CL Setting range Description
[Default]
2 [PID analog] The voltage is controlled using an analog PID controller.
3pos controller The voltage is controlled using a three-step controller.
Off Voltage control is not carried out.
2 0.01 to 100.00 The proportional coefficient specifies the gain. By increasing the gain, the
response is increased to permit larger corrections to the variable to be con‐
[1.00]
trolled. The farther out of tolerance the process is the larger the response
action is to return the process to the tolerance band. If the gain is configured
too high, the result is excessive overshoot/undershoot of the desired value.
Notes
This parameter is only visible if voltage control (parameter
configured to "PID analog".
2 0.01 to 100.00 The integral gain identifies the I part of the PID controller. The integral gain
corrects for any offset (between setpoint and process variable) automatically
[1.00]
over time by shifting the proportioning band. Reset automatically changes the
output requirements until the process variable and the setpoint are the same.
This parameter permits the user to adjust how quickly the reset attempts to
correct for any offset. The integral gain constant must be greater than the
derivative time constant. If the integral gain constant is too large, the engine
will continually oscillate. If the integral gain constant is too small, the engine
will take too long to settle at a steady state.
Notes
This parameter is only visible if voltage control (parameter
configured to "PID analog".
2 0.01 to 100.00 The derivative ratio identifies the D part of the PID controller. By increasing
this parameter, the stability of the system is increased.
[0.01]
The controller will attempt to slow down the action of the actuator in an
attempt to prevent excessive overshoot or undershoot.
Essentially this is the brake for the process. This portion of the PID loop oper‐
ates anywhere within the range of the process unlike reset.
Notes
This parameter is only visible if voltage control (parameter
configured to "PID analog".
The default configured controller acts like a PI controller what is the valid D
part setting for systems with secondary controllers.
