Group 34: Process Variables - ABB ACS 400 User Manual

Group 34: Process Variables

Parameters of this group can be used to create custom process variables. Values of process
variables can be seen in parameters 0134
the ACS-PAN output display. Value is calculated by taking given parameter from the operating data
group (Group 1), and multiplying and dividing it with given coefficients. The unit and number of
decimal digits is configurable.
See example below.
