Parameters for configuring the scaling and output function
for analog output, terminal X42/7.
3-176
Function:
par. 6-30 - Enter the high voltage value. This
analog input scaling value should
correspond to the high reference/
feedback value set in 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 26-30 Terminal
X42/5 Low Voltage.
Function:
Enter the analog input scaling
value that corresponds to the
high voltage value set in
26-21 Terminal X42/3 High
Voltage.
Function:
Enter the time constant. 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. This parameter
cannot be adjusted while the motor is
running.
Function:
This parameter makes it possible to enable the
live zero monitoring, for example where the
analog input is a part of the adjustable frequency
drive control, rather than being used as part of a
decentral I/O system, such as a building
management system.
