- 210 -
NOTE
4 The CNC can control up to eight spindle amplifiers with the serial interface. When
the spindle 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 sixteen spindles, or
thirty two 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 eight spindles.)
Parameters of the spindle amplifier with the serial interface correspond to the
above functions as follows:
(1) Serial spindle parameters for the first to eighth spindles:
No.4000to4539 ”S1”to“S8”
(2) Parameter No.4000 to No.4175 "S1" to "S8":
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 "S1" to "S8":
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 "S1" to "S8":
When the spindle switching function is not provided, or for the main spindle
when the function is provided.
Parameters No.4284 to No.4351 "S1" to "S8":
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.
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.4539 "S1" to "S8") 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.)
