Installation
4.3.3 Optional absolute encoder 0...10 V
The integrated absolute encoder supplies information about the position of the
connecting rod. The encoder is a contact-free absolute multiturn measuring
system. As soon as voltage is applied to the encoder it sends a secure voltage
signal that corresponds with the position of the connecting rod. An output of
0 - 10 V for entire length of the stroke is standard. On request the minimum
value and also the maximum value can be factory-set to other values (up to
14 V)
Calibration of the encoder
If the encoder has been demounted from the drive, it must be recalibrated after
being reinstalled correctly. Proceed as follows:
1. Traverse drive to the exact centre of its stroke.
2. Remove the small rubber stopper from the cover of the encoder.
3. Insert a suitable rod 2 - 3 mm in diameter with a blunt end through the hole
and press and hold the button in the hole for >3 s.
4. Check the voltage value at the analogue output; it must be equivalent to the
average value of the working range (generally 5 V).
5. Replace the rubber stopper in the hole in the cover.
The parameters required for operation are listed in the following tables.
All values are based on an ambient temperature of 20 °C:
