Emergency stop
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 terminal and invalidate the forced stop input of EMI terminal.
The wiring example that uses the forced stop input of input module (QX10)
is shown below.
