If the drive powers up correctly, follow the procedure given below to check the
motor rotation:
1. Use the q key to decrease the speed set point to the minimum value allowed
(0.50 Hz if Parameter 10 - MIN FRQ has not been changed).
2. Press the START key. The drive should indicate RUN, but if the speed set
point is .50 Hz, the motor may not rotate. Press the p key to increase the
speed set point until the motor starts to rotate.
3. If the motor is rotating in the wrong direction, press the STOP key and
remove power from the drive. Wait three minutes for the bus capacitors to
discharge, and swap any two of the motor wires connected to T1, T2, and
T3.
NOTE
The drive is phase insensitive with respect to incoming line voltage. Therefore,
to change the motor rotation, the phases must be swapped at the drive output
terminals or at the motor.
13 KEYPAD CONTROL
The drive can be operated in a number of different ways: keypad (LOCAL), control
devices wired to the terminal strip (REMOTE), serial communications (SERIAL), or
a combination of each. The drive should first be operated from the keypad during
initial start-up. Refer to Sections 14 - CONTROL WIRING, and 18 - DESCRIPTION
OF PARAMETERS for information on remote operation.
