Consulting signals for the spindle.

REVOK
There is a mark for each spindle. The mnemonics for each spindle are the following:
REVOK1 (can also be programmed as REVOK)
REVOK2
It indicates whether the actual (real) spindle rpm match the ones programmed (=1) or not
(=0). In other words, whether they are within the percentages set by (a.m.p.) UPSPDLIM and
LOSPDLIM.
• When the spindle is stopped, M5, REVOK is (=1).
• With M3 and M4, the CNC sets this mark high (=1) when the actual spindle rpm match
the ones programmed.
• When working in closed loop (M19 or G63), the CNC sets this mark low (=0) while the
spindle is moving and high (=1) when the spindle is in position.
The REVOK signal may be used to handle the Feedhold signal and avoid machining at lower
or higher rpm than desired.
SYNCMASTER
There is a mark for each spindle. The mnemonics for each spindle are the following:
SYNCMASTER1
This mark is activated at the master spindle and indicates that a synchronization has begun
with the #SYNC instruction. When activating a synchronization, the CNC activates the
ENABLE signal at both spindles and waits for the SERVOON signal (if DWELLis used).
When a spindle synchronization is active, the PLCCNTL, INHIBIT and SPDLEREV signals
of both master and slave are ignored. Likewise, while threading, only the feedback and
reference signal of the main spindle are taken into account.
SYNCHRON
There is a mark for each spindle. The mnemonics for each spindle are the following:
SYNCHRON1
This mark is activated at the slave spindle and indicates that a synchronization has begun
with the #SYNC instruction. When activating a synchronization, the CNC activates the
ENABLE signal at both spindles and waits for the SERVOON signal (if DWELLis used).
When a spindle synchronization is active, the PLCCNTL, INHIBIT and SPDLEREV signals
of both master and slave are ignored. Likewise, while threading, only the feedback and
reference signal of the main spindle are taken into account.
SYNCHRONP
There is a mark for each spindle. The mnemonics for each spindle are the following:
SYNCRONP1
This mark is activated at the slave spindle and indicates that a position synchronization has
begun. This mark may be used to distinguish between synchronization in position or in
velocity and to know which mark, SYNSPEED or SYNCPOSI, to attend to.
SYNSPEED
There is a mark for each spindle. The mnemonics for each spindle are the following:
SYNSPEED1
This mark is activated at the slave spindle when it is synchronized in speed.
This mark is set to (=0) when exceeding the maximum speed error allowed, whose default
value is set by machine parameter DSYNCVELW.
