Error Localization by Process of Interchange

For checking machine-tool components that are available more than once (servo amplifiers,
motors, expansion boards, etc.) the "interchange method" can be used.
To do this, interfaces or identical devices are interchanged in order to find out, whether the error
"moves".
Example:

For detailed descriptions on how to interchange devices, please refer to the respective chapters
of this Service Manual or to the Service Manual for Inverter Systems and Motors.

Interchange of position encoders -->
See "Position Encoders" on page 18 – 277.
Interchange of speed encoders -->
See "Speed Encoders" on page 18 – 293.
Interchanging PWM interfaces -->
See "Digital PWM Interface" on page 20 – 323.
Interchanging expansion boards -->
See "Troubleshooting: Interchanging the HEIDENHAIN interface boards for the SIMODRIVE
611 system" on page 20 – 342.
Interchanging inverters, motors -->
See "Service Manual for Inverter Systems and Motors".
Caution
For trouble shooting do not connect obviously defective controls (e.g., position encoder with
short circuit after entering of humidity) to other interfaces (e.g., X1-X6, X35-X38) of the
control.
