Group F12: Simple PLC Function And Multi-speed control
The multi-command has many functions. Besides multi-speed, it can be used asthe setting
source of the V/F separated voltage source and setting source of process PID. In addition,
the multi-command is relative value.
The simple PLC function is different from the user programmable function. Simple PLC can
only complete simple combination of multi-command, while the user programmable function
is more practical.

Simple PLC can be either the frequency source or V/F separated voltage source.
When simple PLC is used as the frequency source, whether parameter values of F12.02 to
F12.17 are positive or negative determines the running direction. If the parameter values are
negative, it indicates that the AC drive runs in reverse direction.
