Adjusting the Controller Gain

During commissioning, you have to set the controller gain.

You have to set the gain for each guiding mode separately.

Adjusting the controller 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.
  • »The material web is pulled in and is tensioned.
  • »The guiding device is not in an end position.
  1. Select the desired guiding mode.
  • Guiding to the left web edge (Sensor 1):
  • Press the Sensor 1 key.
  • or
  • Guiding to the right web edge (Sensor 2):
  • Press the Sensor 2 key.
  • or
  • Web center-line guiding (Sensor 1 and Sensor 2):
  • Press the Sensor 1 and Sensor 2 keys at the same time.
  • or
  • Line / contrast / feature guiding (Sensor 3):
  • Press the Sensor 3 key.
  1. Press the Automatic key.
  • The LED of the key will illuminate.
  • The controller switches to automatic mode.
  1. Press the SETUP key.
  • The set gain is displayed at the bottom edge of the display using a bar indicator ① and as a numeric value ②. If the numerical value is displayed in blue, it can be adjusted using the arrow keys.
  1. Keep increasing the gain using the right arrow key until control oscillations occur (the guiding device starts to tremble).
  1. 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 5.0.
  1. Press the ENTER key.
  • The gain setting is complete.
If control oscillations do not occur we recommend setting the maximum gain.

When commissioning, the controller gain should be adjusted as described above, because the optimum gain value is still unknown. During operation, the controller gain can also be adjusted via the touchscreen function.

For setting the controller gain using the touchscreen function please refer to the operating manual ekr CON 600, ekr CON 600 net, document number MD.542.
