3. SIGNALS AND WIRING
(3) Emergency stop
CAUTION
Make up a circuit that shuts off main circuit power as soon as EMG is turned off at an emergency stop.
When EMG is turned off, the dynamic brake is operated to bring the servo motor to a sudden stop. At
this time, the display shows the servo emergency stop warning (AL.E6).
During ordinary operation, do not use the external emergency stop (EMG) to alternate stop and run.
The servo amplifier life may be shortened.
Also, if the forward rotation start (ST1) and reverse rotation start (ST2) are on or a pulse train is input
during an emergency stop, the servo motor will rotate as soon as the warning is reset. During an
emergency stop, always shut off the run command.
Emergency stop
Provide an external forced stop circuit to ensure that operation can be stopped and
power switched off immediately.
