Fitting Housing Cover
Before mounting the housing cover onto the servo motor, check that the cams of the end stop
microswitches have been correctly adjusted and the connecting leads are correctly screwed tightly in
the terminals.
Check whether the actuating element is totally closed when the controller signals the corre-
sponding end stop.
Ensure that the leads are not pinched between the housing and the housing cover and the circumfer-
ential rubber sealing ring in the housing is not damaged and is correctly seated in the groove.
Screw the housing cover tight using the two housing cover screws.
Commissioning
Before commissioning the servo motor the Safety Information on Page 2 and Safety advice in
Section 2 must have been read.
Switch on the power supply to the servo motor.
Drive the servo motor via the controller or by hand and check the correct functioning of the servo
motor, the microswitches and of the actuating element.
