Parameters: 6-** Analog In/Out - Danfoss VLT Refrigeration Drive FC 103 Programming Manual

Parameter Description

3.8 Parameters: 6-** Analog In/Out

3.8.1 6-** Analog In/Out
Parameter group for configuration of the analog input and
output.
3.8.2 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:
•
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 [1 - Enter the live zero timeout in s. Live zero timeout
s 99 s] 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. 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.

Current.
The function can also be activated for a time
period defined 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.
Frozen at the present value. Live zero timeout
time does not apply to freeze output.
Overruled to stop.
Overruled to jog speed.
Overruled to stop with subsequent trip.
