∗1 The priorities of the frequency commands when Pr. 79 = "3" are "Multi-speed operation (RL/RM/RH/REX) > PID control (X14) > terminal 4 analog input (AU)
> digital input from the operation panel".
∗2 For the terminal used for the X12 signal (PU operation interlock signal) input, set "12" in Pr. 178 to Pr. 182 (input terminal function selection) to assign functions.
Refer to Chapter 4 of the Instruction Manual (Applied) for Pr. 178 to Pr. 182.
When the X 12 signal has not been assigned, the function of the MRS signal switches from MRS (output stop) to the PU operation interlock signal.
