SETTING SELECTABLE JUMPERS
The drive has customer selectable jumpers which must be set before the drive can be used. For the location of jumpers, see
Figure 4, on
page XX
.
6.1
AC Line Input Voltage Selection (Jumper J1 (Models KBVF-21D, 22D, 23D, 24D, 26D* Only)): Jumper J1 is factory set to the
"230V" position for 208/230 Volt AC line input. For 115 Volt AC line input, set Jumper J1 to the "115V" position. Jumper J1 is
located on the upper PC board. See
Figures 7 and 8, on page XX
.
For 115 Volt AC line input, on Model KBVF-26D, the jumper must be removed and installed onto the "115VAC" position. Using
pliers, gently rock the female terminal back and forth vertically while pulling it upward. See
Figure 9, on page XX
.
* Note: On Model KBVF-26D, Jumper J1 is labeled "115VAC" and "230VAC".

60Hz and 50 Hz Motor Operation and Drive Output Frequency Selection (Jumpers J1 and J2): Both jumpers must be set for
the appropriate motor nameplate frequency rating. Jumpers J1 and J2 are located on the lower PC board.
6.2.1
Setting the Drive for 60 Hz or 50 Hz Motor Operation: The drive is factory set to operate 60 Hz motors. Jumper J1 is
factory set to the "60Hz" position and Jumper J2 is factory set to the "X1" position. For 50 Hz motors, set Jumper J1 to the
"50Hz" position, and be sure Jumper J2 is set to the "X1" position. Jumpers J1 and J2 are located on the lower PC board.
See

Setting the Drive for Two Times the Rated Motor RPM: The drive can also be used to operate the motor up to two times
the rated RPM. However, constant horsepower will result when operating the drive in the "X2" mode. See
Figure 11, on
page XX
.
For 120 Hz output with 60 Hz motor, be sure Jumper J1 is set to the "60Hz" position and set Jumper J2 to the "X2" position.
For 100 Hz output with 50 Hz motor, set Jumper J1 to the "50Hz" position and set Jumper J2 to the "X2" position. See
Figure 12, on page XX
.
