Follow the procedure below to check the motor rotation. This procedure assumes that the
drive has been powered up for the fi rst time, and that none of the parameters have been
changed.
1. Use the M button to decrease the speed setpoint to 00.0 Hz. The left decimal point will
illuminate as the speed setpoint is decreased. If the M button is held down, the speed
setpoint will decrease by tenths of Hz until the next whole Hz is reached, and then it will
decrease by one Hz increments. Otherwise, each push of the M button will decrease the
speed setpoint by a tenth of a Hz.
Once 00.0 Hz is reached, the display will toggle between “00.0” and “- - -”, which indicates
that the drive is in a STOP condition with a speed setpoint of 00.0 Hz.
2. Give the drive a START command. This can be done using one of several wiring methods
described in Section 11.0 - SCL/SCM CONTROL WIRING DIAGRAMS. Once the START
command is issued, the display will read “00.0”, indicating that the drive is in a RUN
condition with a speed setpoint of 00.0 Hz.
3. Use the L 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 L 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.
