Connecting the CNC control unit to servo amplifiers via a

high-speed serial bus (FANUC Serial Servo Bus, or FSSB), which

uses only one fiber optics cable, can significantly reduce the amount

of cabling in machine tool electrical sections.

Axis settings are calculated automatically according to the

interrelationships between axes and amplifiers entered on the FSSB

setting screen. Parameter Nos. 1023, 1905, 1910 to 1919, 1936, and

1937 are specified automatically according to the results of the

calculation.

The FSSB setting screen displays FSSB-based amplifier and axis

information. This information can also be specified by the operator.

1. Press function key

To enter data, place the machine in MDI mode or the emergency stop state,

position the cursor to the point where a desired item is to be input, then

enter the desired data and press soft key [INPUT] (or the

INPUT

key on the

MDI panel).

When soft key [SET] is pressed after data has been entered, a warning

message is displayed if the entered data contains an error. When the data

is satisfactory, the corresponding parameter is set up.

To restore the previous value of a parameter if, for example, an entered

value is incorrect, press soft key [READ].

When the power is turned on, values are read from the parameters and

displayed on the screen.

CAUTION

1

For the parameters to be specified on the FSSB setting

screen, do not attempt to enter values on the parameter

screen using the MDI or a G10 command. Use only the

FSSB screen to enter values for these parameters.

2

If pressing soft key [SET] results in a warning message

being displayed, retry data entry, or press soft key [READ]

to clear the warning message. Note that pressing the reset

key does not clear the warning message.
