01 MOL
Indicates which fault is shown (1-5)
(1 denotes the most recent fault)
In addition to the active faults, the drive maintains a history of faults. The 5 most recent faults are kept in
the fault history log.
5.7.2 Jog Control
Press the Jog button to enter Jog mode. The green Jog indicator in the key illuminates when the drive is
in Jog mode. To jog the motor in either direction, press and hold either the FWD or REV. The motor will
operate at the frequency programmed in parameter I/O 12 - Jog Speed. To exit Jog mode, press Jog again.
z NOTE: Must be set to LOCal. Press the “loc/rem” key if you are in REMote mode. See page 54 for
more information on control modes.
5.7.3 Measuring Stator Resistance (RS Measurement) for Vector Control
Make sure there is no load applied to the motor and that the motor shaft is free to spin without damage. •
Set the following parameters to the data on nameplate of motor: FUN 01 - Nom Mtr Volt, DRV 01 - •
Nom Mtr Amps, AFN 02 - Nom Mtr RPM, AFN 12 - Power Factor.
Change parameter AFN 11 (Auto-tune) to “Motor RS”. At this point, the RS measurement will be •
armed.
The operate screen shows in two ways that an RS Measurement is ready to be made. First, the Control •
path status eld displays “MEA”. Second, a “Mtr Measure” warning ashes.
Start the RS Measurement by pressing the “FWD”. •
The measurement will begin as the drive injects voltage to the motor at zero freq. This lasts 2 seconds. •
If the test was successful, AFN 10 - Motor RS will contain the new Motor RS. •
If the tests fails, you may want to try the test again with a different “Rated Mtr FLA” or •
Current Limit %.
5.7.1 Active Fault / Warning and Fault History Mode
When a fault or warning occurs, the Operate mode automatically changes to the Active Fault mode. The
drive stores up to 5 active faults or warnings, and provides a separate display for each.
Once the active fault display is shown, you must correct the condition causing the fault and then reset the
drive to return to the Operate mode.
