3. Use the p 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 p 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.
4.2 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:

To enter the PROGRAM mode to access the parameters, press the Mode button. This will activate the
PASSWORD prompt (if the password has not been disabled). The display will read “00” and the upper
right-hand decimal point will be blinking, as shown below:
