Process and Application Parameters [300]
Section 11-3
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 VSD 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 VSD will wake up automatically and normal PID operation contin-
ues, see examples.
Note
When the VSD is in Sleep mode, this is indicated with “slp” in the lower left
corner of the display.
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 VSD will go to sleep.
Communication information
Note
Menu [386] has higher priority than menu [342].
PID Activation Margin [387]
The PID activation (wake-up) margin is related to the process reference and
sets the limit when the VSD should wake-up/start again.
Communication information
Note
The margin is always a positive value.
Example 1 PID control = normal (flow or pressure control)
[321] = F (AnIn)
[322] = Bar
[310] = 20 Bar
