Function:
Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
parameter 26-34 Term. X42/5 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
parameter 26-35 Term. X42/5 High Ref./Feedb.
Value.
Function:
Enter the analog input scaling value that
corresponds to the low-voltage value set
in parameter 26-30 Terminal X42/5 Low
Voltage.
Function:
Enter the analog input scaling value
that corresponds to the high-voltage
value set in parameter 26-21 Terminal
X42/3 High Voltage.
Function:
NOTICE
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 X42/5. A high time constant
value improves dampening, but also
increases the time delay through the
filter.
Function:
Enable or disable the live zero monitoring.

Function:
Set the function of terminal X42/7 as an
analog current output.
0–100 Hz, (0–10 V).
Minimum reference–maximum reference,
(0–10 V).
-200% to +200% of

0–torque limit (parameter 4-16 Torque
Limit Motor Mode), (0–10 V).
0–motor rated torque, (0–10 V).
0–motor rated power, (0–10 V).
0–speed high limit (parameter 4-13 Motor
Speed High Limit [RPM] and
parameter 4-14 Motor Speed High Limit
[Hz]), (0–10 V).

0–100%, (0–10 V).
Function:
Scale the minimum output of the selected analog
signal at terminal X42/7, as a percentage of the
maximum signal level, example, if 0 V (or 0 Hz) is
required at 25% of the maximum output value,
program 25%. Scaling values up to 100% can
never be higher than the corresponding setting in
parameter 26-42 Terminal X42/7 Max. Scale.
