PV200
Closed Loop Proportional Valve Controller
PV200 - The title parameter is fixed. It displays the model number and the firmware version.
PROPORTIONAL GAIN – Sets the P term in a PID control loop. It is a multiplication of the error added to the
output. The higher the setting, the faster the response will be. Also, higher settings result in shorter ramp time,
but it can cause oscillation. It is variable type.
INTEGRAL TIME – Sets the I term in a PID control loop. It is the sum of the error over time. It overcomes an offset
in the output or to correct for small deviations over time. A shorter time will result in more integral control but
can cause oscillation. A value of zero will disable the integral term. It is variable type.
DERIVATIVE GAIN – Sets the D term in a PID control loop. It is the rate of change of error. The higher the
derivative gain, the quicker the system will respond to sudden changes. It is variable type.
TARGET DEADBAND – Sets the error tolerance of the PID loop. The control will only respond to error greater than
the Target Deadband parameter. It is variable type.
INVERT TARGET – Sets the target position input inverted. This will result in the minimum signal corresponding to
the max target value and vise-versa. It is variable type.
TARGET MINIMUM- Sets the minimum target position input (0 to 100%). The value in the brackets is the present
command input.
TARGET MAXIMUM - Sets the maximum target position input (0 to 100%). The value in the brackets is the present
command input.
POSITION MINIMUM - Sets the minimum actual position input (0 to 100%). The value in the brackets is the present
command input.
POSITION MAXIMUM - Sets the maximum actual position input (0 to 100%). The value in the brackets is the
present command input.
A MINIMUM OUTPUT - Sets the minimum output current for coil A (Amps). The value in the brackets is the present
command input.
A MAXIMUM OUTPUT - Sets the maximum output current for coil A (Amps). The value in the brackets is the
present output current.
A OVERRIDE - Sets the output current for a digital forward override command. No ramping takes place during
override operations. The value in the brackets is the present output current.
B MINIMUM OUTPUT - Sets the minimum output current for coil B (Amps). The value in the brackets is the present
command input.
