NOTE!
•
For the best results of the adjustable frequency
drive, run Auto Tune on a cold motor
•
Auto Tune cannot be performed while the motor
is running.
NOTE!
Avoid generating external torque during Auto Tune.
NOTE!
If one of the settings in parameter group P-## Motor Data
is changed,
1-30 Stator Resistance (Rs)
to
1-39 Motor Poles
,
the advanced motor parameters will return to default
setting.
This parameter cannot be adjusted while the motor is
running.
NOTE!
Full Auto Tune should be run without filter only while
reduced Auto Tune should be run with filter.

Enter the initial ramp-up time from zero
speed to Motor Speed Low Limit,
or

Low Limit [Hz]
. Submersible deep well pumps
can be damaged by running below minimum
speed. A fast ramp time below minimum
pump speed is recommended. This parameter
may be applied as a fast ramp rate from zero
speed to Motor Speed Low Limit.
