Setup: All setups
Data type: Int32
Enter the analog input scaling value that corresponds to the low-voltage value set in parameter 26-20 Terminal X42/3 Low Voltage.
26-25 Term. X42/3 High Ref./Feedb. Value
Default value: 100
Setup: All setups
Data type: Int32
Enter the analog input scaling value that corresponds to the high-voltage value set in parameter 26-21 Terminal X42/3 High Voltage.
26-26 Term. X42/3 Filter Time Constant
Default value:
0.005 s
Setup: All setups
Data type:
Uint16
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 X42/3. A high value of time constant improves
dampening, but also increases the time delay through the filter.
26-27 Term. X42/3 Live Zero
Default value:
[1] Enabled
Setup: All setups
Data type: Uint8
This parameter makes it possible to enable the live zero monitoring, for example, where the analog input is the drive control, rather than
being used as a decentral I/O system, such as a building management system. If set for temperature and used as feedback, set the unit
for either Celsius or Fahrenheit.

6.26.5 26-3* Analog Input X42/5
This parameter group contains parameters for configuring the scaling and limits for analog input terminal X42/5.
26-30 Terminal X42/5 Low Voltage
Default value:
0.007 V
