Illustration 3.8 Live Zero Timeout Function
3.7.2 6-1* Analog Input 53
Parameters for conguring the scaling and limits for analog
input 53 (terminal 53).
6-10 Terminal 53 Low Voltage
Range: Function:
0.07 V* [0 - 10 V] Enter the voltage (V) that
corresponds to
parameter 6-14 Terminal 53 Low Ref./
Feedb. Value. To activate
parameter 6-01 Live Zero Timeout
Function, set the value to >1 V.
6-11 Terminal 53 High Voltage
Range: Function:
10 V* [0 - 10 V] Enter the voltage (V) that
corresponds to the high reference
value (set in
parameter 6-15 Terminal 53 High
Ref./Feedb. Value).
6-12 Terminal 53 Low Current
Range: Function:
4 mA* [0 - 20 mA] Enter the low current value. This
reference signal corresponds to the
low reference/ feedback value that
is set in parameter 6-14 Terminal 53
Low Ref./Feedb. Value. To activate
parameter 6-01 Live Zero Timeout
Function, set the value to >2 mA.
6-13 Terminal 53 High Current
Range: Function:
20 mA* [0 - 20 mA] Enter the high current value
corresponding to the high
reference/feedback set in
parameter 6-15 Terminal 53 High
Ref./Feedb. Value.
6-14 Terminal 53 Low Ref./Feedb. Value
Range: Function:
Size
related*
[-4999 -
4999 ]
Enter the reference or feedback
value that corresponds to the
voltage or current set in
parameter 6-10 Terminal 53 Low
Voltage to parameter 6-12 Terminal
53 Low Current.
6-15 Terminal 53 High Ref./Feedb. Value
Range: Function:
200* [-4999 -
4999 ]
Enter the reference or feedback
value that corresponds to the
voltage or current set in
parameter 6-11 Terminal 53 High
Voltage to parameter 6-13 Terminal
53 High Current.
6-16 Terminal 53 Filter Time Constant
Range: Function:
0.01 s* [0.01 - 10 s] Enter the time constant. This
constant is a rst-order digital low-
pass lter time constant for
suppressing electrical noise in
terminal 53. A high time constant
value improves dampening, but
also increases the time delay
through the lter.
6-19 Terminal 53 mode
Select whether terminal 53 is used for current or voltage input.
Option: Function:
[0] Current mode
[1] * Voltage mode
3.7.3 6-2* Analog Input 54
Parameters for conguring the scaling and limits for analog
input 54 (terminal 54).
6-20 Terminal 54 Low Voltage
Range: Function:
0.07 V* [0 - 10 V] Enter the voltage (V) that
corresponds to the low reference
value (set in
parameter 6-24 Terminal 54 Low Ref./
Feedb. Value). To activate
