HEIDENHAIN TNC 426 PB/M User Manual

6 – 172 HEIDENHAIN Technical Manual TNC 426, TNC 430
6.11.11 Status of HEIDENHAIN Inverters
All HEIDENHAIN inverters, except the UE 2xx compact inverters and non-
HEIDENHAIN inverters, provide the error signal ERR-IZ
in the event of an
excessive dc-link current at X69.
For HEIDENHAIN inverters except the UE 2xx compact inverters:
7
77
7 Activate the monitoring function for the ERR-IZ signal with
MP2221 bit 2 = 1.
After the monitoring function has been activated and the signal has appeared,
n The torque-producing current for the spindle is limited to 70 % of the
present current on the LE 426 M/12000 rpm
For HEIDENHAIN UE 2xx compact inverters and non-HEIDENHAIN inverters:
7
77
7 Deactivate the monitoring function for the ERR-IZ signal with
MP2221 bit 2 = 0.
After the monitoring function has been deactivated, the control continues
working until the inverter switches off.
With module 9066, further status information on the HEIDENHAIN inverters
can be read in the PLC.
