HEIDENHAIN iTNC 530 HSCI Service Manual

19.2.5 Troubleshooting
To find out, whether the connected encoder or the encoder interface of the control component is
defective, the interchange method can be used.
Exchange
constellations
Note
Encoder error messages are mostly due to the encoders / signal sockets / cables. In rare cases,
the reason is a defective interface of a CC or UEC.
The interchange method is quite complex here, as in addition to the speed encoder inputs, you
also have to swap the position encoder inputs and the PWM outputs or motor outputs, and you
must adapt the parameter settings.
Checking the suspicious speed encoder with a PWM 9 or a PWT 18 may be more effective.
