13.11 Spindle Synchronization Control ll
 Starting spindle synchronization
The spindle synchronization mode is entered by inputting the spindle synchronization signal (SPSY). The synchronized
spindle will be controlled in synchronization with the rotation speed commanded for the reference spindle during the spindle
synchronization mode.
When the difference of the reference spindle and synchronized spindle rotation speeds reaches the spindle synchronization
rotation speed reach level setting value (#3050 sprlv), the spindle rotation speed synchronization complete signal (FSPRV)
will be output.
The synchronized spindle's rotation direction is designated with the spindle synchronization rotation direction designation as
the same as the reference spindle or the reverse direction.

The spindle synchronization mode is entered when this signal
SPSY
turns ON.
This is turned ON when the difference of the reference spindle and
synchronized spindle rotation speeds reaches the spindle rotation
speed reach level setting value during the spindle synchronization
mode.
FSPRV
This signal is turned OFF when the spindle synchronization mode
is canceled, or when an error exceeding the spindle rotation
speed reach level setting value occurs during the spindle synchro-
nization control mode.
Designate the reference spindle and synchronized spindle rota-
tion directions for spindle synchronization.
0: The synchronized spindle rotates in the same direction of the
-
reference spindle.
1: The synchronized spindle rotates in the reverse direction of the
reference spindle.
