Danfoss VLT 5000 Series Instruction Manual page 119

Function:
This parameter determines the value of the reference
signal that is to correspond to the minimum reference
value set in parameter 204.
If the timeout function of parameter 317 is used, the
value must be set at >2 mA.
Description of choice:
Set the desired current value.
See also section Handling of single references.
316 Terminal 60, max. scaling
(AI 60 SCALE HIGH)
Value:
0.0 - 20.0 mA
Function:
This parameter sets the value of the reference signal
that is to correspond to the maximum reference value
set in parameter 205.
Description of choice:
Set the desired current value.
See also section Handling of single references .
317 Time out
(LIVE ZERO TIME O)
Value:
0 - 99 sec.
Function:
If the signal value of the reference signal connected to
the input, terminal 60, falls below 50% of the value set
in parameter 315 for a period longer than the time set
in parameter 317, the function selected in parameter
318 will be activated.
Description of choice:
Set the desired time.

318 Function after time out
(LIVE ZERO FUNCT.)
Value:
Off (OFF)
Freeze output frequency (FREEZE OUTPUT
FREQ.)
Stop (STOP)
Jog (JOGGING)
Max. speed (MAX SPEED)
Stop and trip (STOP AND TRIP)
Function:
This parameter allows a choice of the function to be
activated if the input signal on terminal 60 drops below
2 mA, provided parameter 315 has been set higher
20.0 mA
than 2 mA and that the preset time for time-out (pa-
rameter 317) has been exceeded.
If more time-outs occur at the same time the adjustable
frequency drive will give the following priority to the
time-out function:
1.
Parameter 318 Function after time out
2. Parameter 346 Function after encoder loss
3. Parameter 514 Bus time interval function
Description of choice:
The output frequency of the adjustable frequency drive
can be:
frozen at the present value
-
10 sec.
- overruled to stop
- overruled to jog frequency
- overruled to max. frequency
- overruled to stop with subsequent trip.
