3. Use the button to increase the speed setpoint until the motor starts to rotate. The left
decimal point will light as the speed setpoint is increased. If the button is held down,
the speed setpoint will increase by tenths of Hz until the next whole Hz is reached,
and then it will increase by one Hz increments. Otherwise, each push of the button
will increase the speed setpoint by a tenth of a Hz.
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 U, V, W.
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.
