Process values and parameters

GMA161.1E/MO

All process values (setpoints and actual values) and all parameters are implemented as Modbus RTU registers.

Self-adaption of the rotary angle range

GMA161.1E/MO

The actuator automatically determines the effective rotary angle range when the respective parameter is set to “on”. In that case the actuator performs a calibration run at first startup to determine its actual opening range and adjusts the 0..100% feedback signal to this opening range.

The table shows the different effects of the characteristic function’s mapping to the rotary angle range for “inactive self-adaptation” and “active self-adaption”:

Inactive self-adaption Active self-adaption
  • The actuator calibrates the position indication with Actual Position = 0..100% for rotary angle = 90°

  • The actuator calibrates the position indication with Actual Position = 0..100% for rotary angle < 90°
