4013 PID SLEEP DELAY
Time delay for the sleep function, see Figure 16. If the ACS 140 output
frequency is below a set level (parameter 4014
SLEEP LEVEL
) longer than
PID
SLEEP DELAY
, ACS 140 is stopped.
4014 PID SLEEP LEVEL
Level for activation of sleep function, see Figure 16. When the ACS 140 output
frequency falls below the sleep level, the sleep delay counter is started. When
the ACS 140 output frequency rises above the sleep level, the sleep delay
counter is reset.
Note! Sleep level comparison is also inverted when error value is inverted using
parameter 4005
ERROR VALUE INV
.
4015 WAKE-UP LEVEL
Level for deactivation of sleep function. This parameter sets a process actual
value limit for the sleep function (see Figure 16). When the actual value falls
below the limit, the sleep function is interrupted.
