(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 servomotor capacity.
Operation status of the emergency stop, the servo amplifier forced stop, and
the Motion controller forced stop are as follows.

Operation of
the signal ON
Remark
Emergency stop
Servo OFF
The main circuit power supply of the servo amplifier is shut
off by external circuit and the servo motor is stopped.
Servo amplifier
forced stop
A stop command from the external circuit to the servo
amplifier is output and the servo amplifier stops the servo
motor.
Motion controller
forced stop
A stop command from the Motion controller to the servo
amplifier is output and the servo amplifier stops the servo
motor.
