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
in 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.
