Product description
Motor OFF protective circuit
1. Cut-out via the internal motor contactors
After a cut-out via the motor contactor, the
motor phases are electromechanically iso-
lated from the power supply.
Fig. 9: Motor OFF circuit 1 (NH1) connection to the Compact System
Motor Off switch directly connected to the
contacts for motor OFF
If the S1 motor breaker switch is actuated,
the motor of the hand-held nutrunner/tighten-
ing spindle will be decelerated by the servo
amplifier and the internal contactor in the
compact system will be opened. This tighten-
ing job abort leads to an error message in the
controller. The error message is automatically
acknowledges once switch S1 is closed
again. Now you can restart the system.
