GE Industrial Solutions AF-650 GP General Purpose Drive (460_575_690V 125HP and above) - Manual (Page 79)

F-16 Motor Speed Low Limit [Hz]
Range: Function:
0 Hz* [0.0 - par. H-14 Hz] Enter the minimum limit for motor speed. The Motor Speed Low Limit can be set to correspond to the
minimum output frequency of the motor shaft. The Motor Speed Low Limit must not exceed the setting
in par. F-15 Motor Speed High Limit (Hz).
F-17 Motor Speed High Limit [RPM]
Range: Function:
3600. RPM* [par. H-11 - 60000. RPM] Enter the maximum limit for motor speed. The Motor Speed High Limit can be set to correspond to the
manufacturer’s maximum rated motor speed. The Motor Speed High Limit must exceed the setting in
par. F-18 Motor Speed Low Limit [RPM].
NB!
Max. output frequency cannot exceed 10% of the inverter switching frequency (par. F-26 Motor Noise (Carrier Freq)).
F-18 Motor Speed Low Limit [RPM]
Range: Function:
0 RPM* [0 - par. H-13 RPM] Enter the minimum limit for motor speed. The Motor Speed Low Limit can be set to correspond to the
manufacturer’s recommended minimum motor speed. The Motor Speed Low Limit must not exceed the
setting in par. F-17 Motor Speed High Limit [RPM].
H-08 Reverse Lock
Option: Function:
Select the motor speed direction(s) required. Use this parameter to prevent unwanted reversing. When
par. H-40 Configuration Mode is set to Process [3], par. H-08 Reverse Lock is set to Clockwise [0] as default.
The setting in par. H-08 Reverse Lock does not limit options for setting par. F-15 Motor Speed High Limit
(Hz) or par. F-17 Motor Speed High Limit [RPM].
This parameter cannot be adjusted while the motor is running.
[0] * Clockwise
[1] Counter clockwise
[2] Both directions
P-04 Auto Tune
Option: Function:
The Auto Tune function optimises dynamic motor performance by automatically optimising the advanced
motor parameters (par. P-30 Stator Resistance (Rs) to par. P-35 Main Reactance (Xh)) at motor standstill.
Activate the Auto Tune function by pressing [Hand] after selecting [1] or [2]. See also the section Auto
Tuning in the AF-650 GP Design Guide. After a normal sequence, the display will read: "Press [OK] to finish
Auto Tune". After pressing the [OK] key the frequency converter is ready for operation.
This parameter cannot be adjusted while the motor is running.
[0] * Off
[1] Enable complete Auto Tune
[2] Enable reduced Auto Tune
Note:
• For the best results run Auto Tune on a cold motor.
• Auto Tune cannot be performed while the motor is running.
• Auto Tune cannot be performed on permanent magnet motors.
