315 Terminal 60, Minimum Scaling
(AI 60 SCALE LOW)
Value:
0.0 to 20.0 mA
Function:
This parameter determines the signal value that corresponds to the
minimum reference or the minimum feedback, parameter 204 Minimum
Reference, parameter 413, Minimum Feedback. See Reference
Handling or Feedback Handling.
Description of choice:
Set the required current value.
If the time-out function is to be used, parameter 317, Time Out, and
parameter 318, Function After Time Out, the value must be set to
> 2 mA.
316 Terminal 60, Maximum Scaling
(AI 60 SCALE HIGH)
Value:
0.0 to 20.0 mA
Function:
This parameter determines the signal value that corresponds to the
maximum reference or maximum feedback, parameter 205, Maximum
Reference Value, or parameter 414, Maximum Feedback. See
Reference Handling or Feedback Handling.
Description of choice:
Set the desired current value.
✭ I
ndicates factory default setting. Numbers in brackets [ ] represent selection as displayed on the serial bus.
317 Time Out
(LIVE ZERO TIME)
Value:
★ 4.0 mA 1 to 99 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 for a longer period than the Live Zero 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, Minimum Scaling, that exceeds
1 V, or if, in parameter 315, Terminal 60, Minimum Scaling, a value
has been selected that exceeds 2 mA.
Description of choice:
Set the desired time.
318 Function After Time Out
★ 20.0 mA (LIVE ZERO FUNCT.)
Value:
★ Off (NO FUNCTION)
Freeze output frequency
(FREEZE OUTPUT FREQ.)
Stop (STOP)
Jog (JOG FREQUENCY)
Max. output frequency (MAX FREQUENCY)
Stop and trip (STOP AND TRIP)
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 510, Bus Time Interval Function, the time-out function in
parameter 318 will be activated.
Description of choice:
The output frequency of the drive can:
- go to minimum (NO FUNCTION)
- be frozen at the present value (FREEZE OUTPUT
FREQUENCY)
- stop (STOP)
- run at the jog frequency set in parameter 209
(JOG FREQUENCY)
- run at the maximum frequency set in parameter 202
(MAX. FREQUENCY)
- stop and send an alarm (STOP AND TRIP)
★ 10 sec.
