RECONDITIONIONG THE BUS CAPACITORS
If this drive has been in storage for over one year it is necessary to recondition the power supply bus capacitors. To recondition the bus
capacitors, apply the AC Line, with the drive in the Stop Mode, for a minimum of one hour. Not following this procedure will cause the bus
capacitors to fail.

SELECTABLE JUMPERS
The drive has customer selectable jumpers which must be set before it can be used.
WARNING!
HIGH VOLTAGE
! Disconnect the AC Line before changing position
of jumpers.
14.1 – AC LINE INPUT VOLTAGE SELECTION (KBVF-21D, 22D, 23D, 24D, 26D)
CAUTION!
The rated AC Line voltage of the drive must match the actual AC
Line input voltage. The drive setting must match the actual AC Line input voltage.
KBVF-21D, 22D, 23D, 24D:
For 208/230 Volt AC Line input (factory
setting), do not install the supplied jumper. For 115 Volt AC Line input,
install the supplied jumper onto Terminals J1A and J1B. See Figure 28.
KBVF-26D:
For 208/230 Volt AC Line input, install the supplied jumper
onto the center terminal and Terminal 230VAC (factory setting). For 115
Volt AC Line input, install the supplied jumper onto the center terminal and
Terminal 115VAC. Do not remove the center terminal. See Figure 29.
14.2 – MOTOR FREQUENCY SELECTION
The drive must be set for the actual motor nameplate frequency rating.
14.2.1 – SETTING THE DRIVE FOR 60 Hz and 50 Hz MOTOR OPERATION
The drive is factory set to operate 60 Hz motors.
KBVF-13, 14, 21D, 22D, 23, 23D, 24, 24D, 26D:
Jumper J1 is factory set to the
"60Hz" position and Jumper J2 is factory set to the "X1" position for 60 Hz motors.
For 50 Hz motors, set Jumper J1 to the "50Hz" position and set Jumper J2 to the
"X1" position. See Figure 30.
KBVF-27, 27E, 27EF, 29, 29 (1P), 29E, 29EF, 29EF (1P), 42, 42E, 42EF, 45,
45E, 45EF, 48, 48E, 48EF:
Jumper J5 is factory set to the "60Hz" and "1X"
positions for 60 Hz motors. For 50 Hz motors, set Jumper J5 to the "50Hz" and
"1X" positions. See Figure 31.
14.2.2 – SETTING THE DRIVE FOR TWO TIMES THE RATED MOTOR RPM
The drive can also operate the motor up to two times the rated RPM. However,
constant horsepower will result when operating the drive above the motor rated
frequency.
KBVF-13, 14, 21D, 22D, 23, 23D, 24, 24D, 26D:
For 120 Hz output with a 60 Hz
motor, set Jumper J1 to the "60Hz" position and set Jumper J2 to the "X2"
position. For 100 Hz output with a 50 Hz motor, set Jumper J1 to the "X2" position
and set Jumper J2 to the "50Hz" position. See Figure 30 and 32.
KBVF-27, 27E, 27EF, 29, 29 (1P), 29E, 29EF, 29EF (1P), 42, 42E, 42EF, 45,
45E, 45EF, 48, 48E, 48EF:
For 120 Hz output with a 60 Hz motor, set Jumper J5
to the "60Hz" and "2X" positions. For 100 Hz output with a 50 Hz motor, set
Jumper J5 to the "50Hz" and "2X" positions. See Figures 31 and 32.
14.3 – AUTOMATIC OR MANUAL START SELECTION
For Automatic Start (factory setting), the jumper is installed on Connector A/M.
The drive will automatically start when power is applied and a run command is given.
The drive will also automatically restart after a recovered fault due to undervoltage,
overvoltage, or short circuit. See Figure 33.
For Manual Start, see Section 11.6 on page 16.
