Trouble Shooting: Exchanging The Heidenhain Interface Boards For The Simodrive 611 System - HEIDENHAIN iTNC 530 Service Manual

20.1.6 Trouble Shooting: Exchanging the HEIDENHAIN Interface Boards for the SIMODRIVE 611 System

If a SIMODRIVE 611 system is used in connection with the HEIDENHAIN control, there are
HEIDENHAIN interface boards in the Siemens drive modules to adapt the PWM signals.
Boards of the Before using other drive modules for examination of faulty axes, you may exchange
same type dimensionally identical expansion boards.
Observe the following:
Boards of If you do not have boards of the same type, under certain circumstances you may exchange
different types boards for 1-axis modules for boards for 2-axis modules and vice versa.
Difficulties can be:
20 – 340
The machine is not under power when you exchange the boards
Boards of the same type are exchanged (1-axis module or 2-axis module, metallically isolated
or not metallically isolated --> See "Important Notes on the Use of HEIDENHAIN Interface
Boards in SIMODRIVE System" on page 5 – 29)
The grounding is correct --> See "Important Notes on the Use of HEIDENHAIN Interface
Boards in SIMODRIVE System" on page 5 – 29
Some 2-axis module boards (ID number smaller than 359002-xx) require the corresponding
enabling signals of the control on every PWM interface. If such a board is inserted in a 1-axis
module and one PWM interface is not assigned, the complete board is not released.
If a 1-axis module board is inserted in a 2-axis module for test purposed, the corresponding
axis can be inspected (if the other axis is to be inspected, to motor output on the power stage
must be reconnected).
For these tests it might be necessary to deselect axes that cannot be contolled by MP 10.
With some machines this might be difficult.
--> If necessary, ask the HEIDENHAIN service agency!
Caution
Boards with metallic isolation of HEIDENHAIN PWM signals to the Siemens interface must
not be replaced by boards without metallic isolation and vice versa!
