4.1 Overcurrent protection
Protect the components against overcurrent:
● Branch circuit protection has to be provided externally.
For the North American sales region, individual branch circuit protection
on the mains side is mandatory before each device.
● Dimension the branch circuit protection according to the "Branch circuit
protection fuse" data (see Ratings and dimensions)
Lethal electric shock from live parts with more
than 50 V!
Risk of burns by hot housing surfaces! Risk
of fire!
The opening of the branch-circuit protective device may be an indication that
a fault current has been interrupted. To reduce the risk of fire or electric
shock, current-carrying parts and other components of the controller should
be examined and replaced if damaged. If burnout of the current element of
an overload relay occurs, the complete overload relay must be replaced.
4.2 Connection
4.2.1 General information
Apart from the indicated connections, it is necessary to wire the
Bb contact at the control section for signaling the readiness for
operation of the drive controller (see Project Planning Manual
"Rexroth IndraDrive Drive Controllers Control Sections").
For proper function of the motor thermal management connect the motor
thermal sensor as described in the wiring diagram. Otherwise motor overtem‐
perature sensing is not provided by the drive.
For Rexroth motors with data memory in the motor encoder, such as MSK,
the motor overload protection level is set automatically while connecting the
motor to the drive. There is no adjustment necessary. Otherwise refer to the
Rexroth firmware documentation.
