Function:
Enter the high voltage value. This analog input
scaling value should correspond to the high
reference/feedback value set in par. 6-15.
6-14
Terminal 53 Low Ref./Feedb.
Value
Value:
-1000000.000 to par. 6-15
0.000 Unit
Function:
Enter the analog input scaling value that cor-
responds to the low voltage/low current set in
par. 6-10 and 6-12.
6-15
Terminal 53 High Ref./Feedb.
Value
Value:
Par. 6-14 to
1000000.000
100.000 Unit
Function:
Enter the analog input scaling value that cor-
responds to the high voltage/high current val-
ue set in par. 6-11/6-13.
6-16
Terminal 53 Filter Time Con-
stant
Value:
0.001 - 10.000 s
0.001s
Function:
Enter the time constant. This is a first-order
digital low pass filter time constant for sup-
pressing electrical noise in terminal 53. A high
time constant value improves dampening but
also increases the time delay through the fil-
ter.
This parameter cannot be adjusted while the
motor is running.
6-17 Terminal 53 Live Zero
Value:
Disabled [0]
Enabled [1]
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 fre-
quency converter related control functions,
but feeding a Building Management system
with data)
