3.8 Main Menu - Analog In/Out - Group 6

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 configuration.
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)
NB!
Thermistors may be connected to either an analog or a digital input.

6-00 Live Zero Timeout Time

Range:
10 s* [1 - 99 s]
6-01 Live Zero Timeout Function
Option:
[0] * Off
[1] Freeze output
[2] Stop
[3] Jogging
[4] Max. speed
[5] Stop and trip
Function:
Enter the Live Zero Time-out time period. Live 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 par. 6-10
Low Voltage Terminal 53 Low Current
, par. 6-12
Terminal 54 Low Current
par. 6-22
Timeout Time
, the function selected in par. 6-01
Function:
Select the time-out function. The function set in par. 6-01
vated if the input signal on terminal 53 or 54 is below 50% of the value in par. 6-10
Low Voltage Terminal 53 Low Current
, par. 6-12
Terminal 54 Low Current
par. 6-22
If several time-outs occur simultaneously, the frequency converter prioritises the time-out functions
as follows:
Live Zero Timeout Function
1. Par. 6-01
Control Timeout Function
2. Par. 8-04
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
