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 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.

13.0 PROGRAMMING THE SCF DRIVE
The drive may be programmed by one of three methods: using the three buttons and 3-digit
LED display on the front of the drive, programming the Electronic Programming Module (EPM)
using the optional EPM Programmer, and through a serial link using serial communications.
This section describes programming the drive using the buttons and display, which are shown
below:
