I tried turning the FWD bit ON as you outlined in your last response. However, I was still unable to get a response from the motor (beyond connection) using a Modbus programming library.
Given these issues, I'd like to verify I can successfully write a Modbus command outside of the Modbus library by using Comtest Pro as suggested in another post here. However, when I try this, I get "communication error: no response received" from Comtest. This happens if I try to read or write any registers. Do you have any suggestions on how to can find the problem via Comtest or some other software? I've included relevant settings on the driver and software below.

(Comtest) Step 1 settings: COM1 (checked with Windows), 115.2k (set on driver: see below), 8 bits, no parity, 1 stop bit.
Communication and power: I have the motor cable, 120V AC, 24V DC, and your CC-link USB cable connected to the driver.
