Rexroth IndraDrive Mounting and Installation 6-45
DOK-INDRV*-FU*********-IB01-EN-P
For the connection between drive controller and motor, use Rexroth motor
power cables (see documentation "Rexroth Connection Cables; Selection
Data", DOK-CONNEC-CABLE*STAND-AUxx-EN-P).
CAUTION
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 or cable use our
special accessories HAS02.1.
Connection of Motor Cable to Drive Controller
There are the following minimum requirements for connecting the motor
cables to the drive controller:
• Connect the shield of the motor cable over the largest possible
surface area (with low impedance) to the drive controller. The
connection of cable shields by means of round wires (so-called "pig
tails") at the cable ends to ground and housing is normally insufficient.
• Make sure there is sufficient strain relief for the motor cable itself.
Optional accessory HAS02 to be used with connection over a large
surface area directly to the device. This is the best solution. The figure
below illustrates this by the example of HCS02 drive controllers:

Fig. 6-57: Connecting HAS02 to HCS02
For shield connection without HAS02 accessory connect the cable shield
with the lowest possible impedance to the drive controller.
The following paragraphs describe two basic alternatives of this kind of
connection.
