Change the Orientation of the Connectors
MP-Series motors use two styles of connectors. The connector style is identified by a 2 or a 7 as
the connector variable in the motor catalog number. For example, MP
x-xxxxx-xx2xxx or
MP x-xxxxx-xx7xxx:
•
A 2 indicates a circular bayonet connector, facing the shaft.
•
A 7 indicates a circular DIN, right angle, rotatable connector.
The sections below describe acceptable methods for rotating the connector orientation for these
connector styles.
Reversible Connector Facing the Shaft (catalog number MPL-xxxxx-xx2xxx)
This connector housing can be reversed to face down when the motor is installed in a vertical
application, or rearward if connector access is restricted in a horizontal application. Follow these
steps to remount the connector housing.
1. Remove the three connector housing screws from the motor.
2. Rotate connector housing 180°.
If binding of the wire bundles prevents rotation of the connector, you can gain access to
the internal motor wiring by following these steps.
a. Remove the four screws from the rear cover of the motor.
b. Carefully reposition the wires around the perimeter of the motor feedback device
under the rear cover.
c. Be sure that the wires are not close to any rotating parts.
3. Reinstall the connector housing and torque the three screws to 0.8…1.0 N•m
(7…9 lb•in) after verifying that gaskets are properly positioned, and that no wires are
pinched under the connector housing.
4. Reinstall the four rear cover screws and torque them to 0.8…1.0 N•m (7…9 lb•in) after
verifying that the rear cover O-ring is properly positioned onto the rear cover circular
pilot surface.
ATTENTION: Do not loosen or remove the motor feedback device (encoder) mounting screws while
repositioning the connector wires.
Encoder alignment is a critical adjustment that can be performed only in the factory. An incorrect
adjustment can render the motor inoperable or degrade motor performance, and voids the motor
warranty.
ATTENTION: Do not damage the screw holes when reinserting the self-tapping screws holding the
connector housing and rear cover.
Excessive force can strip the threads within the screw holes and prevent proper sealing of the motor.
Do not exceed the specified torque values.
