3.3 Thermal protection of the motor
To protect the motor from overheating, the motor winding is continuously monitored by a thermostat connected
to the terminals TEMP1 and TEMP2. Whenever an overload or overtemperature condition occurs, the NORDAC
connect will switch off the drive automatically.
If the enable signal [RUN] is not removed, the drive will start up again on its own when the
motor temperature has sufficiently decreased.
To prevent the drive from restarting automatically, evaluation of the readiness-for-operation acknowledgement
[OK] signal can be assigned to a control device (PLC).
3.4 Three-phase brake motors with a NORDAC connect
Whenever a three-phase brake motor is combined with a NORDAC connect motor switch, the wiring needed to
connect the brake is taken care of at the factory.
The brakes used have got a coil voltage of 180 V DC. They are connected to terminals BR1 and BR2 .
