16.9 EMERGENCY STOP
(1) For permissible main and control voltage values (dependent on article number), refer to
chapter Technical data (Page 127).
(2) Automatic restart. Can result in death, serious injury, or property damage.
The start command (e.g. issued by the PLC or switch S1) must be reset prior to issuing a
RESET command because the motor attempts to restart again automatically following this
RESET command (3TK or 3RW) if a start command is still present. This particularly applies
if the motor protection has tripped. For safety reasons, you are advised to integrate the
group fault output (terminals 95 and 96) in the controller.
(3) Alternatively, the motor feeder can be assembled as a fuseless or fused version with type
of coordination 1 or 2. For the assignment of fuses and switching devices, refer to chapter
Technical data (Page 127).
For the optional thermistor motor protection evaluation, refer to Typical circuit for the optional
thermistor motor protection evaluation (Page 161).
Note
If the soft stop function is set (potentiometer stopping time set to >0 s) and the emergency
stop circuit is tripped, a "Missing load voltage, phase failure / missing load" fault may be
indicated on the soft starter. In this case, the soft starter must be reset according to the
selected RESET MODE.
