mechanical offset)Use this parameter ro enter a mechanical offset of between 0 and 360 degrees to allow the output shaft position to be correctly zeroed. This value is subtracted from the LOAD POSITION which is reported by the encoder.To zero the shaft position: turn the shaft to the zero position; note the value of the LOAD POSITION parameter, and enter this value into the ENCODER MECH O/S parameter. LOAD POSITION will now read zero.Note that “load position” refers here to the shaft position on the other side of a gearbox which may be mounted on the motor output. It does not refer to the motor shaft position, unless the output gearbox ratio (LOAD G'BOX RATIO) is set to 1 (i.e. no gearbox fitted).ENCODER FBK %PREF: 71.08 Default: —.xx % Range: —.xx % This parameter shows the mechanical speed of the motor shaft, calculated from the encoderfeedback, as a percentage of the user maximum speed setting (MAX SPEED in the REFERENCE function block).SHAFT POSITIONPREF: 71.09Default: —.xx degRange: —.xx degThis diagnostic provides the motor shaft position (before the gear box).Ignore the setting for this parameter78902/EQ HTTL Speed Feedback OptionParameter DescriptionsLOAD POSITIONPREF: 71.10 Default: —.xx degRange: —.xx degThis is the position of a shaft on the other side of a gearbox attached to the motor. If a gearboxis not fitted, set LOAD G'BOX RATIO to 1. This variable is controlled by the position loop, i.e. the position loop will force the load position to equal the demanded position.ENCODER TYPEPREF: 71.04 Default: 0 Range: See below This parameter defines the type of encoder being used.A wrt /AB wrt /BQuadrature and Quadrature Diffdirection = forward direction = reverse(assumes ENCODER INVERT is FALSE)A wrt /AB wrt /BClock/Dir and Clock/Dir Diffdirection = forward direction = reverse(assumes ENCODER INVERT is FALSE)A wrt /AB wrt /B Clock and Clock Diffdirection = forward (assumes ENCODER INVERT is FALSE)direction = forward(ignored)Enumerated Value : Type0 : QUADRATURE single-ended pulse encoder 1 : CLOCK/DIR single-ended pulse encoder 2 : CLOCK single-ended pulse encoder 3 : QUADRATURE DIFF differential pulse encoder 4 : CLOCK/DIR DIFF differential pulse encoder 5 : CLOCK DIFF differential pulse encoder 6 : SINCOS INC sin/cos encoder 7 : ABS ENDAT STsingle turn endat absolute encoder 8 : ABS ENDAT MT multi-turn endat absolute encoderSave the ApplicationRemember to save your new configuration in DSE 890 and install it in the drive.

It is designed for balanced transmission lines and meets TIA/EIA-422-B,TIA/EIA-485-A, and ITU Recommendation V.11.The TL3695 combines a 3-state differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively,which can be externally connected together to function as a directional control. The driver differential outputs and the receiver differential inputs are connected internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or V CC = 0. This port features wide positive and negative common-mode voltage ranges, making the device suitable for party line applications.The TL3695 is characterized for operation from 0°C to 70°C.Copyright © 1999, Texas Instruments IncorporatedPRODUCTION DATA information is current as of pub ication date.Products conform to specifications per the terms of Texas Instruments standard warranty.

Circuit Description The TLE4925/TLE4925C is comprised of a supply voltage regulator, a pair of hall probes, spaced at 2.5mm, differential amplifier, noise-shaping filter, comparator, advanced digital signal processor (DSP), A/D and D/A converter and an open drain output. Startup mode: The differential signal is digitized in the A/D converter and fed into the dsp part of the circuit. There a rising or falling transition is detected and the output stage is triggered accordingly. As the signal is not offset compensated at this time, the output does not neccessarily switch at zero-crossing of the magnetic signal. Signal peaks are also detected in the digital circuit and their arithmetic mean value can be calculated. The offset of this mean value is determined and fed into the offset cancellation DAC. This procedure can be repeated with increasing accuracy. After few increments the IC is switched into the high accuracy running mode.

Pin Definitions and Functions
Circuit Description (see Figure 2)
The TLE 4921-5U is comprised of a supply voltage reference, a pair of Hall probes spaced at 2.5 mm, differential amplifier, filter for offset compensation, Schmitt trigger, and an open collector output.
Functional Description
The Differential Hall Sensor IC detects the motion and position of ferromagnetic and permanent magnet structures by measuring the differential flux density of the magnetic field. To detect ferromagnetic objects the magnetic field must be provided by a back biasing permanent magnet (south or north pole of the magnet attached to the rear unmarked side of the IC package).
Protection is provided at the input/supply (pin 1) for overvoltage and reverse polarity and against over-stress such as load dump, etc., in accordance with ISO-TR 7637 and DIN 40839. The output (pin 2) is protected against voltage peaks and electrical disturbances.

The TLE 4921-5U can be exploited to detect toothed wheel rotation in a rough environment. Jolts against the toothed wheel and ripple have no influence on the output signal.
Furthermore, the TLE 4921-5U can be operated in a two-wire as well as in a threewire-configuration. The output is logic compatible by high/low levels regarding on and off.

The differential Hall Effect sensor TLE 4921-5U provides a high sensitivity and a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. TLE 4921-5U is particularly suitable for rotational speed detection and timing applications of ferromagnetic toothed wheels such as anti-lock braking systems, transmissions, crankshafts, etc. The integrated circuit (based on Hall effect) provides a digital signal output with frequency proportional to the speed of rotation. Unlike other rotational sensors differential Hall ICs are not influenced by radial vibration within the effective airgap of the sensor and require no external signal processing.

The TLE 4921-5U was designed to have a wide range of application parameter variations. Differential fields up to ± 80 mT can be detected without influence to the switching performance. The pre-induction field can either come from a magnetic south or north pole, whereby the field strength up to 500 mT or more will not influence the switching points. The improved temperature compensation enables a superior sensitivity and accuracy over the temperature range. Finally the optimised piezo compensation and the integrated dynamic offset compensation enable easy manufacturing and elimination of magnet offsets.
