Smart digital conveyor control system using only VFDsOverviewNo matter the industry, variable frequency drives (VFD) can help simplify operations at every stepof the application, from the initial implementation through troubleshooting in your environment. With cascaded conveyors often working 24/7to deliver materials, it is important that they arein-sync to ensure maximum efficiency and minimal jamming, making the emergency stop mechanism a vital safety feature for personnel and equipment. While some large material handling systems, such as those in thermal power plants, require human interface to utilize a programmable logic controller (PLC) or distributed control system (DCS), less complex systems, such as a conveyor moving dishes in a cafeteria, can rely solely on VFDsthat are wired and programmed to conduct the cascaded operation.Overall, VFDs provide significant benefits for the entire conveyor system and offer a reliable and cost-effective solution for process control and protecting your equipment.Simple cascaded conveyor system descriptionFigure 1 illustrates a typical system, where eachof the cascaded conveyors would be controlled by an AC induction motor that is controlled by a VFD. These systems also include features like pull-cords and zero-speed switches in addition to any number of sensors, such as proximity, photoelectric, inductive, and vibration monitoring. Along the conveyor system, diverter gates and flaps help ensure materials are correctly routed.Before the digital age, all sensors were wiredto control contactor logic, but with digital VFDs, the sensors are now directly wired to VFDs. In some advanced systems, the sensors can be wired to PLCs.Figure 1. T ypical cascaded conveyor system Typical conveyorsystem operationAll safety features, such as the pull-cords and emergency stops, should be checked to verify system readiness before operation. Depending on the number of sensors and overall fidelity of the conveyor system, the start/stop commandis given manually to each conveyor, or the system can be operated with a master start/stop command with sensors communicating with the individual conveyors.The process logic for a cascaded system is that the first conveyor to start is the last to stop, depending upon the direction that the materials are being moved as guided by the diverters. In Figure 1, conveyor A is the first to start after the command is issued to the system, and conveyor E is the last to start. When stopping the system, conveyor E will be the first to cease operation, while Conveyor A will be the last to stop. The same concept would apply should any of the conveyors in the chain trip a sensor or a motor fault. For example, if conveyor C trips on a fault, then conveyors D and E will stop so that material doesn’t continue piling onto the stopped conveyor C. In a more complex system, the user can choose to divert the materials onto a different path, rather than forcing the stoppage of multiple conveyors.2Application Paper AP040230ENEffective April 2022Smart digital conveyor control systemusing only VFDsEATON Understanding sensor integrationThe most common sensor used in conveyor systems is a zero-speed switch, which provides feedback as to whether the conveyor is moving or has stopped. While an AC induction motor could be moving because VFDs are putting out voltage, the conveyor could actually be stopped. In that case, the zero-speed switch senses the actual movement—or lack thereof—coming from the conveyor belt. In Figure 1, if the zero-speed switch on conveyor C triggers, then the motors on conveyors C, D, and E will stop to prevent materials from piling up and accidental damage.It is important with the implementation of a zero-speed switch in the controls to begin sensing after the conveyor has started running at a certain frequency, but not before the conveyor has started moving. If the zero-speed switch begins sensing before the conveyor is running, then it will never start.When VFDs were less advanced, PLCs were a must for implementing control of a cascaded conveyor system, and before PLCs, hardware-wired relay controls were used. With advancements in the applications offered by VFD digital controls, most of the control functions required by the simple conveyor system (Figure 1) can be achieved by integrating the sensors to, and in the wiring between, the VFDs. Using only VFDs, rather than integrating PLCs with them, is a more cost-effective solution for achieving the same performance.How to integrate a conveyor system digitally with VFDsFor the following section, refer to Figure 1.Start command: A total of five VFDs—one for each conveyor motor—are connected on the control board. Run feedback from conveyor A is wired to conveyor B, and conveyor B is wired to conveyor