RUN Permission Signal
A RUN command is accepted only while the RUN permission signal is ON. 
To use this function, allocate "84: ROK" to the multi-function input terminal.
Multi-step Speed Operation Function (CF1 to CF4, SF1 to SF7)
Multiple RUN speeds can be set in parameters and the applicable speed can be switched
using the terminals. 
For multi-step speed operation, either 4-terminal binary operation (with maximum 16 steps) or
7-terminal bit operation (with maximum 8 steps) can be selected.
