0: the regulator controls the output frequency; full scale value defined by P-01;
1=voltage [ 0 ] 1: controls the output voltage; full scale value defined by P-02;
0 = off 1 = on The sign of the error signal between reference and feedback is reversed (and the
[ 0 ] adjustment effect too).
0=direct 1=sum 1:the reg. output is added to the freq. reference value or to the voltage value provided
(feed/forw) [ 0 ] by the V/F characteristic; 0: the output act as set by b-43.
0 = off 1 = on Limits the regulator output in the positive direction; 0 allows the output to assume
[ 0 ] positive values too.
0 = off 1 = on Limits the regulator output in the negative direction; 0 allows the output to assume
[ 0 ] negative values too.
0 = off 1 = on Allows the integral term to match the limits set to the output by b-46 and b-47.
[ 0 ]
Allows the initialization by means of the run control. NOTE: this could cause a very

slow response of the regulator, even with high gains.

ESCRIPTION
The regulator enabling and the coefficients selection can be made through
terminal control board by configuring two out of the five control inputs as Ix-
PID and Ix-P12 input respectively:
Ix-PID = 1 the PID regulator is controlled from the terminal board.
Ix-P12 = 1 selects the coefficient set N. 1; 0 refers to set 2.
When enabling the regulator or changing the coefficients set, the integral
term is used according to the present output and coefficients, by taking into
account possible limits applied to the output and to the integral term; this
avoid sudden output changes ("bumpless" operation).
If the coefficient change occurs when the error is significant, the system
response speed is affected by the integral action weight, as the proportional
and derivative term weight is compensated by the integral term.
A max. tolerance interval can be defined for the error that, if exceeded,
actuates a signalling available on the terminal board by properly configuring
one of the digital output OUT1.
The error tolerance control is enabled when the error falls within the preset
interval for the first time (P91 and P92 ) such a condition can be displayed
via P46= 21,22, 23. During start-up transient (that is: not before the regulator
error falls within the tolerance limits at least once), it is possible to disable
the outputs through P-46 value 24, or 25, or 26. The possible sign reversal
made by setting b-44=1 has no importance for tolerance control.
The out-of-tolerance signalling available on the digital outputs can be
enabled when exceeding one of the two limits (Ox-ERP), or the positive (Ox-
EPP) or negative (Ox-EPN) limit only.
To facilitate the parameters setting, the following items can be displayed:
reference signal:
feedback signal:
error:
integral component:
output:
NOTE: The integral term is set to zero if the integral action time is set to
the max. value, i.e. 99.99. The derivative term is null if the derivative
action time is set to zero.
