3.8 Parameters: 6-** Main Menu - Analog
In/Out
3.8.1 6-0* Analog I/O Mode
Parameter group for setting up the analog I/O congu-
ration.
The frequency converter is equipped with 2 analog inputs:
•
Terminals 53.
•
Terminals 54.
The analog inputs can be allocated freely 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 - 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. A
minimum of 1 V or 2 mA is
required to trigger the Live Zero.
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:
6-01 Live Zero Timeout Function
Option: Function:
•
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.
The function can also be activated
for a time period dened in
parameter 6-00 Live Zero Timeout
Time. 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
Timeout Function.
[0] * O
[1] Freeze output Frozen at the present value. Live
zero timeout time does not apply
to freeze output.
[2] Stop Overruled to stop.
[3] Jogging Overruled to jog speed.
[4] Max. speed Overruled to maximum speed.
[5] Stop and trip Overruled to stop with subsequent
trip.
