forced stop
(b) The forced stop of all servo amplifiers is possible in a lump by using the
forced stop input of input modules. After forced stop, the forced stop factor is
removed and the forced stop canceled.
(The servo error detection signal does not turn on with the forced stop.)
The forced stop input can be set by allocation of the device number in the
parameter setting of system setting. When the device is used, apply 24VDC
voltage on EMI connector and invalidate the forced stop input of EMI
connector.
The wiring example that uses the forced stop input of input module (QX10)
is shown below.

(c) It is also possible to use the forced stop signal of the servo amplifier.
Refer to manual of the servo amplifier about servo motor capacity.
Operation status of the emergency stop, servo amplifier forced stop, and the
Motion controller forced stop are as follows.

(Note): The forced stop input can be set in the system settings.
The power supply of the servo amplifier is shut off by
external circuit, and the servo motor stops.
A stop command from the external circuit to the servo
amplifier is output, and the servo amplifier stops the
servo motor.
A stop command from the Motion controller to the servo
amplifier is output, and the servo amplifier stops the
servo motor.
