If one current feedback signal is connected, select
Feedback [2] on terminal 60.
315 Terminal 60 Min. scaling
315
(AI 60 SCALE LOW)
Value:
0.0 - 20.0 mA
Function:
In this parameter you can set the signal value that
will correspond to the minimum reference or mini-
mum feedback, parameter 204 Minimum reference,
Ref / 414 Minimum feedback, FB
MIN
Description of choice:
Set the required current value. If the Time out func-
tion is to be used (parameter 317 Time out and 318
Function after time out) the value set must be higher
than 2 mA.
316 Terminal 60 Max. scaling
316
(AI 60 SCALE HIGH)
Value:
0.0 - 20.0 mA
Function:
This parameter is used for setting the signal value
that is to correspond to the maximum reference
value, parameter 205 Maximum reference value,
Ref .
MAX
Description of choice:
Set the required current value.
317 Time out
317
(LIVE ZERO TIME O)
Value:
1 - 99 sec.
Function:
If the signal value of the reference or feedback sig-
nal connected to one of the input terminals 53 or 60
falls below 50 % of the minimum scaling for a period
longer than the time set, the function selected in pa-
rameter 318 Function after time out will be activated.
This function is only active if in parameter 309 Termi-
nal 53, min. scaling a value higher than 1 Volt has
been selected, or if in parameter 315 Terminal 60,
min. scaling a value higher than 2 mA has been se-
lected.

Stop and trip (STOP AND TRIP)
Function:
This parameter allows a choice of the function to be
activated after the expiry of the Time out (parameter
317 Time out). If a time-out function occurs at the
same time as a bus time-out function (parameter
513 Bus time interval function), the time-out function
in parameter 318 will be activated.
Description of choice:
The output frequency of the frequency converter can
20.0 mA
be:
- frozen at the present frequency [1]
- overruled to stop [2]
- overruled to jog frequency [3]
- overruled to max. output frequency [4]
- overruled to stop with subsequent trip [5]
