PHASE ERROR 2 (degree)
(excluding phase shift calc.)
[Function]
This signal informs the phase error (value excluding the phase error memorized with the spindle
synchronization phase shift calculation function) when the phase synchronization (with R
command) or the "Phase shift calculation request" signal (Y435) is ON. The phase error is output by
1 ° increment.
The data has no meaning in cases other than above.
[Operation]
When the phase synchronization (with R command) or the "Phase shift calculation request" signal
(Y435) is ON, and when the speeds of the basic spindle and the synchronous spindle are constant,
the phase error between the basic spindle and the synchronous spindle is output.

— CLOCK DATA
[Function]
The year, month, date, hour, minute and second data is informed by the controller to the PLC as the
current clock information.
[Operation]
The date and time data is output as shown below. The data is output as binary data.
