Run Motor Tune Routine
The drive can be tuned to the motor. Autotune routines can be accessed directly
or through the Start Up menu.
When tuning, it is preferred that the motor is uncoupled from the pump jack and
a Rotate Tune routine be performed. If this action is not possible, perform a Static
Tune routine.
Access Autotune Directly
1. Verify that the motor is turning in the forward direction by jogging the
motor. Rotation should be clockwise facing the shaft. If necessary, correct
direction of rotation by one of the following methods.
a. Swap any two motor leads. This method is recommended to help avoid
confusion later.
b. Change the motor direction by configuring drive firmware.
2. Once direction is established, enter the Rotate Tune parameter setting.
3. Press Start and allow the drive to complete the Autotune routine.
When complete, the motor can now be coupled to the pump jack.
Access Autotune Through Start Up Menu
1. Using the Human Interface Module (HIM), press the (Folders) key
to navigate to the Start Up tab.
2. Select General Startup and answer the questions when prompted.
When complete, the motor can be coupled to the pump jack.
ATTENTION: Rotation of the motor in an undesired direction can occur during
this procedure. To guard against possible injury and/or equipment damage, it is
recommended ti disconnect the motor from the load before proceeding.
