Notes on parameters of the spindle amplifier with the serial interface
NOTE
1 Among the parameters of the spindle amplifier with the serial interface, parameters Nos. 4015
and 4191 cannot be changed by the users.
These parameters require to assign optional software to the CNC and are automatically set
depending on the type of the software.
2 To set the parameters of the spindle amplifier with the serial interface automatically, set #7 of
parameter No.4019 (if the sub spindle is set in the CNC with the spindle switching function, use
parameter No.4195) to 1, assign the model code of the motor to be used to parameter No.4133
(if the sub spindle is set in the CNC with the spindle switching function, use parameter No.4309),
turn off the power of the CNC and spindle amplifier, and restart the CNC and spindle amplifier.
3 Parameters No.4000 to No.4351 are used in the processing on the spindle amplifier. See
FANUC AC SPINDLE MOTOR α series PARAMETER MANUAL (B65150E) and FANUC
AC SPINDLE SERVO UNIT serial interface S series MAINTENANCE MANUAL (B65045E).
4 The CNC can control up to two spindle amplifier with the serial interface. If twopath control is
in use, two spindle amplifiers (one for path 1 and the other for path 2) can be controlled.
A spindle amplifier can be controlled in the Series 16 performing singlepath control. When the
spindle control amplifier provides the spindle switching function, one spindle amplifier can
control two spindle motors using the switching function.
The output switching function can be used in spindle motors to be connected.
Up to four spindles, or eight types, (or, for the Series 16 performing singlepath control, up to
two spindles, or 4 types) can be used by switching the spindle motors. (The number of spindles
that can controlled simultaneously is the same as the number of spindle amplifiers, that is two
spindles (or, for the Series 6 performing singlepath control, a spindle).) Parameters of the
spindle amplifier with the serial interface correspond to the above functions as follows:
(1) Parameter No.4000 to No.4351 S1: First spindle amplifier
(2) Parameter No.4000 to No.4175 : When the spindle switching function is not provided, or for
the main spindle in the spindle amplifier when the function is provided.
Parameter No.4176 to No.4351 : For the sub spindle in the spindle amplifier when the
spindle switching function is provided.
(3) Parameters at low speed when the output switching function is provided.
Parameters No.4136 to No.4175 : When the spindle switching function is not provided, or
for the main spindle when the function is provided.
Parameters No.4284 to No.4351 : For the sub spindle when the spindle switching function
is provided.
5 The CNC stores the parameters of the spindle amplifier with the serial interface. The CNC sends
them to the spindle amplifier at the system power on and they are used in the unit.
These parameters are sent from the CNC to the spindle amplifier in a batch when:
The CNC is switched on.
The serial spindle is restarted by a reset that is carried out after spindle communication
alarm 749 occurs (because the spindle control unit is switched off or because of noise).
If these parameters are rewritten, they are sent from the CNC to the spindle amplifier
sequentially when:
The parameters have been entered from the MDI.
The parameters have been entered as programmable (G10).
The parameters have been entered via the reader/punch interface.
To set parameters automatically, upload parameters corresponding to the motor model from
the spindle amplifier to the CNC prior to the procedure specified above.
The parameters of the spindle amplifier with serial interface can be changed after the
system starts. Changing the parameters (No.4000 to No.4351) in the CNC sends them to
the spindle amplifier at an appropriate time and the parameters in the unit are updated. Be
careful not to change parameters incorrectly.
