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.
2VFD66 Series Condenser Fan Speed Controls Quick Start Commissioning Guide
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 ofSensor
(
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:
60
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:
60
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).
