6-36 Term. X30/11 Filter Time Constant
Range: Function:
0.001 s* [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
Term. X30/11 Filter Time Constant 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).
[0] * Disabled
[1] * Enabled
3.8.6 6-4* Analog Input 4 MCB 101
Parameter group for configuring the scale and limits for analog input 4 (X30/12) placed on option module MCB 101.
6-40 Terminal X30/12 Low Voltage
Range: Function:
0.07 V* [Application dependant] Sets the analog input scaling value to correspond to the low reference/feedback value set in
par. 6-44
Term. X30/12 Low Ref./Feedb. Value .
6-41 Terminal X30/12 High Voltage
Range: Function:
10.00 V* [Application dependant] Sets the analog input scaling value to correspond to the high reference/feedback value set in
par. 6-45
Term. X30/12 High Ref./Feedb. Value .
6-44 Term. X30/12 Low Ref./Feedb. Value
Range: Function:
0.000 N/A* [-999999.999 - 999999.999 N/A] Sets the analog output scaling value to correspond to the low voltage value set in par. 6-40 Terminal
