P12.5 and P12.6 Feedback Minimum and Maximum
Minimum and maximum feedback values, corresponding to minimum and maximum of
the signal.
P12.7 PID Controller P Gain
Proportional gain. If set to 100%, a variation of 10% on error causes a variation of
10% on regulator output.
P12.8 PID Controller I-Time
Integral time constant. If set to 1s, a variation of 10% on error will cause a variation of
10% on regulator output after 1s.
P12.9 PID Controller D-Time
Derivative time. If set to 1s, a variation of 10% in 1s on error causes a variation of 10%
on regulator output.
P12.10 Error Value Inversion
0: Direct control. Frequency increases if set point > feedback
1: Inverted control. Frequency increases if set point < feedback
P12.11 PID Error Limit
If lower than 100%, determines a limit on max error. Useful to avoid excessive reac-
tion at motor startup.
P12.12 Sleep Frequency
This function will put the drive into sleep mode if the set point is reached and the out-
put frequency stays below the sleep limit for a longer time than set in the sleep delay
(P12.13). This means that the start command remains on, but the run request is
turned off. When the PID error value goes below, or above, the wake-up level depend-
ing on the set acting mode (P12.10) the drive will activate the run request again if the
start command is still on.
P12.13 Sleep Time Delay
Time of working at minimum frequency, before entering sleep condition.
P12.14 Wake Up Limit
The drive exits from sleep if the error exceeds this value. Direction of regulation
(P12.10) is internally considered.
P12.15 to P12.18
These parameters manage a more complex sleep sequence. After the time in P12.13,
the set point is increased of the term in P12.15, for the time in P12.16. This will cause
a higher output frequency. Frequency reference is then forced at minimum frequency
and the feedback value is sampled.
If the variation on actual value stays then lower than P12.17 for the time in P12.18, the
drive will enter sleep condition.
If this sequence is not needed, program P12.15=0%, P12.16=0s, P12.17=50%,
P12.18=1s.
