Step Action Comment
1.
Specify the cable cross-section depend-
ent on the maximum current and ambient
temperature.
Cable cross-section according
to local and country-specific
regulations and conditions
2.
Connect the shielded motor cable to ter-
minals X1/ U, V, W and connect the motor
to ground at .
Mount shield at both ends to
reduce interference emission.
3.
Wire the motor temperature sensor and
activate temperature evaluation by means
of DriveManager. See also related note.
Mount shield at both ends to
reduce interference emission.
Motor temperature sensor
ATTENTION! When connected to terminal X4, the motor must provide
reinforced insulation in accordance with EN 61800-5-1.
X4 Temperature switch (Klixon), PTC, KTY Sensor with increased insulation

NOTE: In the event of a short-circuit or ground fault in the motor cable, the
power stage is disabled and an error message is issued.

NOTES:
• The usage of encoders not included in the range supplied by KEBA
requires special approval by KEBA.
• X4a the maximun signal input frequency is 500kHz.
• X4b the maximun signal input frequency is 2MHz (for TTL only).
• Encoders with a power supply of 5 V ± 5 % must have a separate sensor
cable connection. The encoder cable detects the actual supply voltage at
the encoder, thereby compensating for the voltage drop on the cable. Only
use of the sensor cable ensures that the encoder is supplied with the cor-
rect voltage. The sensor cable must always be connected.
Select the cable type specified by the motor or encoder manufacturer. During this pro-
cess bear in mind the following:
• Always used shielded cables. Apply the shield on both sides.
• Connect the differential track signals A/B, R or CLK, DATA to each other
via twisted wires.
• Do not split the encoder cable , for example to route the signals via
terminals in the switch cabinet.
