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 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).
