After applying the power, the drive mode display should appear and no fault or alarm should be displayed. In the event of
a drive fault or error code, refer to
Drive Alarms, Faults, and Errors on page 236.
♦ Control Mode Selection
Select one o f the four motor control modes after applying power to the drive. Note that Closed Loop Vector modes
require PG encoder feedback cards. The table below indicates possible control modes depending on the motor type and
shows the required encoder feedback card.

• Motor Rotation Direction Setup
Check the direction o f motor rotation to verify the Up command causes the elevator to move in the upward direction.
Perform the following checks to confirm proper motor and load direction:
• The drive outputs motor voltage in U/T1-V/T2-W/T3 phase sequence when an Up command is issued. Check the
motor rotation with this phase sequence (for most motors clockwise is seen from the shaft side).
• If the motor drives the elevator in up direction with a U/T1-V/T2-W/T3 sequence, make sure parameter b1-14 is set to
0
.
• If the motor drives the elevator in down direction with a U/T1-V/T2-W/T3 sequence, make sure parameter b1-14 is set
to 1. Motor direction may also be changed by reversing two motor leads connected to U/T1, V/T2, W/T3 on the drive
terminal block.
