How does PLC control the stepper motor through CAN bus

Step 1: Material preparation

1. PLC: Delta DVP28SV11R2

2. CAN communication module: DVPCOPM-SL-CANopen

3. CAN bus integrated stepper motor: PMC007C6SEP 42-47

4. Computer

Step 2: Build the control network as shown below

Step 3: CAN configuration


Open the CAN configuration software and select CANopen configuration

Slave station-equipment manufacturer-Telemecanuque-double-click PMC007xx to join the slave station, taking a configuration as an example:

Add Slave

Slave configuration: Slave RxPDO configuration

Configure Slave

Add the mapping object 6003 to be configured as shown in the figure below, add 601c in the same step and click OK

Add mapping object

Slave configuration: Slave TxPDO configuration, follow RxPDO configuration to complete the following configuration

TxPDO configuration

Master station configuration: double-click the master station-click the configured slave station-click> join the configured master station

Master station configuration

Complete the master-slave mapping configuration as shown below: here you need to pay attention to the master station address and slave station address, the settings on the device need to be the same as the addresses configured on the configuration software

The fourth step: PLC sends data to the slave station through PDO, and monitors the slave station to return data

Open the programming software: After online, create a monitoring table as shown below

PLC communication port configuration

Open the programming software: After online, create a monitoring table as shown below

Create device monitoring table

By writing values to the mapped speed address D6282 and position address D6284, the PLC can control the stepper motor through the PDO of the CAN bus
