Notes on Installation
Make sure the voltage supply for the motor holding at the motor
brake is sufficient. You have to take into account that voltage
drops on the supply line. Use connecting lines with the highest
possible cross section of the single strands.
An external contact element is required, if motor holding brakes
with higher currents than the allowed current load are to be sup‐
plied at X6.
Coding of the Connectors
At the HMD power sections with two inverter outputs, the outputs
have been coded, i.e. provided with a coding section. This avoids
accidentally interchanging the two cables.
Coding
● X6.1: Coding section at pin 4
● X6.2: Coding section at pin 1
For ready-made Rexroth motor power cables, you therefore have
to code the male connector at the motor power cable accordingly
for X6.1 and X6.2:
● For connector X6.1: Cut off plastic pin 4 at connector
● For connector X6.2: Cut off plastic pin 1 at connector
