Functional Description
CG Drives & Automation, 01-5326-01r3b
11.3.5 Speed [340]
Menu with all parameters for settings regarding to speeds,
such as Min/Max speeds, Jog speeds, Skip speeds.
Minimum Speed [341]
Sets the minimum speed. The minimum speed will operate
as an absolute lower limit. Used to ensure the motor does
not run below a certain speed and to maintain a certain
performance.
Communication information
Stop/Sleep when less than Minimum
Speed [342]
With this function it is possible to put the AC drive in “sleep
mode” when it is running at minimum speed for the length
of time set in menu “Stp<MinSpd [342]”. The AC drive will
go into sleep mode after programmed time.
When the reference signal or PID Process controller output
value (if PID Process controller is used) raises the required
speed value above the min speed value, the AC drive will
automatically wake up and ramp up to the required speed.
Fig. 89
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
.
Communication information
Maximum Speed [343]
Sets the maximum speed. The maximum speed will operate
as an absolute maximum limit. This parameter is used to
prevent damage due to high speed.
The synchronous speed (Sync-spd) is determined by the
parameter motor speed [225].
Default:
0 rpm
Range:
0 - Max Speed
Dependent on: Set/View ref [310]
NOTE: A lower speed value than the set minimum speed
can be shown in the display due to motor slip.

NOTE: If [381] PID Process controller is used, then the

instead of [342]. See further page 127.
