General consulting signals.
This way, if a block contains functions S1000 and S1=550 and the value of SPDLTIME
parameter of both spindles is other than zero, the CNC will transfer the following information
to the PLC.
SSTROBE
There is a mark for each spindle. The mnemonics for each spindle are the following:
SSTROBE1 (can also be programmed as SSTROBE)
SSTROBE2 SSTROBE3 SSTROBE4
The CNC channel sets this mark high (=1) to indicate to the PLC that a new spindle speed
has been selected. The CNC channel only uses this mark on spindles whose SPDLTIME
parameter has a value other than zero.
DMxx
This mark is associated with some M auxiliary functions.
The marks associated with functions M00, M01, M02, M06, M08, M09, M30 have a mark
for each channel. Here is an example of the mnemonics for DM00; it is the same for the rest
of the marks (DM01, DM02, DM06, DM08, DM09, DM30).
DM00C1 (can also be programmed as DM00)
DM00C2 DM00C3 DM00C4
The marks associated with functions M03, M04, M05, M19, M41, M42, M43, M44 have a
mark for each spindle. Here is an example of the mnemonics for DM03; it is the same for
the rest of the marks (DM04, DM05, DM19, DM41, DM42, DM43, DM44).
DM03SP1 (can also be programmed as DM03)
DM03SP2 DM03SP3 DM03SP4
The CNC indicates in these marks the status of the spindle auxiliary M functions. The mark
is set to (=1) if the function is active and to (=0) if otherwise.
BLKSEARCH
There is a mark for each channel. The mnemonics for each channel are the following.
BLKSEARCHC1 (can also be programmed as BLKSEARCH)
BLKSEARCHC2 BLKSEARCHC3 BLKSEARCHC4
The CNC channel sets this mark high (=1) to indicate that the "Block Search" option is active
in the Automatic Operation mode.
ADVINPOS
There is a mark for each channel. The mnemonics for each channel are the following.
ADVINPOSC1 (can also be programmed as ADVINPOS)
ADVINPOSC2 ADVINPOSC3 ADVINPOSC4
The CNC channel sets this signal high for some time before the axes reach position. This
time is set by (g.m.p.) ANTIME.
If the total duration of the movement is lower than the value set by (g.m.p.) ANTIME, the mark
goes high (=1) immediately.
If (g.m.p.) ANTIME has been set to 0, the mark is always active.
It is used on punch presses that have an eccentric cam as a punching system. This signal
may be used to start the movement of the punch before the axes reach the position. This
reduces idle time, thus increasing the number of punches per minute.
