9910 MOTOR ID RUN
This parameter controls a self-calibration process called the Motor Id
Run. During this process, the drive operates the motor in order to
identify it's characteristics, and then optimizes control by creating a
motor model. This motor model is especially effective when:
• Operation point is near zero speed.
• Operation requires a torque range above the motor nominal torque,
over a wide speed range, and without any measured speed feedback
(i.e. without a pulse encoder).
If no Motor Id Run is performed, the drive uses a less detailed motor
model created when the drive is first run. This "First Start" model is
updated automatically* after any motor parameter is changed. To
update the model, the drive magnetizes the motor for 10 to 15 seconds
at zero speed.
*Creating the "First Start model does require that either 9904 = 1
