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: Function:
0.07 V* [0.00 - par. 6-21 V] Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value, set in par.6-24
Terminal 54 Low Ref./Feedb. Value .
6-21 Terminal 54 High Voltage
Range: Function:
10.00 V* [par. 6-20 - 10.00 V] Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par.6-25
Terminal 54 High Ref./Feedb. Value .
6-22 Terminal 54 Low Current
Range: Function:
4.00 mA* [0.00 - par. 6-23 mA] Enter the low current value. This reference signal should correspond to the low reference/feedback
value, set in par.6-24
Terminal 54 Low Ref./Feedb. Value . The value must be set at >2 mA in order
to activate the Live Zero Timeout Function in par.6-01
Live Zero Timeout Function .
6-23 Terminal 54 High Current
Range: Function:
20.00 mA* [par. 6-22 - 20.00 mA] Enter the high current value corresponding to the high reference/feedback value set in par.
6-25
Terminal 54 High Ref./Feedb. Value .
6-24 Terminal 54 Low Ref./Feedb. Value
Range: Function:
0.000 N/A* [-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the low voltage/low current value set in
par.6-20
Terminal 54 Low Voltage and par.6-22 Terminal 54 Low Current .
6-25 Terminal 54 High Ref./Feedb. Value
Range: Function:
100.000 N/
A*
[-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the high voltage/high current value set in
par.6-21
Terminal 54 High Voltage and par.6-23 Terminal 54 High Current .
6-26 Terminal 54 Filter Time Constant
Range: Function:
0.001 s* [0.001 - 10.000 s] 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.
