How to Program
Function:
The integrator provides an increasing gain
at a constant error between the setpoint
and the feedback signal. The integ ral time
needed by the integrator to reach the same
gain as t h e proportional gain.
7-35 Process PID Differentia tion Time
Range:
0.00 - 1 0.00 s
*
0.00s
Function:
The differentiator does not react to a constant
error. It only provides a gain whe n the error
changes. The quicker the error changes, the
stronger the gain from the differentiator.
7-36 Process PID Differentia ti on Gain Limit
Range:
1.0 - 50.0 N/A
*
5.0N/A
Function:
Set a limit for the differentiator gain (DG). The
DG will increase if there are fast changes. Limit
the DG to obtain a pure differentiator gain
at slow chang es and a constant differentiator
gain where q uick changes occur.
7-38 Process PID Feed Forward Factor
Range:
0 - 500%
*
0%
Function:
The FF factor sends a large or small part of the
reference signal around the PID control. In this way,
the PID control only affects part of the control signal.
7-39 On Reference Bandwidth
Range:
0 - 200%
*
5%
Function:
When the PID Control E rror (the difference
between the reference and the feed back) is
less than the set value of this parameter, the
On Reference status bit is high (1).
