Selecting Parameters
Within each function group, the parameter is changed in order (or in reverse
order) each time the
M key is pressed. (In the Calibration function group,
however, parameters cannot be changed in reverse order.) For details, refer to
Parameter Functions & Definitions on page 5-1.
Figure 3.5 — Parameters
Changing Parameters and Loading Values into Controller Memory
If you press the
M key at the final parameter, the display returns to the top
parameter for the current function group.
To change parameter value or configuration (setup), modify the setting by
using the
U or D key, and either leave the setting alone/unchanged for at
least 2 seconds or press the
M key. This loads the present value displayed into
the controller’s memory.
When another function group is selected, the parameter and value on the
display are the ones currently loaded into controller memory.
When you turn the controller power OFF, ensure that the values are loaded
into memory by pressing the
M key. The values and parameters setups are
sometimes not changed (loaded) by merely pressing the
U or D key.
