have to set its gain.

Setting the gain
WARNING
Danger of death from actuator movements!
During function tests, parts of your body may be crushed, cut or hit.
►
Make sure that no persons remain in the vicinity of the pivot /
traversing area of machine components that are positioned by
the actuator.
1. Press the Center positioning key.
The LED of the key will illuminate.
The guiding device moves to its central position.
2. Press the SETUP key.
The set gain of the servo center transducer is displayed at the
bottom edge of the display using a bar indicator ① and as a
numeric value ②.
3. Keep increasing the gain using the right arrow key until control
oscillations occur (the guiding device starts to tremble).
4. Keep reducing the gain using the left arrow key until the
oscillation ceases (stable guiding operation).
If you desire a slower reaction of the control, you can reduce
the gain even further.
Pressing both arrow keys at the same time will reset the gain to
a value of 20.0.
5. Press the ENTER key.
ð The gain setting is complete.
After a pre-set time (Timeout) has elapsed after pressing
the key for the last time, the display of the gain is auto-
matically faded out.
If control oscillations do not occur we recommend setting
the maximum gain.
