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 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
( : ), or 9904 = 3 (

Note: Motor models work with internal parameters and user-defined
motor parameters. In creating a model the drive does not change any
user-defined parameters.

TORQ BOOST
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
MINIMUM SPEED
• 2002
MAXIMUM SPEED
rated speed.
SCALAR
• 2003
MAX CURRENT
• The maximum torque (parameters 2014,
2017 and/or 2018) > 50%.
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.
