allocated to current and used as reference or feedback sources.
If the reference signal value associated with the selected current
input falls below 50% of the value set in par. 6-10, par. 6-12,
par. 6-20 or par. 6-22 for a time period longer than the time set
in par. 6-00, the function selected in par. 6-01 will be activated.
6-01 Live Zero Timeout Function
Option:
Function:
Select the time-out function. The function set in par. 6-01 will
be activated if the input signal on terminal 53 or 54 is below
50% of the value in par. 6-10, par. 6-12, par. 6-20 or par. 6-22
for a time period defined in par. 6-00. If several time-outs occur
simultaneously, the frequency converter prioritises the time-out
functions as follows:
1.
Par. 6-01
Live Zero Time-out Function
2.
Par. 8-04
Control-word Time-out Function
The output frequency of the frequency converter can be:
•
[1] frozen at the present value
•
[2] overruled to stop
•
[3] overruled to jog speed
•
[4] overruled to max. speed
•
[5] overruled to stop with subsequent trip
If you select set-up 1-4, par. 0-10,
Active Set-up
, must be set
to
Multi Set-up
, [9].
This parameter cannot be adjusted while the motor is running.
