*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. 189 (input terminal function selection) to assign
functions.
For Pr. 178 to Pr. 189, refer to Chapter 4 of
When the X12 signal is not assigned, function of the MRS signal switches from MRS (output stop) to PU operation interlock signal.
