1.6 – MAIN SPEED POTENTIOMETER CONNECTION
All drives are supplied with a remote mountable (5 kΩ) Main Speed Potentiometer to control motor speed. See Figures 1 – 4 on page 4.
Also see Section 11.4 on page 15.
KBVF-13, 14, 21D, 22D, 23, 23D, 24, 24D, 26D:
Wire the Main Speed Potentiometer to Terminals P1 (low), P2 (wiper), and P3 (high).
The drive is factory set for forward speed operation. The jumper on CON2 is set to the "F" position. For reverse speed operation, set the
jumper on CON2 to the "R" position.
KBVF-27, 27E, 27EF, 29, 29 (1P), 29E, 29EF, 29EF (1P), 42, 42E, 42EF, 45, 45E, 45EF, 48, 48E, 48EF:
Wire the Main Speed Potentiometer
to TB1 Terminals COM (low), SIG (wiper), and +5V (high). For forward speed operation, wire a jumper between Terminals FWD and COM.
For reverse speed operation, wire a jumper between Terminals REV and COM.
1.7 – JUMPER SETTINGS
All jumpers have been factory set for most applications. Some applications may require setting of the jumpers to tailor the drive for a specific
requirement. See Section 14 on pages 18 and 19.
1.8 – 60 Hz AND 50 Hz MOTOR OPERATION
The drive is factory set for 60 Hz motor operation. Jumper J1 on KBVF-13, 14, 21D, 22D, 23, 23D, 24, 24D, 26D and Jumper J5 on KBVF-27,
27E, 27EF, 29, 29 (1P), 29E, 29EF, 29EF (1P), 42, 42E, 42EF, 45, 45E, 45EF, 48, 48E, 48EF are set to the "60Hz" position. Jumper J2 on
KBVF-13, 14, 21D, 22D, 23, 23D, 24, 24D, 26D and Jumper J5 on KBVF-27, 27E, 27EF, 29, 29 (1P), 29E, 29EF, 29EF (1P), 42, 42E, 42EF,
45, 45E, 45EF, 48, 48E, 48EF are set to the "1X" position. For 50 Hz, 100 Hz, and 120 Hz motor operation, see Section 14.2 on page 18.
1.9 – TRIMPOT ADJUSTMENTS
All trimpots have been factory set for most applications. Some applications may require adjustment of the trimpots to tailor the drive for a
specific requirement. See Section 16 on page 20.
1.10 – SIGNAL FOLLOWING CONNECTION
An analog signal input can be used to control motor speed in lieu of the Main Speed Potentiometer. The drive output will linearly follow the
signal input. See Section 11.5 on page 15.
KBVF-13, 14, 21D, 22D, 23, 23D, 24, 24D, 26D:
Accepts a 0 – 5 Volt DC signal input. The signal input must be isolated from the AC Line.
Wire the signal input positive lead (+) to Terminal P2 and the negative lead (–) to Terminal P1.
WARNING!
Earth grounding signal wiring will damage the drive and void the warranty.
If a non-isolated signal is used, install the optional SIVFR-PS, which accepts voltage (0 to ±2.5 thru 0 to ±25 Volts DC) or current
(4 – 20 mA DC) signal inputs.
KBVF-27, 27E, 27EF, 29, 29 (1P), 29E, 29EF, 29EF (1P), 42, 42E, 42EF, 45, 45E, 45EF, 48, 48E, 48EF:
Built-in signal isolation. Accepts
voltage (0 to 5 Volts DC) or current (4 – 20 mA DC) signal inputs. Wire the signal input to Terminal Block TB1.
1.11 – DIAGNOSTIC LEDs
After applying power, observe the PWR (Power On) and ST (Status) LEDs to verify proper drive operation. See Section 17 on page 21.

SAFETY WARNING!
–
PLEASE READ CAREFULLY!
This product must be installed and serviced by a qualified technician, electrician, or electrical maintenance person familiar with its operation
and the hazards involved. Proper installation, which includes electrical connections, fusing or other current protection, and grounding, can
reduce the chance of electrical shocks, and/or fires, in this product or products used with this product, such as electric motors, switches,
coils, solenoids, and/or relays. Do not use this drive in an explosion-proof application. Eye protection must be worn and insulated adjustment
tools must be used when working with drive under power. This product is constructed of materials (plastics, metals, carbon, silicon, etc.)
which may be a potential hazard. Proper shielding, grounding, and filtering of this product can reduce the emission of radio frequency
interference (RFI) which may adversely affect sensitive electronic equipment. It is the responsibility of the equipment manufacturer and
individual installer to supply this Safety Warning to the ultimate end user of this product. (SW 8/2012)
The drive contains electronic start/stop circuits, which can be used to start and stop the drive. However, these circuits are never to be used
as safety disconnects since they are not fail-safe. Disconnect the input power for this purpose. Be sure to read and follow all instructions
carefully. Fire and/or electrocution can result due to improper use of this product.
This product complies with all CE directives pertinent at the time of manufacture. Contact Technical support for Declaration of
Conformity. Installation of a CE approved RFI filter is required. Additional shielded cable and/or AC Line cables may be required along with a
signal isolator.
