300
Function:
This parameter allows a choice between the
different functions available for the input, terminal 60.
Scaling of the input signal is effected in parameter
315 Terminal 60, min. scaling and parameter
316 Terminal 60, max. scaling .
Description of choice:
No function [0]. Is selected if the variable frequency
drive is not to react to signals connected to the terminal.
Reference [1]. If this function is selected, the reference
can be changed by means of an analog reference
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.
315 Terminal 60 Min. scaling
(AI 60 SCALE LOW)
Value:
0.0 - 20.0 mA
✭
0.0 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 Function
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,
parameter 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
function 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 expiration 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 variable frequency
drive 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]
