After the alarm (ALRM) occurs, this signal is used to
reset the drive to output the Ready (SRDY) signal
again.
GAINUP
ALL
It is used to switch the controller gain.
CCLR
P
It is used to clear the error counter.
ZCLMP
ALL
If this signal is ON and the motor speed is below the
setting value of the parameter PC-20, the position of
the motor is locked to the one that the signal is
generated instantly.
