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.

Control Connections

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).

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 (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.

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:

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:

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.
