6-00 Live Zero Timeout Time
Range:
10 s* [1 - 99 s]
6-01 Live Zero Timeout Function
Option:
[0] * Off
[1] Freeze output
[2] Stop
[3] Jogging
[4] Max. speed
[5] Stop and trip
Function:
Enter the Live Zero Time-out time period. Live Zero Time-out Time is active for analog inputs, i.e.
terminal 53 or terminal 54, 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
Low Voltage , par. 6-12 Terminal 53 Low Current , par. 6-20 Terminal 54 Low Voltage or
Terminal 54 Low Current for a time period longer than the time set in par. 6-00 Live Zero
par. 6-22
Timeout Time , the function selected in par. 6-01 Live Zero Timeout Function will be activated.
Function:
Select the time-out function. The function set in par. 6-01
vated if the input signal on terminal 53 or 54 is below 50% of the value in par. 6-10
Low Voltage , par. 6-12 Terminal 53 Low Current , par. 6-20 Terminal 54 Low Voltage or
Terminal 54 Low Current for a time period defined in par. 6-00 Live Zero Timeout Time .
par. 6-22
If several time-outs occur simultaneously, the frequency converter prioritises the time-out functions
as follows:
Live Zero Timeout Function
1. Par. 6-01
Control Timeout Function
2. Par. 8-04
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
