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:

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,

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:

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.

Current and speed controller monitoring functions

0: Do not monitor ERR-IZ signal, or inverter does not supply this

1: Monitor ERR-IZ signal
