Emergency stop
For safety’s sake an EMERGENCY OFF switch must always be installed between the terminals
EM1 and SG. When the contact is interrupted, the servo motor is switched to a resistance brake
(dynamic brake) integrated into the unit and brought to a stop as soon as possible.
Simultaneously the EMERGENCY OFF message (E6) appears on the display.
During ordinary operation, do not use emergency stop circuit to alternate stop and run.
