Troubleshooting: Interchanging Power Modules Or Output Stages Of The Same Type - HEIDENHAIN iTNC 530 Service Manual

20.1.7 Troubleshooting: Interchanging power modules or output stages of the same type

If you have found out that the PWM interface on the CC 422 oder CC 424 (B) is in order, you can
test whether you can traverse the faulty axis with ...
Use one of the following:
July 2010
an identical power module (modular inverter system) or
an output stage with equal power (2-axis-module, compact inverter)
.
DANGER
If you want to use other types of power stages or output stages, we strongly
recommend contacting your machine manufacturer or HEIDENHAIN. Otherwise you could
cause damage or injury to machine or persons!
Either the power stage or output stage of a functioning axis
Or a replacement unit
Note
It is not necessary to exchange a machine parameter for this test routine!
It is of no importance, whether the power stages in the machine are from HEIDENHAIN or
other manufacturers.
DANGER
Before you connect drives to other interfaces for error localization:
Make sure that there are no ground faults or short circuits in the drive components
(inverters, motors, etc.) --> See service manual "Inverter Systems and Motors".
DANGER
Always secure vertical axes from falling down before you perform this test!
DANGER
Danger of electrical shock!
Make sure that the main switch of the machine is switched off and that all connectors and
terminals are free of potential before you engage or disengage them.
