stopped and power switched off immediately.
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.
