Motor:
Short circuit surveillance: NOK
Motor short circuit monitoring
There is a short circuit in the
motor circuit on the DGD-IS
in the motor Check the motor for short circuits
(for phase impedances, see
above)
➔ Replace motor
In the TSE/TUSE Internal error
➔ Replace the TSE/TUSE
Motor:
Temperature: NOK
The motor temperature is > 90 °C
The temperature sensor in the
motor measures a temperature
> 90 °C
Check the motor temperature,
if > 90 °C
➔ ensure adequate ventilation
of the motor
Measuring cable in the motor is
interrupted
Check the thermosensor for
breaks. The resistance should be
approx. 1 K at 20 °C
➔ Replace motor
Measuring current is misdirected Check the wires in the DGD-IS
for breaks and short circuits
➔ Replace motor
Measuring current is not mea-
sured
Internal error,
➔ Replace the TSE/TUSE
Motor is not connected
➔ Connect the motor
Motor:
I
2
t monitoring: NOK
The I²t monitor has measured
excessive power on the DGD-IS
Motor power required is too high Check the motor temperature,
if > 80 °C
➔ Shorten the fastening time by
increasing the speed
DGD-IS is defective (i.e. gear-
ing, bearings)
Check the ease of movement of
the gearing and motor on the
DGD-IS
➔ Replace the DGD-IS or motor
Motor:
Resolver: NOK
No resolver signals measured
Signals are not present Check whether the motor is con-
nected
➔ Connect the motor
Signal interruption Check the resolver wires in the
DGD-IS
➔ Replace motor
Short circuit of signals Check the resolver wires in the
DGD-IS for short circuits
➔ Replace motor
Supply to the resolver is defec-
tive
Internal defect
➔ Replace the TSE/TUSE
Measurement card:
Task monitoring: NOK
Error at the program execution
end of the measuring board
Internal error
➔ Replace the TSE/TUSE
➔ Inform DGD service
Measurement card:
