Observe the following instructions to avoid malfunctions!
• Install control and power cable separately (approx. 10..20 cm (4"..8") distance).
• Cross high voltage conductors at a 90-degree right angle.
• In case of inductive load on the relay outputs, a protective device must be
provided (e.g. free-wheeling diode).
• Electromagnetic interference can be prevented by the following measures:
– Always use twisted and shielded cables for analog control cables. Place
the shield on one side of the source.
– Twist digital control cables. For lengths longer than 3 m (10'), a shield may
be required. In this case connect the shield at both ends.
– When the brake conductors or motor temperature sensor conductors are
run together with the motor conductors, the brake and temperature con-
ductors should be shielded. The shield of the brake and temperature
sensor conductors should be connected to earth ground together with the
motor conductor shield. The shields should be kept as long as possible to
prevent cross coupling with the motor conductors.
The terminals of the control terminal blocks, encoder inputs and the communication
interface are securely isolated in accordance with
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.
