For reasons of accuracy, voltage losses in long
signal lines can be compensated for.
314 Terminal 60, analog input current
(AI [MA] 60 FUNCT.)
Value:
See description of parameter 308.
✭
Reference
Function:
This parameter allows a choice between the
different functions available for the input, terminal
60. Scaling of the input signal is done in parameter
315 Terminal 60, min. scaling and in parameter
316 Terminal 60, max. scaling .
Description of choice:
See description of parameter 308 Terminal 53,
analogue input voltage .
315 Terminal 60, min. scaling
(AI 60 SCALE LOW)
Value:
0.0 - 20.0 mA
✭
4.0 mA
Function:
This parameter determines the signal value that
corresponds to the minimum reference or the minimum
feedback, parameter 204 Minimum reference,
Ref
MIN
/413 Minimum feedback, FB
MIN
. See Reference
handling or Feedback handling .
Description of choice:
Set the required current value.
The time-out function is to be used (parameters
317 Time out and 318 Function after time out ),
the value must be set to > 2 mA.
316 Terminal 60, max. scaling
(AI 60 SCALE HIGH)
Value:
0.0 - 20.0 mA
✭
20.0 mA
Function:
This parameter determines the signal value that
corresponds to the maximum reference value,
parameter 205 Maximum reference value, Ref
MAX
.
See Reference handling or Feedback handling .
Description of choice:
Set the desired current value.
317 Time out
(LIVE ZERO TIME)
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,
54 or 60 drops to below 50% of the minimum
scaling during a period longer than the preset time,
the function selected in parameter 318 Function
after time out will be activated.
This function will only be active if, in parameter 309
or 312, a value has been selected for terminals
53 and 54, min. scaling that exceeds 1 V, or if, in
parameter 315 Terminal 60, min. scaling , a value
has been selected that exceeds 2 mA.
Description of choice:
Set the desired time.
318 Function after time out
(LIVE ZERO FUNCT.)
Value:
✭
Off (NO FUNCTION)
[0]
Freeze output frequency (FREEZE OUTPUT FREQ.) [1]
Stop (STOP) [2]
Jog (JOG FREQUENCY) [3]
Max. output frequency (MAX FREQUENCY) [4]
Stop and trip (STOP AND TRIP)
[5]
Function:
This is where to select the function to be activated after
the end of the time-out period (parameter 317 Time out ).
If a time-out function occurs at the same time
as a bus time-out function (parameter 556 Bus
time interval function ), the time-out function in
parameter 318 will be activated.
