● Speed loop PI/P switching
Five switching modes in total are available for PI/P switching:
– using torque setpoint
– using an external digital input signal (G-CHANGE)
– using speed setpoint
– using acceleration setpoint
– using pulse deviation
If you select either of the PI/P switching modes (except the second mode), you need to
set the conditional threshold as shown in the above screenshot.
