RS-485 Command Port
A 2pin command port is available on the drive for debug and tuning routines. The communication is based
on Modbus RTU, the drive works as Modbus Slave and its register map is given in the Modbus Register
Table.
When connected it to a computer the drive parameters can be accessed by simple commands using any
Modbus Master Poll Software. An additional hardware to execute this process would be a USB to RS485
Converter. The baud rate of 115200 bps is default with 8 bit data, 1 stop bit and no parity.
The Modbus RTU Functions 03 (Read Multiple Registers), 05 (Write Single Coil) and 06 (Preset Single
Register) are used to control the drive.
