VFD68 Variable Frequency Drives Product Bulletin1 Refer to the QuickLIT website for the most up-to-date version of this document.The VFD68 Variable Frequency Drive providesthree-phase motor speed control in a variety of HVACR applications. The VFD68drive 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 P499Electronic 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 VFD68drive 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.Figure 1: VFD68 Variable Frequency DrivesTable 1: Features and BenefitsFeaturesBenefitsSelectable Input TypesAllow use with 0–5 VDC (ratiometric), 0–10 VDC, or 4–20 mA input signals from transducers, sensors, and controllers.High Input Signal Selection of Two Similar Inputs (230 or 460 volt models only)Provides fan speed control of dual circuit condensing units, based on the highest pressure circuit.Compact DesignProvides for easy and flexible installation.Three-Phase, 230, 460, or 575 VAC ModelsCan control a wide variety of three-phase motors ranging up to 10 hp.Simple and Advanced End-User SettingsProvide quick and simple application setup and operation, as well as advanced setup parameters for custom applications.VFD68 Variable Frequency DrivesProduct BulletinCode No. LIT-12012068Issued October 2017VFD68 Variable Frequency Drives Product Bulletin2ApplicationThe 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 costThe 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 temperaturesOperationDepending on the model, the VFD68 drive’s mode of operation is indicated by LEDs or icons on the drive’s operation panel (Figure2 or Figure3).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.VFD68 Variable Frequency Drives Product Bulletin3Operation Panel on 230 VAC and 460 VAC ModelsThe RUN, MON, and PRM LEDs provide drive status and indicate the type of information being displayed on the operation panel (Figure2).RUN LED: The LED state (onsteady, flashing, or flickering) provides information regarding the drive and motor run status.MON LED: Indicates that the monitor is displaying the drive’s run status.

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 InformationUse Figure4 and Table4 to select the desired model of VFD68 Drive. For example, a VFD68BGG would be rated for 230 VAC ±10% and 2horsepower. See Table5 through Table7 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.Figure 4: VFD68 Drive Model VFD68-2CVoltageKilowatts(Horsepower)Dimensions H x W x DFIG:VFD68_slctnTable 4: VFD68 Drive Model InformationVoltagekW (Horsepower)Dimensions, H x W x D, mm (in.)B200–240 VAC, 50/60 Hz0.1 (1/8)128 x 68 x 81 (5 x 2-11/16 x 3-3/16)C400–480 VAC, 50/60 Hz0.2 (1/4)128 x 68 x 113 (5 x 2-11/16 x 4-7/16)D575 VAC, 50 Hz0.4 (1/2)128 x 68 x 133 (5 x 2-11/16 x 5-1/4)F0.75 (1)128 x 108 x 130 (5 x 4-1/4 x 5-1/8)G1.5 (2)128 x 108 x 136 (5 x 4-1/4 x 5-5/16)H2.2 (3)128 x 108 x 156 (5 x 4-1/4 x 6-1/8)J3.7 (5)128 x 108 x 166 (5 x 4-1/4 x 6-1/2)K5.5 (7-1/2)128 x 170 x 142 (5 x 6-11/16 x 5-5/8)L7.5 (10)150 x 220 x 155 (5-15/16 x 8-11/16 x 6-1/8)M11 (15)150 x 140 x 136 (5-15/16 x 5-1/2 x 5-5/16)N15 (20)150 x 220 x 148 (5-15/16 x 8-11/16 x 5-13/16)P260 x 220 x 190 (10-1/4 x 8-11/16 x 7-1/2)IMPORTANT:Frequently starting and stopping the VFD shortens the lifespan of the VFD68drive.
