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
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.

6-10 Terminal 53 Low Voltage
Range: Function:
0.07 V* [ 0 - par.
6-11 V]
Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
parameter 6-14 Terminal 53 Low Ref./Feedb.
Value.
6-11 Terminal 53 High Voltage
Range: Function:
10 V* [ par. 6-10
- 10 V]
Enter the high voltage value. This analog
input scaling value should correspond to the
high reference/feedback value set in
parameter 6-15 Terminal 53 High Ref./Feedb.
Value.
6-14 Terminal 53 Low Ref./Feedb. Value
Range: Function:
0* [-999999.999 -
999999.999 ]
Enter the analog input scaling value that
corresponds to the low voltage/low
current set in parameter 6-10 Terminal 53
Low Voltage and 6-12 Terminal 53 Low
Current.

Enter the analog input scaling

parameter 6-11 Terminal 53 High
Voltage and 6-13 Terminal 53 High
Current.
6-16 Terminal 53 Filter Time Constant
Range: Function:
0.001 s* [0.001 -

NOTICE
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.
