Exchange Of Further Heidenhain Components - HEIDENHAIN iTNC 530 Service Manual

26.7 Exchange of Further HEIDENHAIN Components

26 – 442
Many HEIDENHAIN units (encoders, scanning heads, etc.) are delivered with mounting
instructions in the packaging.
The HEIDENHAIN testing equipment PWM 9 or PWT is helpful for the adjustment of scanning
heads.
When exchanging electrical original components (inverters, motors, etc.) a new
adjustment of control loops of axes and spindle is normally not necessary.
Exception: When exchanging an MC that also (or exclusively) controls analog axes, an offset
adjustment with the code number for the fine compensation should be performed.
--> See "Adjusting the Electrical Offset (Drift Adjustment)" on page 20 – 346.
When exchanging mechanical components, a new adjustment of the control loops of
axes and spindle may be necessary. --> Contact the machine manufacturer!
For information on the exchange of drive components, refer to the Service Manual "Inverter
Systems and Motors".
Exchange cables only for original cables! Do not exceed any maximum lengths!
If required, ensure a clean shielding and grounding of cables and components.
If possible, use original packagings from HEIDENHAIN.
Note
If you have any questions, contact the machine manufacturer or a HEIDENHAIN service
agency.
