Position deviation in the position loop mode of the fourth spindle
DGN
NOTE For DGN417 to 424, information obtained from the serial
spindle control unit is directly displayed.
425
First–spindle synchronization error [Pulse]
DGN
426
Second–spindle synchronization error [Pulse]
DGN
427
Third–spindle synchronization error [Pulse]
DGN
428
Fourth–spindle synchronization error [Pulse]
DGN
DGN425 – 428 : Indicates the absolute value of a synchronization error in
synchronization mode where each spindle is treated as a
slave axis.

SS4 SS3 SSR SIC
SIC Indicates whether a module necessary for spindle serial control
(third and fourth spindles) has been installed, as follows:
0: Not installed
1: Installed
SSR 0: Spindle serial control (third and fourth spindles) not in progress.
1: Spindle serial control (third and fourth spindles) in progress.
SS3 0: Specifies not to use the third spindle under spindle serial control.
1: Specifies to use the third spindle under spindle serial control.
SS4 0: Specifies not to use the fourth spindle under spindle serial
control.
1: Specifies to use the fourth spindle under spindle serial control.
431
Alarm status of the third serial spindle
DGN
432
Alarm status of the fourth serial spindle
DGN
433
Third spindle motor temperature [_C]
DGN
434
Fourth spindle motor temperature [_C]
DGN
The αi spindle motor coil temperature is indicated.
When the system configuration of the spindle (even another spindle)
includes an additional spindle older than the αi spindle, this function is
invalid.
This temperature is used as a guideline for occurrence of the spindle
overheat alarm.
