Function:
Enter the analog input scaling
value that corresponds to the high
voltage value set in 26-11 Terminal
X42/1 High Voltage.
Function:
Enter the time constant. This is a first-
order digital low pass filter time constant
for suppressing noise in terminal X42/1. A
high time constant value improves
dampening but also increases the time
delay through the filter.
NOTE
This parameter cannot be adjusted
while the motor is running.
Function:
This parameter makes it possible to enable the
Live Zero monitoring. E.g. where the analog input
is a of the frequency converter control, rather
than being used as of a decentral I/O system,
such as a Building Management System.
Function:
0 - par. Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
26-24 Term. X42/3 Low Ref./Feedb. Value.
Function:
Enter the high voltage value. This analog
input scaling value should correspond to
the high reference/feedback value set in
26-25 Term. X42/3 High Ref./Feedb. Value.
Function:
Enter the analog input scaling value
that corresponds to the low voltage
value set in 26-20 Terminal X42/3 Low
Voltage.