C, and so on until all conveyors are connected to one another. The start command is issued to conveyor A, and the run feedback starts conveyor B, while conveyor B starts conveyor C, and onward until conveyor E begins moving. This is how VFD controls start all five conveyors.Conveying speed reference control: The main system speed reference input is only fed to conveyor A ’s VFD. Then, all five of the conveyor’s VFDs feed the speed control signal, i.e., A > B > C > D > E. Changing the speed reference to conveyor A subsequently changes the speed of the conveyors upstream that feed material to conveyor A.Stop/fault command: Just like the start command, the stop/fault command works via the five VFDs connected to one another on the control board. When the stop command is issued, conveyor E will be the first to stop, which is wired to then pass the command to conveyor D, and onward through the cascaded conveyors, i.e., E > D > C > B > A. Each conveyor is wired to the next in the chain, which is how the VFD stops all five conveyors. The faultcommand follows the exact same sequence as the stop command.Sensor interface: Users add more sensors to the conveyor system as fidelity increases. The zero-speed switch for each conveyor is wired to its specific external fault, and if triggered, the VFD will issue a fault to automatically stop the subsequent VFDs in the chain. The zero-speed switch can be bypassed by using drive-relay before the drive is running by setting the drive frequency above that of the moving conveyor. Once the relay picks up the preset speed frequency, it arms the zero-speed input on the same channel as the relay for initial bypass of zero-speed sensing. Simple control is achieved by using VFD digital controls without the need for a PLC.The pull-cords of the conveyors can be wired in series to the STO of the drives. This is the safest way to put an emergency stop on the drives running the motor and is possible to achieve with only VFDs.Figure 2. T ypical relay wiring for zero-speed sensingProximity sensors: Proximity sensors can be connected to the VFDs for a more intelligent start/stop by sensing the materials on the conveyor. Instead of running the systems continuously, it can be started and stopped based on the load that is traveling on the conveyor. This power-saving option enables the VFD to give a start command to the next conveyor in the cascade, only in the event it needs to be activated.Referring again to Figure 1, the proximity sensor would detect a load on conveyor E, and as soon as the load reaches a preset point, it would give a start command to conveyor D and so on until it reaches conveyor A.The same logic applies to the stoppage of conveyors. If the load falls below a certain preset threshold, it triggers a command to the rest of the conveyor system that a load isn’t being transported, thus turning it off to save power.Maintenance management: Sensors with vibration monitoring capabilities can be wired directly to the VFD to trigger a warning and generate a fault command to prevent damage to the system.Use of DM1 for a conveyor applicationSelection of DM1 modelBased on motor current selected for the conveyor, the user can select the DM1 model that supports 150% of the overload. DM1 is available in models capable of 110% or 150% overload for 60 seconds, but the conveyor application requires constant torque. Because of that, the 150% overload model (also known as an IH model) is recommended.In certain applications, the drive is required to deliver 200% overload, and the DM1 can deliver at that level for 2 seconds, every 20 seconds. After delivering the required torque in the overloaded zone, the drive will safely trip if the load demands higher torque for an extended period of time.Power and control wiring of DM1The DM1 installation manual will help determine recommended fuse protection and cable sizes, based on frame size and model. The manual also contains recommendations for grounding, EMC, brake resistor, and control wiring. Users should follow the design guidelines from the manual.Figure 3 shows typical control wiring for the DM1.3Application Paper AP040230ENEffective April 2022Smart digital conveyor control system using only VFDs EATON Figure 3. T ypical control wiring schemePlanning fieldbus control for the conveyorAs illustrated above, the control can be wired to the drive. If the conveyor system has a PLC, the DM1 Pro model offers onboard EtherNet/IP connection or, as an option, a Profibus T card forcontrolling and reading drive data via fieldbus link. The Modbus T RTU is available with every model.Eaton has developed Add-On Instructions (AOIs) for Rockwell PLC that support various assemblies, allowing for simple import to the Rockwell Studio5000, and used in PLC programming