Danfoss VLT FC 100 Series Programming Guide

6-25 Terminal 54 high ref./feedb. value
Range: Function:
100.000 Unit * [Par. 6-24 to
1000000.000]
Enter the analog input scaling value that corresponds to the high voltage/high current value set in par. 6-21 and
par. 6-23.
6-26 Terminal 54 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 54. 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.
6-27 Terminal 54 Live Zero
Option: Function:
[0] Disabled
[1]
*
Enabled 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)
3.8.5. 6-3* Analog Input 3 (MCB 101)
Parameter group for configuring the scale and limits for analog input 3 (X30/11) placed on option module MCB 101.
6-30 Term. X30/11 Low Voltage
Range: Function:
0.07 V * [0 - par. 6-31]
Sets the analog input scaling value to correspond to the low reference/feedback value (set in par. 6-34).
6-31 Term. X30/11 High Voltage
Range: Function:
10.0 V * [Par. 6-30 to 10.0 V]
Sets the analog input scaling value to correspond to the high reference/feedback value (set in par. 6-35).
6-34 Term. X30/11 Low Ref./Feedb. Value
Range: Function:
0.000 Unit * [1000000.000 to par.
6-35]
Sets the analog input scaling value to correspond to the low voltage value (set in par. 6-30).
6-35 Term. X30/11 High Ref./Feedb. Value
Range: Function:
1500.000 Unit [Par. 6-34 to
1000000.000]
Sets the analog input scaling value to correspond to the high voltage value (set in par. 6-31).
6-36 Term. X30/11 Filter Time Constant
Range: Function:
0.001s * [0.001 - 10.000 s]
A 1
st
order digital low pass filter time constant for suppressing electrical noise on terminal X30/11.
Par. 6-36 cannot be changed while the motor is running.
6-37 Term. X30/11 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)
