6-00 Live Zero Timeout Time
Range: Function:
10 s [1 - Enter the live zero timeout time period. Live zero
*
99 s] timeout time is active for analog inputs, that is,
terminal 53 or terminal 54, used as reference or
feedback sources. If the reference signal value
associated with the selected current input drops
below 50% of the value set in
parameter 6-10 Terminal 53 Low Voltage,
6-12 Terminal 53 Low Current,
parameter 6-20 Terminal 54 Low Voltage or
6-22 Terminal 54 Low Current for a time period
longer than the time set in parameter 6-00 Live
Zero Timeout Time, the function selected in
parameter 6-01 Live Zero Timeout Function is
activated.
6-01 Live Zero Timeout Function
Option: Function:
Select the time out function. The function set
in parameter 6-01 Live Zero Timeout Function is
activated if the input signal on terminal 53 or
54 is below 50% of the value in
parameter 6-10 Terminal 53 Low Voltage,
6-12 Terminal 53 Low Current,
parameter 6-20 Terminal 54 Low Voltage or
6-22 Terminal 54 Low Current for a time period
defined in parameter 6-00 Live Zero Timeout
Time. If several time outs occur simultaneously,
the frequency converter prioritises the time
out functions as follows
1. Parameter 6-01 Live Zero Timeout
Function
2. 8-04 Control Timeout Function
The output frequency of the frequency
converter can be:
•
[1] frozen at the present value
•

•
[3] overruled to jog speed
•
[4] overruled to max. speed
•
[5] overruled to stop with subsequent
trip
