4 Connection of the control
Observe the following instructions to avoid malfunctions!
• Install control cables and power cables separately (approx. 10…20 cm distance);
Lay crossings in a right angle.
• In case of inductive load on the relay outputs a protective wiring must be
provided (e.g. free-wheeling diode).
• Electro magnetic interferences can be prevented by the following measures:
– Always use twisted and shielded cables for analog control lines. Connect
the shield at one side at the signal source.
– Twist digital control cables. Up from 3 m a shield may be required. In this
case connect the shield at both ends.
– Connect the shield of the brake and temperature monitoring together with
the motor shield. Leave the inner shields longer in order to avoid interfer-
ence coupling or decoupling (the latter during temperature measurement)
as far as possible.
The terminals of the control terminal block, enocder inputs and communication in-
terface are securely isolated in accordance with
4.1 Assembly of wires
ACHTUNG
Loose and slack cable connections!
Malfunctions due to loose contacts.
a) Observe metal sleeve length and stripping length according to table.
b) Use a suitable pressing tool.
c) Make sure that all wires are inserted into the wire-end sleeve.
d) After inserting the cable into the terminal, check that it is firmly seated.
