9908 MOTOR NOM SPEED
Defines the nominal motor speed.
• Must equal the value on the motor rating plate.
9909 MOTOR NOM POWER
Defines the nominal motor power.
• Must equal the value on the motor rating plate.
9910 MOTOR ID RUN
This parameter controls a self-calibration process called the Motor ID
Run. During this process, the drive operates the motor and makes
measurements in order to identify motor characteristics and create a
model used for internal calculations. An ID Run 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).
First Start. If no Motor ID Run is performed, the drive estimates motor
characteristics when the drive is first run. This "First Start" occurs
automatically* at the next run command after any motor parameter is
changed. In order to estimate characteristics and create a motor model,
the First Start magnetizes the motor for 10 to 15 seconds at zero speed.
* Activating the "First Start" does require that:
• 9904 = 1 (

repeat the Motor ID Run.

To perform a Motor ID Run:
1. De-couple load from motor (or otherwise
reduce load to near zero).
2. Verify that motor operation is safe:
• The run automatically operates the
motor in the forward direction – confirm
that forward rotation is safe.
• The run automatically operates the
motor at 50...80% of nominal speed –
confirm that operation at these speeds is
safe.
3. Check following parameters (if changed
from factory settings):
• 2001

4. At the Control Panel, select:
• Select Parameters
• Select Group 99
• Select Parameter 9910
• Set value to 1 and press Enter – The
display shows a warning.
• Press START – The display shows the
progress of the run.
Note! Pressing STOP, or removing the run
enable signal stops the ID Run. In this
case you'll need to repeat the Motor ID
Run to create the motor model.
