Delem DAC-310 - Drive Types; Servo Drive

V1204, 2.8
2.3. Drive types
The DAC control can be programmed to drive different axis types:
• 1-speed AC or DC drive
• 2-speed AC or DC drive
• Servo motor drive
The required system can be programmed with the parameter ‘Drive type’.
2.3.1. Servo drive
The following servo parameters are valid:
• Servo gain
• Servo switch
• Servo Ramp
• Servo acceleration
Inside the switch zone the Gain is active and outside the switch zone the Ramp is active. See
the Axis parameters ‘Gain’, ‘Switch’ and ‘Ramp’.

The optimal values for these parameters can be found by the following procedure:
• Increase the Ramp (point by point) until the axis has overshoot at the programmed end
position, substract 1.0 from this value and program this for the Ramp.
• Increase the Gain (point by point) until the axis starts to oscillate at the programmed end
position, substract 1.0 from this value and program this for the Gain.
The Ramp should be smaller than the Gain.
