4.4 Wiring notes
4.4.1 General
The wiring has to be done with regard to minimum cross sections, shields and earthings given.
Observe the presented branching conditions. If there are, for example, two parallel transmissions
starting from one point, it will not be admissible to lay only one transmission and to branch the one on
a later point, because induction loops (disturbance sender and aerials) as well as interfering potential
shift could develop.
ELAU as a system supplier provides the ready-made cables.
CAUTION
Minimum bending radius for all ELAU cables is 10 times the cable diameter
If no ELAU cables are used, please watch the following cross sections:

The following cables have to be separately laid and shielded:
• motor cable
• resolver cable
• encoder cable
• serial interface
Check the wiring before the switch on.
To avoid errors we recommend you to order the connecting cables together
with the PMC-2.
Frequent errors are:
• wrong shielding of transmissions
• frame or earth circuits
• change by mistake of the motor phases
• change by mistake of the resolver connections
