Type: Quick Start Commissioning Manual

Johnson Controls VFD66 Series is a variable frequency drive (VFD) that can be used to control the speed of condenser fans. It is designed for use in commercial and industrial applications, and it can help to improve the efficiency and performance of your HVAC system.

The VFD66 Series VFD has a number of features that make it a good choice for controlling condenser fans, including:

Variable speed control: The VFD66 Series VFD can be used to control the speed of condenser fans from 0 to 100%. This allows you to optimize the fan's performance for different operating conditions.
Energy efficiency: The VFD66 Series VFD can help to improve the energy efficiency of your HVAC system by reducing the fan's speed when it is not needed. This can help to save energy and reduce your operating costs.

Manual Operation

Operating the VFD66 Control from the Keypad

VFD66xxx-1 Setup

 The speed is controlled with P1 (P2 is not used).

 J2 = On, J3 = On, and J7 = On or Off.

VFD66xxx-2 Setup

 Set parameter 05 to PAd (manual input mode).

 Press the green button on the keyboard to run;

press the red button to stop.

 Use the up arrow key to increase the speed; use

the down arrow key to decrease the speed.

Note: If you cycle the power, the VFD66xxx-2 stops

and you must press the green button again.

Operating the VFD66 Control with a P35 Pressure Transducer or Any 0 to 5 VDC Signal

VFD66xxx-1 Setup

 J2 = On, J3 = Off, and J7 = On.

 P1 = minimum speed.

 P2 = minimum speed maintain (stop or hold).

VFD66xxx-2 Setup

 Set parameter 05 to Std (standard input mode;

factory default setting).

 Set parameter 65 to 5V (factory default setting).

 Set parameter 67 for the desired minimum speed

(factory default setting is 0 Hz).

 Set parameter 64 for either stop (factory default

setting; motor stops below the minimum speed

setting) or HOLd (motor idles), to obtain the

desired action at the minimum speed point.

Operating the VFD66 Control with a C450 Control Module or Any 0 to 10 VDC Signal

VFD66xxx-1 Setup

 J2 = On, J3 = Off, and J7 = Off.

VFD66xxx-2 Setup

 Set parameter 05 to Std (factory default setting).

 Set parameter 65 to 10V.

 Set parameter 67 for the desired minimum speed

(factory default setting is 0 Hz).

 Set parameter 64 for either stop (factory default

setting) or HOLd, to obtain the desired action at

the minimum speed point.

Operating the VFD66 Control with a Ratiometric P499 Series Electronic Pressure Transducer

VFD66xxx-1 Setup

 J2 = Off, J3 = On or Off, and J7 = On or Off.

 P1 = setpoint.

 P2 = proportional band.

VFD66xxx-2 Setup

 Set parameter 05 to EPt (electronic pressure

transducer input mode).

 Set parameter 65 to 5V (factory default setting) for

ratiometric sensors; set parameter 65 to 10V for

0 to 10 VDC sensors.

 Set parameter 61 for the desired setpoint. This

setting is calculated using the following equation:

)

Max. Pressure Rating of Sensor

(

10 + 80 x

Desired Pressure Setpoint

Example: If a 0 to 500 psig sensor is used and the

desired setpoint is 275 psig, then the setting for

parameter 61 is 10 + (80 x 275/500) or 54.

 Set parameter 62 for the desired proportional band

of the control. This setting is calculated using the

following equation:

]

Max. Pressure Rating of Sensor

[

80 x

(Pressure Setpoint – Min. Req. Pressure)

Example: If a 0 to 750 psig sensor with a setpoint

of 500 psig and a minimum required pressure of

410 psig is used, then the setting for parameter 62

is 80 x [(500 – 410)/750] or 9.6.

Changing Acceleration and Deceleration Parameters on the VFD66 Control

VFD66xxx-1 Setup

 If J4 = On, then the acceleration and deceleration

rate is 5 seconds (this value is in seconds/60Hz).

 If J4 = Off, then the acceleration and deceleration

rate is 30 seconds (this value is in

seconds/60 Hz).

VFD66xxx-2 Setup

 Set parameter 03 for acceleration

(in seconds/100 Hz). This setting is calculated

using the following equation:

Desired Acceleration Rate x 100

Example: A setting of 8.3 (in seconds/100 Hz)

equals a 5 second acceleration rate from

0 to 60 Hz.

 Set parameter 04 for deceleration

(in seconds/100 Hz). This setting is calculated

using the following equation:

Desired Deceleration Rate x 100

Example: A setting of 50 (in seconds/100 Hz)

equals a 30 second deceleration rate from

0 to 60 Hz.

Note: The settings for the acceleration and

deceleration parameters are adjustable from

0 to 3,200 seconds (this range is in seconds/100 Hz).

Selecting Single or Dual Sensors (High Signal Select) on the VFD66 Control

VFD66xxx-1 Setup

 If J8 = On, then dual sensors are configured with

high signal select.

 If J8 = Off, then single sensor is configured.

VFD66xxx-2 Setup

 Set parameter 63 to 1InP (factory default setting)

for single sensor configuration.

 Set parameter 63 to 2InP for dual sensor

configuration with high signal select.

Setting the Motor Rated Frequency on the VFD66 Control

VFD66xxx-1 Setup

 If J9 = On, then the motor rated frequency is

50 Hz.

 If J9 = Off, then the motor rated frequency is

60 Hz.

VFD66xxx-2 Setup

 Set parameter 39 to the motor rated frequency

(factory default setting is 60 Hz).
