6-26 Terminal 54 Filter Time Constant
Range:
0.001 s* [0.001 - 10.000 s]
6-27 Terminal 54 Live Zero
Option:

[1] * Enabled
4-86
Function:
Enter the high voltage value. This analog input scaling value should cor-
respond to the high reference/feedback value set in par.6-25
High Ref./Feedb. Value.
Function:
Enter the low current value. This reference signal should correspond to
the low reference/feedback value, set in par.6-24
Feedb. Value. The value must be set at >2 mA in order to activate the Live
Zero Timeout Function in par.6-01
Function:
Enter the high current value corresponding to the high reference/feed-
back value set in par.6-25 Terminal 54 High Ref./Feedb.
Function:
Enter the analog input scaling value that corresponds to the low voltage/
low current value set in par.6-20
6-22 Terminal 54 Low Current.
Function:
Enter the analog input scaling value that corresponds to the high voltage/
high current value set in par.6-21
6-23 Terminal 54 High Current.
Function:
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 con-
stant value improves dampening but also increases the time delay
through the filter.
This parameter cannot be adjusted while the motor is running.
Function:
This parameter makes it possible to disable the Live Zero monitoring. For
example, this to be used if the analog outputs are used as part of a de-
central I/O system (e.g., when used not as part of any adjustable fre-
quency drive related control functions, but for feeding a building
management system with data).
