NOTICE
Thermistors may be connected to either an analog or a
digital input.
6-00 Live Zero Timeout Time
Range: Function:
10
s
*
[0 -
99 s] Enter the live zero timeout in s. Live zero 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
•
Parameter 6-12 Terminal 53 Low Current
•
Parameter 6-20 Terminal 54 Low Voltage
•
Parameter 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 timeout function. If the input signal
on terminal 53 or 54 is below 50% of the value
in
•
Parameter 6-10 Terminal 53 Low Voltage
•
Parameter 6-12 Terminal 53 Low Current
•
Parameter 6-20 Terminal 54 Low Voltage
•
Parameter 6-22 Terminal 54 Low Current
for a time period defined in parameter 6-00 Live
Zero Timeout Time , then the function set in
parameter 6-01 Live Zero Timeout Function is
activated.
If several timeouts occur simultaneously, the
frequency converter prioritizes the timeout
functions as follows:
1. Parameter 6-01 Live Zero Timeout
Function
.
2. Parameter 8-04 Control Word Timeout
Function
.

[5] Stop and
trip Overruled to stop with subsequent trip.

reference value, set in
parameter 3-02 Minimum Reference . Set the
value to exceed 2 mA in order to activate the
live zero timeout function in
parameter 6-01 Live Zero Timeout Function .
