Status
The Programmer’s Status menu shows a live-readout of parameter values. This is extremely useful when fine-tuning the system or
carrying out diagnostic work. The table below gives details of the parameters that may be viewed.
Some of the menu items have additional functions that can be accessed via the
recorded minimum and maximum values relate to the lifetime of the controller.
and
buttons. The options that display
The functions, 2.9 Motor Demand and 2.10 Motor %on, also display further status information. This information is displayed in
place of the usual units shown on the screen. See Further Status Information for more details.
