12 Connection System
12.1 Overview of Connections
The electric connections of Rexroth drives are standardized. The MKD
AC motors are provided with
•
a power connector, incl. connection for temperature sensor and
holding brake,
•
an encoder connection (feedback connector).
Both connections depend of the motor type, wether as connection box or
as a separate plug-in connector.

(1): Blower
blower units can be attached optionally on MKD motors. Blower units
are working independent from the drive controller. Blower cables and
protective circuit breakers are not in the scope of delivery of REXROTH
INDRAMAT.
(2): Temperature sensors
Temperature sensors (PTC) are fixed-mounted in the motor windings.
The measurement data evaluation is occured over the drive controller.
(3): Holding brake
The optional holding brake can be triggered over an external control
(SPS) or with an appropriate drive controller.
(4): Power connector
Standard version as connector box, on motor type 112 as plug-in
connector. For type 025 connectors can also be delivered alternatively.
(5): Encoder connection
Standard version as connector box, on motor type 112 as plug-in
connector. For type 025 connectors can also be delivered alternatively.
