Motor connection
Motor:
Fig. 5-55:
Motor connections
Use Rexroth Indramat motor power cables to connect motor and
Cable
controller.
Motor:
Note:
For technical data on connections and cross sections, see the
motor project planning manual.
Cable length:
Maximum length equals 35 m:
•
With two connections between controller and motor
(e.g., plugs at exit of control cabinet and at machine)
•
Standard cables from Rexroth Indramat and
•
Ambient temperatures of ≤ 40 °C per EN 60 204
•
Switch frequency of 4 kHz
Maximum allowed capacitance per unit length at A1, A2, A3:
•
with regard to ground: 0.5 nF/m
•
cable to cable: 0.5 nF/m
Maximum allowed inductance per unit length an A1, A2, A3:
•
100 nH/m
To maintain EMC values, the motor cable length is limited with a
switching frequency of > 4 kHz. It is largely dependent on the application
and ambient conditions at the installation and machine.
A guide value is listed below:
Cycle frequency drive
controller
standard setting switching
frequency 4 kHz
parameter setting switching
frequency 8 kHz
