Relative Parameters
Note: For Absolute Modbus numbers, add 40001 to the Relative number.
Note: Refer to p. 7.7 for Modbus Register Numbers for ramping parameters.
Special Modbus Functions
The following are modbus registers with special functions. Disable Non-volatile Memory (24); Alarm Status
Output 2 (106); Alarm Status Output 3 (110); Auto-Manual Operation Mode (200); Clear Input Errors (311);
Clear Alarms (331); Silence Alarms (332).
A “0” indicates an active state. Send “1” to the register to activate the function. It will automatically reset
to “0” when the function is complete.
