Cont. Signal name
Spindle synchronization: Phase offset
A
data
[Function]
With the spindle phase shift amount calculation function, the phase error of the reference spindle and synchronized
spindle is obtained and memorized by turning the PLC signal ON at executing the spindle synchronization. The
synchronized spindle can be rotated with the handle during the spindle phase shift calculation, so the phase relation
between two spindles can be adjusted by seeing.
If the "Spindle phase synchronous control" signal (SPPHS) is input while the "Phase offset request" signal (SSPHF) is ON,
the phase error will be aligned based on the position shifted by the memorized phase shift amount.
Such operation makes the phase alignment easy when clamping a profile material over.
[Operation]
The phase error memorized by the phase shift calculation is output.
Unit: 360°/4096
Note
(1) Refer to the signal of the 1st spindle when the parameter "#1440 multi_sp_syn" (Multiple spindle synchronization
valid) is set to "0".
(2) Refer to the synchronized spindle's signal when the parameter "#1440 multi_sp_syn" (Multiple spindle synchroniza-
tion valid) is set to "1".
(3) This data is output only during the spindle synchronous control.
[Related signals]
(1) Spindle phase synchronization (SPPHS: Y18B1)
(2) Phase shift calculation request (SSPHM: Y18B3)
(3) Phase offset request (SSPHF: Y18B4)
(4) Spindle synchronization: Phase error/Hob axis delay angle (R6516)
Cont. Signal name
Spindle synchronization: Phase error

monitor
[Function]
The phase error during the spindle phase synchronous state can be monitored.
[Operation]
The phase error during the spindle phase synchronous control is output by the pulse unit.
Note
(1) Refer to the signal of the 1st spindle when the parameter "#1440 multi_sp_syn" (Multiple spindle synchronization
valid) is set to "0".
(2) Refer to the synchronized spindle's signal when the parameter "#1440 multi_sp_syn" (Multiple spindle synchroniza-
tion valid) is set to "1".

(2) Spindle synchronization: Phase error monitor (upper limit) (R6521)
