Parameter Description

3.8 Main Menu - Analog In/Out - Group 6

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 (0-10V) or current input
(0/4-20mA)
NOTE
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 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 6-00 Live Zero Timeout Time, the function
selected in 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 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 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 defined in
6-00 Live Zero Timeout Time. If several time-outs
occur simultaneously, the frequency converter
prioritises the time-out functions as follows
1. 6-01 Live Zero Timeout Function
2. 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
