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

This parameter cannot be adjusted
while the motor is running.
Enter the time constant. This is a first-
order digital low pass filter time constant
for suppressing electrical noise in terminal
53. A high time constant value improves
dampening but also increases the time
delay through the filter.
