Error Finding: Swapping Power Modules Or Output Stages Of The Same Type - HEIDENHAIN iTNC 530 HSCI Service Manual

21.1.9 Error finding: Swapping power modules or output stages of the same type

If you have found that the PWM interface on the CC 61xx is in order, you can test whether you can
traverse the faulty axis with ...
Use one of the following:
Assumed UM 111D:
configuration for
two 1-axis power
UM 111D:
modules
Assumed UM 121D:
configuration for
a 2-axis power
module
Assumed UM 242 D:
configuration for
a compact inverter
February 2012
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 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 swap any machine parameters 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 to prevent them 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.
