1. Unscrew the screws of the servomotor hood, and remove the
hood.
2. Establish electrical connections according to the diagram
shown in fig.
– Connect terminals 18, 19 and 20 in accordance with
requirements; voltage < 50 V.
3. Determine the direction of rotation and correct it, if necessary.
Determining the direction of rotation
According to the internal wiring, the direction of rotation (looking
through the drive towards the output shaft) and limit switches are
assigned as follows:
• If mains voltage is present at terminal 2, the output shaft
rotates counter-clockwise (direction open/max.).
– This direction of rotation is restricted by the upper switch
(max.). If the switch is activated, the mains voltage is
present at terminal 4.
• If mains voltage is present at terminal 3, the output shaft
rotates clockwise (direction close/min.).
– This direction of rotation is restricted by the lower switch
(min.). If the switch is activated, the mains voltage is present
at terminal 5.
• If the drive rotates in the opposite direction to the control
commands, swap over the connections of terminals 2 and 3.
4. Close the hood again and tighten the hood screws.
