the low reference/feedback value set in
parameter 26-14 Term. X42/1 Low Ref./Feedb.
Value.
26-11 Terminal X42/1 High Voltage
Range: Function:

Value.
26-14 Term. X42/1 Low Ref./Feedb. Value
Range: Function:

26-15 Term. X42/1 High Ref./Feedb. Value
Range: Function:

value set in parameter 26-11 Terminal
X42/1 High Voltage.
26-16 Term. X42/1 Filter Time Constant
Range: Function:
NOTICE

s]
This parameter cannot be adjusted
while the motor is running.
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.
26-17 Term. X42/1 Live Zero
Option: Function:
This parameter makes it possible to enable the
live zero monitoring, example, where the analog
input is the frequency converter control, rather
than being used as a decentral I/O system, such
as a building management system.
