20.1.8 Troubleshooting: Interchanging the HEIDENHAIN interface boards for the SIMODRIVE 611 system
If a SIMODRIVE 611 system is used in combination with the HEIDENHAIN control, there are
HEIDENHAIN interface boards in the SIEMENS drive modules to adapt the PWM signals.
Boards of the same
type
Before using other drive modules for the examination of faulty axes, you may exchange
dimensionally identical expansion boards.
Please observe:
 Exchange the boards while the machine is switched off.
 Exchange boards of the same type (1-axis module or 2-axis module, metallically isolated or not
metallically isolated. --> See ”Exchange of HEIDENHAIN Components in the SIMODRIVE
System” on page 28 – 554).
 The grounding must be correct. --> See ”Exchange of HEIDENHAIN Components in the
SIMODRIVE System” on page 28 – 554.
Boards of different
types
If you do not have boards of the same type, under certain circumstances you may exchange
boards for 1-axis modules for boards for 2-axis modules and vice versa.
Difficulties can be:
 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 entire board is not enabled.
 If a 1-axis module board is inserted in a 2-axis module for testing, the corresponding axis can
be inspected.
If the other axis is to be inspected, the motor output on the power stage must be switched.
For these tests it might be necessary to deselect axes that cannot be controlled in MP 10.
With some machines this might be difficult.
--> Ask your machine tool builder!
Caution
When troubleshooting do not insert obviously defective devices into the slots of the drive
system!
Caution
Boards with metallic isolation of HEIDENHAIN PWM signals and SIEMENS interface must
not be replaced by boards without metallic isolation and vice versa. --> See “Overview of
Possible Error Patterns” on page 5 – 55.
Caution
"Older" HEIDENHAIN expansion cards must not be operated with modified SIMODRIVE
power modules. --> See “Compatibility of HEIDENHAIN interface boards and SIMODRIVE
power modules” on page 28 – 559.
