Changing the Output Direction of Power and Feedback Connectors
Power connectors
In case of the motors MHD041, MHD071, and MHD090, you can select
the output direction of the power connector when mounting these motors.
The flange sockets are designed such that they can be turned (angle of
rotation of 270 degrees).
Adjustment of the desired cable output direction is described below.
Note: Do not use any tools (e.g. tongs or pliers or screwdrivers) to
turn the motor flange socket. Mechanical damage to the flange
socket cannot be excluded.
The motor flange socket can be turned easily if an appropriate plug has
been connected. Owing to the leverage of the connected plug, the flange
socket can be turned manually to the desired output direction.
Proceed as follows:
1. Connect the motor power cable to the flange socket.
2. Put the flange socket to the desired output direction by turning the
connected plug.
The desired output direction is set.
Note: Whenever the flange socket is turned, the holding torque in
the set position is reduced. To ensure the required holding
torque of the flange socket, the cable output direction should
be changed no more than 5 times!
It is not necessary to “rebuild” the flange socket (i.e. dismounting and
mounting the flange socket, relocated by 90 degrees). The following
problems and risks can arise should the flange socket be “rebuilt”:
• The O-ring seal between the flange socket and the motor housing is
not ensured any longer.
• The tightening torques prescribed are, perhaps, not kept.
• The TFL coating (screw locking element) of the locking screws will
wear by unscrewing, thus becoming ineffective.
Note: No warranty!
If the cable output direction is changed by “rebuilding” the
flange socket, the warranty for the overall drive system
given by BOSCH REXROTH will expire. The cable output
direction may only be changed by turning the flange socket.
