6.4.1.4 Optimising phase controller

How to optimise the phase controller setting by means of the ramp response:
1. Run a typical speed profile and record the ramp response of the phase controller with the
Oscilloscope . ( 611)
• Motor control variables to be recorded:
Speed.dnSpeedSetpoint (speed setpoint)
Speed.dnActualMotorSpeed (actual speed value)
Speed.dnOutputPosCtrl (phase controller output)
Position.dnEncounteringError (following error)
2. Adjust the gain Vp of the phase controller under C00254 and repeat oscilloscope recording
until the intended following error behaviour is reached and the motor runs sufficiently
smoothly during the constant travel phase.
3. Save parameter set ( C00002 = "11: Save start parameters").
