signal. If reference signals are connected to more than
one input, these reference signals must be added up.
If one current feedback signal is connected, select
Feedback [2] on terminal 60.
Wobble [10]
The delta frequency can be controlled by the analog
input. If WOBB.DELTA FREQ is selected as analog in-
put (par. 308 or par. 314) the value selected in par. 702
equals 100 % analog input.
Example: Analog input = 4-20 mA, Delta freq. par. 702
= 5 Hz • 4 mA = 0 Hz and 20 mA = 5 Hz. If this function
is chosen, see Wobble Instruction MI28JXYY for fur-
ther information.
315 Terminal 60 Min. scaling
(AI 60 SCALE LOW)
Value:
0.0 - 20.0 mA
4.0 mA
Function:
In this parameter you can set the signal value that will
correspond to the minimum reference or minimum
feedback, parameter 204 Minimum reference,
Ref
MIN
/ 414 Minimum feedback, FB
MIN
.
Description of choice:
Set the required current value. If the Time out function
is to be used (parameter 317 Time out and 318 Func-
tion after time out ) the value set must be higher than
2 mA.
316 Terminal 60 Max. scaling
(AI 60 SCALE HIGH)
Value:
0.0 - 20.0 mA
20.0 mA
Function:
This parameter is used for setting the signal value that
is to correspond to the maximum reference value, pa-
rameter 205 Maximum reference value, Ref
MAX
.
Description of choice:
Set the required current value.
317 Time out
(LIVE ZERO TIME O)
Value:
1 - 99 sec.
10 sec.
Function:
If the signal value of the reference or feedback signal
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 parameter
318 Function after time out will be activated. This func-
tion is only active if in parameter 309 Terminal 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 selected.
Description of choice:
Set the required time.
318 Function after time out
(LIVE ZERO FUNCT.)
Value:
No operation (NO OPERATION) [0]
Freeze output frequency
(FREEZE OUTPUT FREQ.) [1]
Stop (stop) [2]
Jog (jog) [3]
Max. speed (MAX SPEED) [4]
Stop and trip (STOP AND TRIP) [5]
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 param-
eter 318 will be activated.
Description of choice:
The output frequency of the frequency converter can
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]
