Parameter Descriptions

3.8 Parameters: 6-** Analog In/Out

3.8.1 6-0* Analog I/O Mode
The analog inputs can freely be allocated to be either
voltage (FC 301: 0..10 V, FC 302: 0..± 10 V) or current (FC
3 3
301/FC 302: 0/4..20 mA) input.
NOTICE
Thermistors may be connected to either an analog or a
digital input.

Function:
Enter the live zero timeout time period. 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 6-10 Terminal 53
Low Voltage, 6-12 Terminal 53 Low Current,
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 6-01 Live Zero Timeout
Function is activated.
Function:
Select the timeout 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,
parameter 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 timeouts occur
simultaneously, the frequency converter
prioritises the timeout functions as follows:
1. Parameter 6-01 Live Zero Timeout
Function.
2. Parameter 8-04 Control Word Timeout
Function.
Frozen at the present value.
Overruled to stop.
Overruled to jog speed.
Overruled to stop with subsequent trip.
