29 – 552 HEIDENHAIN Service Manual iTNC 530 HSCI
29.11 Exchanging other HEIDENHAIN components
HSCI components When you exchange HEIDENHAIN components of the iTNC 530 HSCI, messages related to
firmware or hardware updates may be issued.
8 Accept these changes.
--> See ”Recognizing and accepting hardware updates” on page 29 – 523.
8 Run the required firmware updates.
--> See ”Detecting and loading firmware updates” on page 29 – 524.
Encoders Many HEIDENHAIN products (encoders, scanning heads, etc.) are supplied with mounting aids
(metal forks, spacer plates, etc.)
Mounting Instructions and Mounting Information are also included in delivery.
The HEIDENHAIN testing devices PWM 9 (See ”PWM 9 encoder diagnostic kit” on page 30 – 564)
or PWT (See ”PWT 10/17/18 test unit” on page 30 – 566) are good aids for adjusting scanning
heads.
When HEIDENHAIN encoders (e.g. linear encoders) are exchanged, in most cases the
machine datum needs to be reset. --> See ”Encoder interface” on page 19 – 277.
If a HEIDENHAIN motor encoder for a spindle was exchanged, it may be necessary to
reset the spindle preset. --> See ”Encoder interface” on page 19 – 277.
Drive components
and mechanics
If HEIDENHAIN motors for axes or spindles were exchanged, it may be necessary to readjust the
trip dog for reference end position, to reset the machine datum and to determine the spindle preset.
--> See ”Encoder interface” on page 19 – 277.
Some successor models (e.g., inverters, motors) are supplied with replacing instructions
describing, e.g., changes required in the MP list or in motor or power module tables.
When you exchange electrical original components (inverters, motors, etc.) normally no
readjustment of the control loops of axes and spindle is required.
Exception: When exchanging a CMA-H 04-04-00 additional module for analog axes and spindles,
an offset adjustment with the code number for fine compensation should be performed.
--> See ”Adjusting the electrical offset (drift adjustment)” on page 21 – 355.
For information on the exchange of drive components, refer to the Service Manual ”Inverter
Systems and Motors”.
When you exchange mechanical components, readjustment of the control loops of axes and
spindles may be necessary. --> Contact the machine manufacturer!
Cables Always use original HEIDENHAIN cables as replacements! Do not exceed any maximum lengths!
Shielding and
grounding
If required, ensure proper shielding and grounding of cables and components.
Packaging If possible, use the original HEIDENHAIN packaging.
When you exchange motors or encoders for drives that determine the field angle (normally linear
and torque motors) the function Field orientation must be executed again.
Contact your machine manufacturer!
