NOTICE
The motors described here can only be operated with suitable drive control‐
lers with variable output voltage and frequency (converter mode) as specified
by Rexroth.
System functionality and operational reliability are only ensured when
Rexroth components are used. Rexroth offers a wide range of ready-made
cables and connectors which are optimally adapted to match the products
and meet a variety of requirements.
The power wire cross-section was rated for cables by current carrying capaci‐
ty according to VDE 0298-4 and laying type B2 according to EN 60204-1 at
an ambient temperature of 40 °C.
Significant advantages of Rexroth's ready-made cables are:
● Ready-for-connection without any additional finishing
● Designed for continuous alternating bending stress
● Resistant against mineral oil, grease and bio-oil, silicone- and halogen-
free, low-adhesion
● Use of cables approved according to UL and CSA
● Flammability complies with VDE 0472-804 requirements
● Compliance with the EMC directives
● Degree of protection up to IP67
Power cables and connectors are not in the scope of delivery of the motors.
They have to be ordered separately.
Additional information:
● on how to select power and encoder cables can be found in the docu‐
mentation "Rexroth Connection Cables", MNR R911322948 (DE) and
MNR R911322949 (EN);
● can be found in the documentation "Electromagnetic Compatibility
(EMC) ..." MNR R911259740.
The motors are connected to power on their upper side. Design optionally
uses
● device connector or
● Terminal box
Please also observe the information in the type code of the particular motor.
