131 I/O frequency reference selection, place B 3 (2.1.12)
See the values of the parameter ID117 above.
132 PID controller D-time 57 (2.1.14)
The parameter ID132 defines the derivation time of the PID controller. If this parameter
is set to 1,00 second a change of 10% in the error value during 1.00 s causes the
controller output to change by 10.00%. If the parameter value is set to 0.00 s the PID
controller will operate as PI controller.
See examples below.
Example 1:
In order to reduce the error value to zero, with the given values, the frequency drive
output behaves as follows:
Given values:
Par. 2.1.12, P = 0%
Par. 2.1.13, I-time = 1.00 s
Par. 2.1.14, D-time = 0.00 s
Min freq. = 0 Hz
Error value (setpoint – process value) = 10.00% Max freq. = 50 Hz
In this example, the PID controller operates practically as I-controller only.
According to the given value of parameter 2.1.13 (I-time), the PID output increases by 5
Hz (10% of the difference between the maximum and minimum frequency) every second
until the error value is 0.
