Group FC: Multi-Reference and Simple PLC Function
The MD380 multi-reference has many functions. Besides multi-speed, it can be used as the
setting source of the V/F separated voltage source and setting source of process PID. In
addition, the multi-reference is relative value.
The simple PLC function is different from the MD380 user programmable function. Simple
PLC can only complete simple combination of multi-reference, while the user programmable
function is more practical. For details, see the descriptions of group A7.

Multi-reference can be the setting source of frequency, V/F separated voltage and process
PID. The multi-reference is relative value and ranges from -100.0% to 100.0%.
As frequency source, it is a percentage relative to the maximum frequency. As V/F
separated voltage source, it is a percentage relative to the rated motor voltage. As process
PID setting source, it does not require conversion.
Multi-reference can be switched over based on different states of DI terminals. For details,
see the descriptions of group F4.
