5.2.3 OPERATING MODE DESCRIPTION
The FUNC key is used to access the parameters organized in five groups. Use the FUNC
pushbutton to access the Group 1 parameters; the last entry (showing Group and nonE ) is intended
to access the other groups of parameters, or pressing FUNC again returns to the normal display
mode. Each group has its own family of parameters, loosely grouped around the decreasing need to
change the parameters. Each group (except Group 9) also has the ability to load its own default
parameters and the default values of the lower number groups.
To reset a specific group (and lower numbered groups) to the default factory settings, press the
FUNC key until nonE and GROUP show on the display. Press the ▲ key until the appropriate group
number appears in the upper display. Press the FUNC key to enter the appropriate group. Press the
FUNC key until DEFLT shows on the lower display and OFF shows on the upper display. Press the
▼ or ▲ key until ON # (where # is the Group number). Press the FUNC key to load the factory
parameters for that group (and lower numbered groups; for example selecting Group 5 resets groups
1, 2, 3, 4 and 5).
5.3 SETTING THE INSTRUMENT’S BASIC CONFIGURATION
The example below shows those parameters by group, which will permit an ATC770 to control a
motor. A modification of any other of the default parameters is not needed. Please note in the Value
column, the final values used in your process for future set-up use.
