Follow the procedure below to check the motor rotation. This procedure assumes that the drive has
been powered up for the first time, and that none of the parameters have been changed.
1. Use the
t button to decrease the speed setpoint to 0 Hz. The left decimal point will illuminate as
the speed setpoint is decreased.
Once 0 Hz is reached, the display will toggle between “00” and “- -”, which indicates that the
drive is in a STOP condition with a speed setpoint of 0 Hz.
2. Give the drive a START command. This can be done using one of several wiring methods
described in Section 11.0 - SM-Basic CONTROL WIRING DIAGRAMS. Once the START
command is issued, the display will read “00”, indicating that the drive is in a RUN condition
with a speed setpoint of 0 Hz.
3. Use the
s button to increase the speed setpoint until the motor starts to rotate. The left decimal
point will light as the speed setpoint is increased.
4. If the motor is rotating in the wrong direction, give the drive a STOP command 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. This means that the
drive will operate with any phase sequence of the incoming three phase voltage. Therefore, to change
the motor rotation, the phases must be swapped at the drive output terminals or at the motor.
