Application Notes C-3
Initial Static Auto Tune Test
1. Set the following parameters as shown.
2. Press the Start key on the HIM. Parameters 062-064 will be updated.
Motor Rotation/Encoder Direction Test
3. Set the following parameters as shown.
Important: If the direction of travel is critical at this point, perform
short jogs to determine which run direction (RUNFWD
or RUNREV) should be used in the next steps.
4. Press Start and run the drive in the desired direction. Observe the
direction of motor rotation.
If rotation is not in the desired direction:
– remove drive power and reverse the two motor leads, or . . .
– set bit 5 of [Compensation], parameter 56 to “Mtr Lead Rev.”
5. With the drive running, observe [Encoder Speed], parameter 415. If
the sign of the encoder is not the same as the displayed frequency,
remove drive power and reverse encoder leads A and A NOT.
6. With the drive running, verify correct motor rotation and encoder
direction. Set [Motor Fdbk Type], parameter 412 to “1, Quad
Check.” Stop the drive.

ATTENTION: To guard against personal injury and/or equipment
damage caused by unexpected brake release, verify Digital Out 1 brake
connections and/or programming. The default
drive configuration
energizes the Digital Out 1 relay when power is applied to the drive. If
the brake is connected to this relay, it could be released. If necessary,
disconnect the relay output until wiring/programming can be verified.
