Parameter Description

3.8 Parameters 6-** Analog In/Out

3.8.1 6-0* Analog I/O Mode
Parameter group for setting up the analog I/O configu-
ration.
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)
NOTICE
Thermistors may be connected to either an analog or a
digital input.
6-00 Live Zero Timeout Time
Range: Function:
10 s [1 - Enter the Live Zero Time-out time period. Live
*
99 s] 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
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 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 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,
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 time-outs occur simulta-
neously, the frequency converter prioritises the
time-out functions as follows
1. Parameter 6-01 Live Zero Timeout
Function
2. Parameter 8-04 Control Timeout
Function
The output frequency of the frequency
converter can be:
