Parameter Descriptions
26-36 Term. X42/5 Filter Time Constant
Range: Function:
NOTICE
0.005 s [0.005 - 10 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 X42/5. A high
time constant value improves
dampening, but also increases the
time delay through the filter.
26-37 Term. X42/5 Live Zero
Option: Function:
Enable or disable the live zero
monitoring.
[0] Disabled

Parameters for configuring the scaling and output function
for analog output, terminal X42/7.

Option: Function:
Set the function of terminal X42/7
as an analog current output.

Sensor 4
Function:
[0 - 200 %] Scale the minimum output of the
selected analog signal at terminal
X42/7 as a percentage of the
maximum signal level. For 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.
