Parameter Descriptions

6.7 Parameters: 6-** Analog In/Out

Parameter group for configuration of the analog input and
output.
6.7.1 6-0* Analog In/Out Mode
Parameter group for setting up the analog In/Out configu-
ration.
The frequency converter is equipped with 2 analog inputs:
Terminal 53 and 54. The analog inputs on the frequency
converter can freely be allocated to either voltage (-10 V to
+10 V) or current input (0/4 to 20 mA).
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 Word Timeout Function

6.7.2 6-1* Analog Input 1
Parameters for configuring the scaling and limits for
analog input 1 (terminal 53).
NOTE
Analog input 53 is preset for usage with "open loop"
control on 0-10 V. Terminal 54 is preset for "Process Loop"
control using a pressure sensor AKS with a pressure range
of -1 : 12 bar.
