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 EN 61800-5-1.
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.

Others Both channels potential-free, so that 24 V and 0
V can be connected.
Inputs designed for safety switchgear with test
pulses (OSSD). Signals are not evaluated, only
filtered. OSSD test interval is limited to 10 ms.
STO with OSSD signals The input voltage determines the maximum pulse width of the OSSD signals.

4.3.3 Voltage input
The control board is supplied
• externally by a central 24V supply.
To select a suitable voltage source, the maximum current consumption must al-
ways be determined.
4.3.3.1 Determination of the current consumption
The input P24Vin (X2B.8) supplies following components:
• Control (control board with safety functions)
• Driver/power unit
• Brake
• Encoder
Consumer Current consumption
Control 0.5 A
Power unit 0,8 A
Consumer Brake Max. 2.0 A
Encoder Max. 0.5 A
Digital output DO1 Max. 0.1 A
Digital output DO2 Max. 0.1 A
Voltage output 24Vout Max. 0.1 A
