1. Calculate the supporting motor speed using the equation below: Speed = 120*frequency/number of poles for motor 2. The AC motor drive has two RS485 communication ports as indicated in the diagram below (Channels 1 &2). a. Channel 1: One common port for RJ45 and RJ11 b. Channel 2: Two RJ45 ports and a terminal c. Communication protocol for channel 1 is 19200, 8, N, 2 d. The default setting for the drive station is 1 and the PLC station is 2. According to the C2000 user manual Chapter 16-2, the default setting for the PLC communication protocol is 7,N,2 ,9600; the station is 2. The user may change the PLC station from Pr.9-35, but the address should not be the same as the drive’s address in Pr.9-00. The communication protocol can also be changed by Pr.09-04.
