Proportion control PC CN1B
8
Connect PC-SG to switch the speed amplifier from the
proportional integral type to the proportional type.
If the servo motor at a stop is rotated even one pulse due to
any external factor, it generates torque to compensate for a
position shift. When the servo motor shaft is to be locked
mechanically after positioning completion (stop), switching
on the proportion control signal (PC) upon positioning
completion will suppress the unnecessary torque generated
to compensate for a position shift.
When the shaft is to be locked for a long time, switch on the
proportion control signal and torque control signal (TL) at
the same time to make the torque less than the rated by the
analog torque limit.

Emergency stop EMG CN1B
15
Disconnect EMG-SG to bring the servo motor to an
emergency stop state, in which the servo is switched off and
the dynamic brake is operated.
Connect EMG-SG in the emergency stop state to reset that
state.
DI–1
Clear CR CN1A
8
Connect CR-SG to clear the position control counter on the
leading edge of the signal. The pulse width should be 10ms
or more.
