VFD68 Variable Frequency Drives Product Bulletin 1
Refer to the QuickLIT website for the most up-to-date version of this document.
The VFD68 Variable Frequency Drive provides
three-phase motor speed control in a variety of HVACR
applications. The VFD68 drive is designed primarily for
condenser fan speed control on HVAC and
refrigeration condensing units, but can also be set up to
control a variety of pumps, blowers, and fans.
The VFD68 drive accepts input signals from
P499 Electronic Pressure Transducers, or other
devices that provide a 0–5 VDC, 0–10 VDC, or
4–20 mA signal.
The application-specific design of the VFD68 drive
provides a simple interface, which makes the drive
easy to understand and operate.
You can quickly and easily reconfigure the VFD68 drive
to control variable speed pumps in cooling and heating
applications, or to control variable speed supply fans in
VAV applications.
The VFD68 drive is an RS485, RTU-compliant
ModBus® slave device and can be integrated into a
ModBus network.

Application
The VFD68 drive accepts input signals from a variety of
pressure transducers, temperature sensors, and
low-voltage controllers to provide continuous response
to changing condenser load conditions.
The VFD68 drive allows the system to:
• maintain optimum condenser head pressure
• operate in low ambient temperature conditions
down to -40ºC (-40ºF)
• reduce short-cycling, which occurs when using
On/Off fan controls
• maintain a more stable evaporator temperature
• operate more efficiently, reducing electricity cost
The VFD68 drive can also:
• help optimize compressor operation, reduce wear,
and extend compressor life by stabilizing the
condenser head pressures
• reduce motor repair and replacement costs by
eliminating the condenser fan short-cycling
• extend refrigerated product life and provide more
consistent comfort cooling by stabilizing evaporator
temperatures
Operation
Depending on the model, the VFD68 drive’s mode of
operation is indicated by LEDs or icons on the drive’s
operation panel (Figure 2 or Figure 3).
PU Mode: The Parameter Units (PU) mode is manual
control mode. In PU mode, the drive and motor are
completely controlled using the buttons and setting dial
on the drive’s user interface. No external analog
signals or network signals control the drive operation.
The PU mode is typically used to set up, test, and
troubleshoot the drive and motor operation using
controlled input signal values.
EXT Mode: In the External (EXT) mode, the drive and
motor are responding to a signal or signals from one or
two analog input signal devices such as pressure
transducers or analog controllers. This is the typical
mode of operation for the drive when it is controlling a
condenser fan or other three-phase HVACR motor
application.
PU/EXT Mode: In PU/EXT mode, the drive responds to
the connected external signal devices, and you can
edit the drive setup values. The PU/EXT mode is
typically used to set up your drive for initial operation,
or to adjust setup parameters on an operating
application.
IMPORTANT: Use this VFD68 Variable
Frequency Drive only as an operating control.
Where failure or malfunction of the VFD68 Drive
could lead to personal injury or property damage
to the controlled equipment or other property,
additional precautions must be designed into the
control system. Incorporate and maintain other
devices, such as supervisory or alarm systems or
safety or limit controls, intended to warn of or
protect against failure or malfunction of the
VFD68 Drive.
IMPORTANT : Utiliser ce VFD68 Variable
Frequency Drive uniquement en tant que
dispositif de régulation. Lorsqu'une défaillance
ou un dysfonctionnement du VFD68 Drive risque
de provoquer des blessures ou d'endommager
l'équipement contrôlé ou un autre équipement,
la conception du système de contrôle doit
intégrer des dispositifs de protection
supplémentaires. Veiller dans ce cas à intégrer
de façon permanente d'autres dispositifs, tels
que des systèmes de supervision ou d'alarme,
ou des dispositifs de sécurité ou de limitation,
ayant une fonction d'avertissement ou de
protection en cas de défaillance ou de
dysfonctionnement du VFD68 Drive.

Selecting a Motor
Required Motor Specifications
Motors used with the VFD68 drive must:
• be AC induction three-phase motors that are UL
Recognized and CSA Certified, or equivalent
• be rated for:
• 230 VAC, 50/60 Hz
• 460 VAC, 50/60 Hz
• 575 VAC, 60 Hz
• have an Inverter Rating (460 VAC motors)
• have Insulation Class F or better
The VFD68 drive is intended for use with variable
speed motors that are rated for 40:1 operation.
Multiple Motors
A VFD68 drive can control multiple motors wired in
parallel; however, the sum of the Full Load Amperes
(FLA) ratings for the motors must not exceed the
maximum output current rating of the VFD68 drive,
including any de-rating due to altitude. Refer to the
VFD68 Variable Frequency Drive Technical Bulletin
(Part No. 24-7664-3051) for de-rating information.
If three-phase power is not available as supply power
for the VFD68 drive, refer to the VFD68 Variable
Frequency Drive Technical Bulletin
(Part No. 24-7664-3051).
Ordering Information
Use Figure 4 and Table 4 to select the desired model of
VFD68 Drive. For example, a VFD68BGG would be
rated for 230 VAC ±10% and 2 horsepower. See
Table 5 through Table 7 for available production
models.
.
IMPORTANT: When selecting the motor, do not
exceed the maximum output current rating of the
VFD68 drive.
IMPORTANT: Do not control both single-phase
and three-phase motors with the same VFD68 drive.

IMPORTANT: Frequently starting and stopping the VFD shortens the lifespan of the VFD68 drive. In
applications where the drive will start or stop frequently, select a VFD which has an output current rating that is
1.5 to 2 times greater than the FLA current rating of the three-phase motor.
