Danfoss VLT FC 100 Series Programming Guide

6-14 Terminal 53 Low Ref./Feedb. Value
Range: Function:
0.000 Unit * [-1000000.000 to par.
6-15]
Enter the analog input scaling value that corresponds to the low voltage/low current set in par. 6-10 and par.
6-12.
6-15 Terminal 53 High Ref./Feedb. Value
Range: Function:
100.000 Unit * [Par. 6-14 to
1000000.000]
Enter the analog input scaling value that corresponds to the high voltage/high current value set in par. 6-11 and
par. 6-13.
6-16 Terminal 53 Filter Time Constant
Range: Function:
0.001s * [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 53. A high time constant value improves dampening but also increases the time delay through the
filter.
This parameter cannot be adjusted while the motor is running.
6-17 Terminal 53 Live Zero
Option: Function:
This parameter makes it possible to disable the Live Zero monitoring. E.g. to be used if the analog outputs are
used as part of a decentral I/O system (e.g. when not part of any frequency converter related control functions,
but feeding a Building Management system with data)

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:
0.07V * [0.00 – par. 6-21]
Enter the low voltage value. This analog input scaling value should correspond to the low reference/feedback
value, set in par. 6-24.
6-21 Terminal 54 High Voltage
Range: Function:
10.0V * [Par. 6-20 to 10.0 V]
Enter the high voltage value. This analog input scaling value should correspond to the high reference/feedback
value set in par. 6-25.
6-22 Terminal 54 Low Current
Range: Function:
4 mA * [0.0 to 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. The value must be set at >2 mA in order to activate the Live Zero Time-out Function in par. 6-01.
6-23 Terminal 54 High Current
Range: Function:
20.0 mA * [Par. 6-22 to - 20.0 mA]
Enter the high current value corresponding to the high reference/feedback value set in par. 6-25.
6-24 Terminal 54 Low Ref./Feedb. Value
Range: Function:
0.000 Unit * [-1000000.000 to par.
6-25]
Enter the analog input scaling value that corresponds to the low voltage/low current value set in par. 6-20 and
par. 6-22.
