FFunctional Description
127
PID sleep functionality
This function is controlled via a wait delay and a separate
wake-up margin condition. With this function it is possible
to put the AC drive in “sleep mode” when the process value
is at it’s set point and the motor is running at minimum
speed for the length of the time set in [386]. By going into
sleep mode, the by the application consumed energy is
reduced to a minimum. When the process feedback value
goes below the set margin on the process reference as set in
[387], the AC drive will wake up automatically and normal
PID operation continues, see examples.
PID sleep when less than minimum
speed [386]
If the PID output is equal to or less than minimum speed
for given delay time, the AC drive will go to sleep.
Communication information
PID Activation Margin [387]
The PID activation (wake-up) margin is related to the
process reference and sets the limit when the AC drive
should wake-up/start again.
Communication information
Example 1 PID control = normal (flow or
pressure control)
[321] = F (AnIn)
[322] = Bar
[310] = 20 Bar
[342] = 2 s (inactive since [386] is activated and have higher
priority)
[381]= On
[386] = 10 s
[387] = 1 Bar
The AC drive will stop/sleep when the speed (PID output) is
below or equal to Min Speed for 10 seconds. The AC drive
will activate/wake up when the “Process value” goes below
the PID Activation Margin which is related to the process
reference, i.e. goes below (20-1) Bar. See Fig. 96.

NOTE: When the drive is in Sleep mode, this is indicated
with “slp” in the lower left corner of the display.
