// Here we use 'real encoder with direct PWM'. Further the axis are scaled
|
|
// in this configuration, the PID gives 'torque' to iqCmd.
|
|
// the phasePos is received from tne encoder on the motor shaft.
|
|
// The idCmd is set to 0
|
|
// the PID regulates the position by setting torque, if the motor is not at the desired position
|
|
// Compared to 'real encoder with direct microstepping', following main elements have to be reconfigured:
|
|
// SlipGain=0 (instead 0.25) ,PhasePosSf= calculated value (instead of 0)
|
|
// look also at PwmSf,PhaseMode,PhaseCtrl,
