Requirements to the motor cable
The maximum admissible length of the motor cable is 100 m. The capacity must not ex-
ceed 5.2 nF.
Example: If the cable capacity is 0.26 nF per meter, the maximum admissible length of
the motor cable is 20 m.
11.2.2
Communication Cables
Please connect the communication interfaces only with high-quality cables according to
the relevant standards.
Ungrounded test setups
→
So-called "flying test systems" that are not or not sufficiently grounded can cause
damage to the communication interfaces or to the connected devices.
RJ45
Use only high-quality RJ45 cables.
Low priced RJ45 cables can damage the female RJ45 connector. The dimensions of
the cable connectors deviate frequently from the standard dimensions. Thus, they cause
problems with the electrical contact after only few connecting cycles.
11.2.3
Cables for the Rotor Position Detection
Use shielded lines and shielded D-sub shells for wiring the different measuring systems.
Connect the cable shield to both connector shells: At the drive connect the shield to the
D-sub shell and at the motor to the shell of the measuring system connector.
