Process and Application Parameters [300]
Section 11-3
Stop/Sleep when less than Minimum Speed [342]
With this function it is possible to put the VSD in “sleep mode” when it is run-
ning at minimum speed for the length of time set in menu “Stp<MinSpd [342]”.
The VSD will go into sleep mode after programmed time.
When the reference signal or PID Process controller output value (if PID Pro-
cess controller is used) raises the required speed value above the min speed
value, the VSD will automatically wake up and ramp up to the required speed.

If you want to use this function when having “process reference” signal via an
analogue input, you need to make sure that the concerning analogue input is
set up correct, meaning that AnIn Advanced parameter “AnIn1 FcMin [5134]”
should be set from “Min” (=default) to “User defined” and “AnIn1 VaMin
[5135]” set to a value less than “Min Speed [341]” to make it possible that the
analogue input reference can go below the “Min Speed” level to activate the
“Sleep mode”. This applies when PID Process controller is not used.
Note
If [381] PID Process controller is used, then the PID sleep functionality [386]-
[389] is recommended instead of [342].
Note
Menu [386] has higher priority than menu [342].
Communication information
Maximum Speed [343]
Sets the maximum speed at 10 V/20 mA, unless a user- defined characteristic
of the analogue input is programmed. The synchronous speed (Sync-spd) is
