MOTOR ID RUN
0, 1

0
9
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 (
VECTOR
:
SPEED
), or 9904 = 3 (
SCALAR
:
FREQ
)
and 2101 = 3 (
SCALAR
FLYSTART
) or 5 (
FLYSTART
+
TORQ
BOOST
).
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.
0 =
OFF
– Disables the Motor Id Run creation process. (Does
not disable the operation of a motor model.)
1 =
ON
– Enables a Motor Id Run at the next start command.
After run completion, this value automatically changes to
0.
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
< 0
• 2002
MAXIMUM
SPEED
> 80% of motor rated speed.
• 2003

value.
• The maximum torque (parameters 2014, 2017 and/
or 2018) > 50%.
