B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 213 -
NOTE
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.
If bit 4 (WSP) of parameter No. 8703 is set to 0, the CNC does not immediately
perform data transfer to the spindle amplifier even when data has been written to a
parameter by using the PMC window function. So, the new parameter value set by
rewriting does not become valid automatically. To perform data transfer
immediately, set bit 4 (WSP) of parameter No. 8703 to 1.
If you want to change such parameter settings during automatic operation, use
programmable parameter input (G10).
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") 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.
