Use any of Pr. 60 to Pr. 63 (input terminal function selection) to set the terminal
used for X16 signal input.

2) Function

This switching is enabled during an inverter stop only and cannot be achieved
during operation.

REMARKS

•If the MRS signal is on, the operation mode cannot be switched to the PU operation mode

when the start signal (STF, STR) is on.

*1. The operation mode switches to the external operation mode independently of whether the

start signal (STF, STR) is on or off.
Therefore, the motor is run in the external operation mode when the MRS signal is
switched off with either of STF and STR on.

*2. Switching the MRS signal on and rewriting the Pr. 79 value to other than "7" in the PU

operation mode causes the MRS signal to act as the ordinary MRS function (output stop).
Also as soon as "7" is set in Pr. 79, the signal acts as the PU interlock signal.

CAUTION

When terminal assignment is changed using Pr. 60 to Pr. 63, the other
functions may be affected.
Check the functions of the corresponding terminals before making settings.
For details refer to page 102.
