Function:
When the difference between the feedback and
the setpoint reference is less than the value of
this parameter, the frequency converter's display
shows "Run on Reference". This status can be
communicated externally by programming the
function of a digital output for [8] Run on
Reference/No Warning. In addition, for serial
communications, the On Reference status bit of
the frequency converter's Status Word is high (1).
The On Reference Bandwidth is calculated as a
percentage of the setpoint reference.
Function:
Quick control is obtained at high amplification.
However if amplification is too great, the
process may become unstable.
Function:
Enter the process controller integral time.
Obtain quick control through a short integral
time, though if the integral time is too short,
the process becomes unstable. An excessively
long integral time disables the integral action.
Function:
