Configure the PLC parameters.
Note:
Keep the PLC baud rate the same as the drive setting.
Set even parity check for the PLC (parity = 2).
Set a way for PLC sending message to slaves. Here we use the unicast mode and we
only want to send the message to slave 1.
Note:
If you want to send the message to all slaves, you need to set the slave address to 0
to use the broadcast mode.
Write the control word you desired via the register 40100.
Note:
Bit 10 of the register 40100 must be set to 1 to allow the PLC to control the drive.
You need to trigger a rise edge for OFF1 to enable SON status for the motor, and
OFF2 and OFF3 must be set to 1. The step must be executed when you enable SON
for the first time.
For example, we write 0x41E to the register 40100 firstly and then write 0x41F to the
register. The motor now is in SON status. You can check the control word definition
table below to see the meaning of "0x41E" and "0x41F".
