3.8.1 6-0* Analog I/O Mode
Parameter group for setting up the analog I/O configuration.
The frequency converter is equipped with 2 analog inputs:
Terminal 53 and 54. The analog inputs can freely be allocated
to either voltage (0 - 10 V) or current input (0/4 - 20 mA)
NOTE
Thermistors may be connected to either an analog or a
digital input.
6-00 Live Zero Timeout Time
Range: Function:
10 s * [1 -
99 s]
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 Terminal 53
Low Voltage, par. 6-12 Terminal 53 Low Current,
par. 6-20 Terminal 54 Low Voltage or
par. 6-22 Terminal 54 Low Current for a time period
longer than the time set in par. 6-00 Live Zero
Timeout Time, the function selected in par. 6-01 Live
Zero Timeout Function will be activated.
6-01 Live Zero Timeout Function
Option: Function:
Select the time-out function. The function set in
par. 6-01 Live Zero Timeout Function will be
activated if the input signal on terminal 53 or 54
is below 50% of the value in par. 6-10 Terminal 53
Low Voltage, par. 6-12 Terminal 53 Low Current,
par. 6-20 Terminal 54 Low Voltage or
par. 6-22 Terminal 54 Low Current for a time
period defined in par. 6-00 Live Zero Timeout
Time. If several time-outs occur simultaneously,
the frequency converter prioritises the time-out
functions as follows:
1. Par. 6-01 Live Zero Timeout Function
2. Par. 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

6-02 Fire Mode Live Zero Timeout Function
Option: Function:
The function set in par. 6-01 Live Zero Timeout
Function will be activated if the input signal
on analogue inputs is below 50% of the value
defined in parameter group 6-1* to 6-6*
"Terminal xx Low Current” or “Terminal xx
Low Voltage" for a time period defined in
par. 6-00 Live Zero Timeout Time.
