28 – 492 HEIDENHAIN Service Manual iTNC 530 HSCI
Wiring overview CMA-H 04-04-00: Schematic wiring diagram
Please note:
Connect the shield of the connecting cable leading to the nominal-value output both to
pin 3 a/b on the CMA-H and to the ground potential of the housing of the CC 61xx or UEC 11x.
HEIDENHAIN recommends using EMC shielding terminals. The max. distance between the
CMA-H and the ground point is 500 mm.
On the analog servo amplifier, you also connect the shield of the connecting cable to the ground
potential of the housing via an EMC shielding terminal.
Use only shielded twisted-pair connecting cables.
The connecting cables to the nominal-value outputs must not have more than one intermediate
terminal.
