Chapter 4 Configure and Start Up the Drive
Direction Verification
The direction verification procedure can be performed with or without the
load attached. Consider your application requirements when deciding to have
the load attached or removed from the motor. The procedure confirms motor
rotation and feedback polarity.
After the procedure is complete, a change can be made, if necessary.
1. On the Parameters page, change the selection to 0-PowerFlex |
Feedback | Show Non-Defaults, so that the encoder direction can be
observed.
2. Use a Logix controller or HIM to jog the drive and observe the direction
of the motor in 00:131 [Active Vel Fdbk].
3. Compare the direction to the encoder direction in 00:130 [Alt Vel
Feedback].
4. If they match as shown, you do not have to change the electrical
direction of the encoder.
ATTENTION: If the drive was never operated before (new installation), verify
that safeguards are in place to remove power safely from the drive during an
unstable situation where the drive can produce undesired motion.
ATTENTION: This procedure causes movement of the motor shaft and of any
connected equipment. To guard against personal injury or damage to
equipment, verify that all guards are properly installed to help protect
against contact with rotating parts.
