7.2.1 The protocol is Modbus protocol. Besides the common register Read/Write operation, it is

supplemented with commands of parameters management.

7.2.2 The drive is a slave in the network. It communicates in ‘ point to point ’ master-slave mode. It will not

respond to the command sent by the master via broadcast address.

7.2.3 In the case of multi-drive communication or long-distance transmission, connecting a 100~120 Ω

resistor in parallel with the master signal line will help to enhance the immunity to interference.
