3.8.4 6-2* Analog Input 2
Parameters for configuring the scaling and limits for analog input 2 (terminal 54).
6-20 Terminal 54 Low Voltage
Range:
0.07 V* [0.00 - par. 6-21 V]
6-21 Terminal 54 High Voltage
Range:
10.00 V* [par. 6-20 - 10.00 V]
6-22 Terminal 54 Low Current
Range:
4.00 mA* [0.00 - par. 6-23 mA]
6-23 Terminal 54 High Current
Range:
20.00 mA* [par. 6-22 - 20.00 mA]
6-24 Terminal 54 Low Ref./Feedb. Value
Range:
0.000 N/A* [-999999.999 - 999999.999 N/A]
6-25 Terminal 54 High Ref./Feedb. Value
Range:
100.000 N/ [-999999.999 - 999999.999 N/A]
A*
6-26 Terminal 54 Filter Time Constant
Range:
0.001 s* [0.001 - 10.000 s]
Function:
Enter the low voltage value. This analog input scaling value should correspond to the low reference/
Terminal 54 Low Ref./Feedb. Value
feedback value, set in par.6-24
Function:
Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par.6-25
Function:
Enter the low current value. This reference signal should correspond to the low reference/feedback

value, set in par.6-24
to activate the Live Zero Timeout Function in par.6-01
Function:
Enter the high current value corresponding to the high reference/feedback value set in par.
Terminal 54 High Ref./Feedb. Value
6-25
Function:
Enter the analog input scaling value that corresponds to the low voltage/low current value set in
par.6-20 Terminal 54 Low Voltage
Function:
Enter the analog input scaling value that corresponds to the high voltage/high current value set in
par.6-21 Terminal 54 High Voltage
Function:
Enter the time constant. This is a first-order digital low pass filter time constant for suppressing
electrical noise in terminal 54. A high time constant value improves damping, but also increases the
time delay through the filter.
This parameter cannot be adjusted while the motor is running.
