- 301 -
NOTE
4 The CNC can control up to four spindle amplifiers (three spindle amplifiers for
Series 18i/180i/180is) 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 eight spindles, or sixteen 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 four spindles.) Parameters of the spindle
amplifier with the serial interface correspond to the above functions as follows:
(1) Parameter No.4000 to No.4539 "S1": First spindle amplifier
Parameter No.4000 to No.4539 "S2": Second spindle amplifier
Parameter No.4000 to No.4539 "S3": Third spindle amplifier
Parameter No.4000 to No.4539 "S4" (only for Series 16i/160i/160is):
Fourth spindle amplifier
(2) Parameter No.4000 to No.4175 "S1"/"S2"/"S3"/"S4": 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"/"S2"/"S3"/"S4": 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"/"S2"/"S3"/"S4": 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"/"S2"/"S3"/"S4": 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/puncher 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", "S2",
"S3","S4") 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.)
6 The fourth spindle amplifier can be used just in Series 16i/160i/160is.
