Learn or Enter Motor or Encoder Data
In order to enter motor nameplate data
into the drive, learn motor information, or learn encoder information, you must activate param-
eter LF.3 appropriately:
• conF (configuration): Operation troubleshooting (90 second time-out)
• S Lrn: Auto tuning drive to motor
• run: Sets drive to run mode
• I Lrn (inertia learn): Learns system inertial / activates FFTC.
• P Lrn (pole learn): Learns motor pole positions (see drive manual).
• StoP: Motor cannot run. Parameter changes allowed with serial control.
Note
When StoP is active, the drive will not respond to the direction inputs and therefore, the motor
will not run.
Auto-tuning AC Induction Motors to the F5 Drive
Auto-tuning provides better drive to motor matching and performance than manually entering
parameters. Before beginning, make sure that the following parameters have been loaded into
the drive:
• Rated Motor Power (horsepower) (LF.10)
• Rated Motor Speed (rpm) (LF.11)
• Rated Motor Current (A) (LF.12)
• Rated Motor Frequency (Hz) (LF.13)
• Rated Motor Voltage (LF.14)
• Rated Power Factor (LF.15) (not viewable for PMAC machines)
1. Verify the controller is on Inspection operation. Remove one brake wire from the con-
troller or reduce brake pick voltage level to prevent the brake from picking.
2. Reduce Inspection Speed F7, 155 to zero.
3. Set F7 parameter 141 Profile Scale to 000% (zero percent).
4. Set LF.3 to S Lrn. The display will change to StArt.
5. Hold the controller Enable button down and select the Up direction. The motor contac-
tor should engage but the brake should not pick. Motor current will begin to flow and
the drive display will change to LS103.
The drive will measure motor parameters as well as parameters in the drive motor stage. The
drive display will change as different values are measured.
6. Continue holding the Enable and Up direction switch until the drive displays “done”
(five minutes is typical).
7. Release the Enable and Up direction switches. The drive will display CALC and complete
updating its parameters.
8. Return the drive to Run mode (LF.3). Reconnect the brake wire. Return F7 parameter
141 Profile Scale to 100% and F7, 155 to its former setting.
If the auto-tune was not successful, the drive will report:
• FAIL: Auto-tuning was interrupted. Repeat the procedure.
• FAILd: There is a configuration error, probably an incorrectly set parameter, that is pre-
venting the drive from beginning measurements.
• Check connections and parameters.
