For external damage to the cover
plates, e.g. caused by closing the
welding gun on the gearbox, the
complete gear unit should be
replaced. In this case also the
programming of the robot must be
corrected.

The devices are supplied in the following variations:
(3a) Simple (inductive) rotary query (1 LED) that supplies a pulsating
24 V digital signal according to the number of contact surfaces in the
tool.
(3b) Integrated (inductive) speed evaluation (3 LED), which
evaluates the cutting speed of the device and shuts down at the
minimum speed of the digital 24-volt signal.
Without rotary sensing. The correct operation of the device is
monitored in the motor control.
