6-41 Terminal X30/12 High Voltage
Range:
10.00 V* [par. 6-40 - 10.00 V]
6-44 Term. X30/12 Low Ref./Feedb. Value
Range:
0.000 N/A* [-999999.999 - 999999.999 N/A]
6-45 Term. X30/12 High Ref./Feedb. Value
Range:
100.000 N/ [-999999.999 - 999999.999 N/A]
A*
6-46 Term. X30/12 Filter Time Constant
Range:
0.001 s* [0.001 - 10.000 s]
6-47 Term. X30/12 Live Zero
Option:
[0] * Disabled
[1] * Enabled
Function:
Sets the analog input scaling value to correspond to the low reference/feedback value set in par.
Term. X30/12 Low Ref./Feedb. Value
6-44
Function:
Sets the analog input scaling value to correspond to the high reference/feedback value set in par.
Term. X30/12 High Ref./Feedb. Value
6-45
Function:
Sets the analog output scaling value to correspond to the low voltage value set in par.6-40
X30/12 Low Voltage
.
Function:
Sets the analog input scaling value to correspond to the high voltage value set in par.6-41
X30/12 High Voltage .
Function:
st
A 1 order digital low pass filter time constant for suppressing electrical noise on terminal X30/12.
Term. X30/12 Filter Time Constant
par.6-46
Function:
This parameter makes it possible to disable Live Zero monitoring. For example, this may be used if
the analog outputs are used as part of a decentral I/O system (e.g., when not part of any adjustable
frequency drive-related control functions, but feeding a building management system with data).
