(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 and the forced stop are as follows.

the signal ON
Remark
Emergency stop
Shut off the power supply to the external servo amplifier
by external circuit, make the servomotor stopped.
Forced stop
Servo OFF
The servomotor is stopped according to the stop
instruction from Motion controller to the servo amplifier.
