For 120 Hz output with 60 Hz motor, set Jumper J4 to the “2X” position and
be sure Jumper J5 is set to the “60Hz” position. For 100 Hz output with 50
Hz motor, set Jumper J4 to the “2X” position and set Jumper J5 to the “50Hz”
position. See Figure 14.

7 TRIMPOT ADJUSTMENTS
The drive contains trimpots that are factory set for most applications. See Figure 3, on page
12, for the location of the trimpots and their approximate factory calibrated positions. Some
applications may require readjustment of the trimpots in order to set the drive for a specific
requirement. The trimpots may be readjusted as described.
WARNING! IF POSSIBLE, DO NOT ADJUST TRIMPOTS WITH THE MAIN
POWER APPLIED. IF ADJUSTMENTS ARE MADE WITH THE MAIN POWER APPLIED, AN
INSULATED ADJUSTMENT TOOL MUST BE USED AND SAFETY GLASSES MUST BE
WORN. HIGH VOLTAGE EXISTS IN THIS DRIVE. FIRE AND/OR ELECTROCUTION CAN
RESULT IF CAUTION IS NOT EXERCISED. “ALL” SAFETY WARNINGS ON, PAGE 8,
MUST BE READ AND UNDERSTOOD BEFORE
PROCEEDING.
7.1 MINIMUM SPEED (MIN): Sets the minimum
speed of the motor. The MIN Trimpot is factory
set to 0% of frequency setting. For a higher
minimum speed, setting, rotate the MIN Trimpot
clockwise. See Figure 16.
