For the terminal used for the X12 signal (PU operation interlock signal) input, assign "12" in
Pr. 178 to Pr. 189 "input terminal function selection" to assign functions. For Pr. 178 to
Pr. 189, refer to section 6.9.1. When the X12 signal is not assigned, function of the MRS
signal switches from MRS (output stop) to PU operation interlock signal.
NOTES Use the simple setting mode to set Pr. 79 in simple steps.
If switching of the operation mode is invalid even though Pr. 79 is set, check the related
notes of troubleshooting (refer to section 7.6.9).
