Additional Adjustment
Tuning (Magnetek)
The Magnetek drive may require additional tuning to the motor:
Tuning Motor No-Load Current (HPV 600/900/900II)
1. To perform this procedure you will need to run the car at reduced speed with a balanced
load. Motor torque should be below 15%.
• Motor Torque, Flux Reference, and Est No Load Curr can be viewed on the drive D2
Power Data menu.
• No Load Curr can be adjusted on the drive A5 Motor menu.
• The car maximum speed can be changed via High Speed on the controller F7 menu,
150. (F7, 149, Contract Speed is used to set the rated speed for the car.)
2. Refer to Tuning No-Load Motor Current in the appendix of the Magnetek HPV AC Drive
Technical Manual and follow that procedure.
Tuning Motor Flux Saturation Curve (HPV 600/900/900II)
1. To perform this procedure you will need to run the car at full contract speed with a bal-
anced load.
• Est No Load Curr can be viewed on the drive D2 Power Data menu.
• No Load Curr and Flux Sat Slope 2 can be adjusted on the drive A5 Motor menu.
2. Refer to Tuning Rated Motor RPM in the appendix of the Magnetek HPV AC Drive
Technical Manual and follow that procedure.
Tuning Motor Rated RPM (HPV 600/900/900II) Please see Tuning Motor
Rated RPM in the appendix of the Magnetek HPV AC Drive Technical manual and follow that
procedure.
Determining System Inertia (All Magnetek)
In order to properly tune the speed regulator of the Magnetek drive, a valid inertia value must
be determined.
1. To perform this procedure, you will need to run the car at full contract speed with a bal-
anced load.
• Est Inertia can be viewed on the drive D1 Elevator Data menu.
• Inertia can be adjusted on the drive A1 Drive menu.
2. Refer to Using the Software to Estimate the System’s Inertia in the appendix of the Mag-
netek HPV AC Drive Technical Manual and follow that procedure.
3. With system inertia properly adjusted, final tuning of the speed regulator can be per-
formed. The Response parameter on the drive A1 Drive Menu is one parameter that can
be used to adjust the speed regulator. Please see the Magnetek HPV AC Drive Technical
Manual for tuning/adjustment procedures.
