NOTE
1 NS is the number of position feedback pulses per one
revolution of the motor (multiplied by four)
2 Even if the system employs a closed loop, bit 3 of parameter
2002 is 1 and bit 4 is 0.
(8)Reference counter
1821 Reference counter capacity for each axis (0 99999999)
Turn off the power then back on.
(9)FSSB display and setting screen
Connecting the control unit to servo amplifiers via a highspeed
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 FSSBbased amplifier and axis
information. This information can also be specified by the operator.
(This function cannot be used with the twopath control function of the
Power Mate iD.)
