4 Explanation of Interface Signals
4.1 PLC Input Signals (Bit Type: X***)
Cont. Signal name
A Hob axis delay excess
[Function]
This signal informs that after the spindle rotation speed synchronization is completed in the tool spindle synchronization II
(Hobbing), the hob axis tracking delay between the actual position and the commanded position has exceeded the
allowable delay angle.
Note
(1) This signal uses the 1st spindle signal regardless of the hob spindle's number.
[Operation]
This signal turns ON when:
 The spindle rotation speed synchronization has been completed and the maximum delay angle of the hob axis (spindle)
exceeded the delay allowable angle set in the parameter "#3133 spherr".
This signal turns OFF when:
 The tool spindle synchronization II is canceled.
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 signal of the hob axis when the parameter "#1440 multi_sp_syn" (Multiple spindle synchronization valid)
is set to "1".

Cont. Signal name
A Holding power of spindle increased
[Function]
The increase holding power of spindle (disturbance observer) state is output to this signal.
[Operation]
This signal turns ON when the "Increase holding power of spindle" signal (EXOBS) turns ON and the spindle drive unit
enables the disturbance observer.
Turning OFF the "Increase holding power of spindle" signal (EXOBS) turns this signal OFF.
[Related signals]
(1) Increase holding power of spindle (EXOBS: Y1893)
