Parameter description
P12.11
PID
ERROR LIMIT
If lower than 100%, determines a limit on max error. Useful to avoid excessive reaction at mo-
tor startup.
P12.12
S
LEEP FREQUENCY
This function will put the drive into sleep mode if the setpoint is reached and the output fre-
quency stays below the sleep frequency for a longer time than that set with 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 depending on the set acting
mode (P12.10) the drive will activate the run request again if the start command is still on.
P12.13
S
LEEP TIME DELAY
Time of working at minimum frequency, before entering sleep condition.
P12.14
W
AKE UP LIMIT
The drive exits from sleep if the error exceeds this value. Direction of regulation (P12.10) is in-
ternally considered.
P12.15
S
LEEP SETPOINT BOOST
P12.16
S
LEEP BOOST TIME
P12.17
S
LEEP MAX LOSS
P12.18
S
LEEP LOSS CHECK TIME
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 an 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.
