APPENDIX 5.1 Differences with virtual mode switching method
Differences between virtual mode switching method and advanced synchronous
control method are shown in Table 5.1 below.
Table 5.1 Differences between virtual mode switching method and advanced synchronous
control method
Item
Virtual mode switching method
Advanced synchronous control method
Starting method
The whole system is switched to the virtual mode
by turning ON the real/virtual mode switching
request bit.
The control is started for each axis by turning ON
the synchronous control start bit for each axis.
General
Stopping method
The whole system is switched to the real mode
by turning OFF the real/virtual mode switching
request bit.
The control is stopped for each axis by turning
OFF the synchronous control start bit of each
axis.
Number of settings
per output axis
Total 3 axes of main shaft (2 axes) and auxiliary
input (1 axis)
