3-point standard operation

To protect elements such as gears and connecting elements against harmful effects due to control pulses that are too short ... Max rotary drives are protected through the internal electronics. The electronic system ignores impulses < 0.5 s. The control signal must be present for min. 0.5 s. For a directional change, the pause is 1 s.

Additional information for activation in 3-point operation

The direction of rotation for the motor depends on the positions of contacts a and b:

• contact a closed, contact b open = direction I
• contact a and b closed = motor does not turn
• contact b closed, contact a open = direction II
• contact a and b open = motor does not turn.

Example:

The direction of rotation (I and II) depends on the left/right installation of the rotary drive on the device. A motorised change to the direction of rotation is done by swapping the connecting wires 3 and 4.
