9. Apply power to the drive.
10. Repeat steps 4 and 5 above and verify that the motor rotation is
correct.
11. Complete the appropriate procedure based on the type of feedback
device used for the application:
❏ For Armature Voltage feedback - Continue with Step 10
Configure the Speed Feedback Parameters: on page 2-14
.
❏ For Analog Tachometer feedback - Assert a Jog command and
verify that the sign and value of Par 1408 [Tachometer Speed]
corresponds with the actual direction of the motor. If the sign
and value of Par 1408 [Tachometer Speed] and the motor
direction do not correspond, remove power from the drive and
reverse the tachometer connections at the drive. Continue with
Step 10 Configure the Speed Feedback Parameters: on
page 2-14.
❏ For Encoder feedback - Assert a Jog command and verify that
the sign and value of Par 420 [Encoder Speed] correspond with
the actual direction of the motor. If the sign and value of [Par
420 [Encoder Speed] and the motor direction do not
correspond, remove power from the drive and reverse the
encoder connections at the drive. Reverse the polarity of only
one channel, e.g., B and B NOT. Refer to Table 1.U on
page 1-40 for digital encoder terminal block designations.
