If the value of the parameter is
set to 100% a change of 10% in
the error value causes the con-
troller output to change by 10%.
If this parameter is set to 1,00
second a change of 10% in the
error value causes the control-
ler output to change by 10.00%/
s.
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%.
0 = Normal (Feedback < Setpoint
-> Increase PID output)
1 = Inverted (Feedback < Set-
point -> Decrease PID output)
Drive goes to sleep mode when
the output frequency stays
below this limit for a time
greater than that defined by
parameter P12.13.
The minimum amount of time
the frequency has to remain
below the Sleep level before the
drive is stopped.
Defines the level for the PID
feedback value wake-up.
