Related Parameters
The following parameters need to be set correctly to insure proper operation of the iQpump drive when using Modbus communication.
Table 20 Serial Communication Related Parameters
Modbus communication can perform the following operations regardless of the settings in b1-01 and b1-02:
1. Monitoring operation status of the Drive
2. Setting and reading iQpump drive parameters
3. Resetting faults
4. Input multi-function commands
Important: An OR operation is performed between the multi-function command input from the PLC and the command input from multi-
function digital input terminals S3 to S7.
