Function
Shifts when the torque command is bigger than P control shift reference
value (%).
Shifts when the speed command is bigger than P control shift reference
value (RPM).
Shifts when the position error is bigger than P control shift reference
(pulse).
Please set the P control shift reference for a torque
command at SEt-55. The setting range is 0 to 300%
and the default value is 100.
Please set the P control shift reference for a speed
command at SEt-56. The setting range is 0 to 3000
RPM and the default value is 100.
Please set the P control shift reference for a
position error at SEt-57. The setting range is 0 to
10000 pulse and the default value is 100.
The picture below shows the speed response when the speed
regulator is changed from PI to P by torque command in the transient
response status.
In the transient status of acceleration area or deceleration area, if the
torque command is bigger than the P/PI mode shift reference, the
speed regulator will be P type and PI controller type in other areas.
ATTENTION
/P-CON signal will be shifted prior to P control shift switch
and the reference set-up. In other words, regardless of the
current motor status and the set-up of these values, the speed
regulator will be P controller type if /P-CON signal is ON.
To reduce the position completion time or overshoot of the
speed response by using this function, P control shift switch
and the reference should be set up properly. Please closely
watch transient responses of speed, torque, and position for
optimum set-up.