for controlling start/stop and speed reference to the DM1 drive. AOI also supports the data read from the PLC. For protocols and application notes to support PLC code implementation, refer to the quick start guide.DM1 software features for controlling conveyors Motor controlMotor control mode: The conveyor application can be run using V/F scalar control or Sensorless Vector Control (SVC). In V/F control mode, DM1 can offer +/–0.5% of base speed across a 30:1 speed range. If the speed reference to the conveyor is changing frequently, SVC control is recommended, which will provide +/–0.5% speed accuracy across a 60:1 speed range for the application.Speed reference: DM1 offers fixed speed reference throughdigital inputs that can be preset for speed reference, or the speed references can be an analog input or Fieldbus control register. DM1 offers various speed acceleration and deceleration profiles built into the drive control algorithms that can be selected by the user to minimize the equipment wear and tear.Start/stop mode: Ramp start/stop applications are typically used for conveyors, but DM1 also offers flying-start if required.Because particular conveyor applications might require a fast start/stop, the minimum programmable deceleration rate offered by DM1 is one-tenth of a second (0.1), but due to load inertia, actual stop time will vary.If the user desires a faster ramp rate than one-tenth of a second (0.1), the user can change the P1.2 setting. The user should make sure the speed reference is tethered to the motor design nominal speed, even though the P1.2 is set higher.For example, P 1.4 = 0.1 sec, P1.1 = 0, and P1.2 = 60 Hz If the drive is running at 40 Hz, then it will take(0.1/60) x 40 = 0.07 sec to drop to 0 Hz and 0.1 sec if the VFD was running at 60 Hz.Then, P 1.4 = 0.1 sec, P1.1 = 0, and P1.2 = 400 Hz The same thing changes if 40 Hz, then it will take(0.1/400) x 40 = 0.01 sec to drop to 0 Hz and 0.015 sec if the VFD was running at 60 Hz.For applications requiring multiple rapid starts/stops, an external dynamic braking resistor (DBR) should be considered, based on application duty cycle and the drive rating recommended in the catalog.Using an overvoltage (OV) regulator in the conveyor application to control the DC bus overvoltage is not recommended, as powermust be rapidly drained from the DC bus to achieve the fastest stop. When using the brake-chopper for external DBR, the user should disable the OV regulator in DM1.DC braking: Along with an external DBR, users can stop the conveyor via DC or flux brakes built into the DM1 drive. Because of the various field variables, it is recommended that brakingperformance is type-tested to determine the required performance.Application notes are available to support DC brake setup.Eaton1000 Eaton Boulevard Cleveland, OH 44122 United States © 2022 EatonAll Rights ReservedPrinted in USAPublication No. AP040230EN / Z26202 April 2022Eaton is a registered trademark.All other trademarks are propertyof their respective owners.Smart digital conveyor control systemusing only VFDsApplication Paper AP040230EN Effective April 2022Application controlIn addition to the standard start/stop control of the DM1, all models have a built-in PI controller for drive speed based on the process-control feedback.The PI controller is available for both inverted and non-inverted actions, and should be selected by the user based on the process. The DM1 Pro model offers more applications than the standard DM1 model.For a model comparison, reference the DM1 application manual. ProtectionsDM1 is a smart digital drive, offering protections to the drive itself, connected motor, and communications interface.Protections include—but are not limited to—motor thermal protection, input phase fault, external interlock fault, undervoltage and overvoltage, and loss of PI feedback.Additionally, the drive supports automatic restarts for certain faults, with the user selecting how many times the drive may restart during a predetermined period.T able 1.

STO prevents an unexpected start of the motor, and therefore, stops the drive from producing power/torque to the load. This feature is particularly useful for maintenance and personnel protection.The STO trigger is a stop command to the drive, forcing the motor to coast to a stop. This function is initiated through the hardware circuit rather than the software, disabling the output IGBTs by either disconnecting the power supply to the gate control driver IC (STO1) or disabling the output of the gate control driver IC (STO2).The gate-drive output signals control the IGBT module, andwhen they are disabled, the drive will not generate torque in the motor shaft.More detailed application notes for STO wiring configurationsare available.Figure 4.
