CAUTION
For the connection between drive controller and motor, use Rexroth motor
Cable power cables.
The Rexroth motor power cable comprises
• three conductors for motor power connection
• one conductor for equipment grounding connection
• a separately shielded pair of conductors for motor temperature
monitoring
• a separately shielded pair of conductors for motor holding brake
• an overall shield to be applied to shield contact.
Alternatively the cable can be composed of four twisted single wires
(3 phases, 1 equipment grounding conductor) with separately guided,
shielded wires for temperature monitoring and connecting the brake.
Note: For more details on the technical data, connection and cross
section, please refer to the respective motor description.
To avoid overload of the drive controller the motor cable length is limited
at a switching frequency > 4 kHz.
The lengths indicated in the table below are recommended as guide
values (at an ambient temperature of ≤ 40 °C in accordance with
EN 60 204).
Allowed line lengths for motor connection without filter measures at
motor output:

Damage to the drive controller!
⇒ Strain relief for the motor power cables cannot be
provided at the drive controller. Therefore, make
sure strain relief of the motor power cables is
provided in the control cabinet.
