Consulting and modifiable signals of the spindle.<br />
Execution channels<br />
4 Once the gear change is over, it cancels the indicator (M1002) and it lets the CNC know<br />
by setting AUX<strong>EN</strong>D high (=1).<br />
(GEAR change completed) = RES M1002<br />
The AUX<strong>EN</strong>D mark must be kept high (=1) longer than the time period set by g.m.p.<br />
MINA<strong>EN</strong>DW so the CNC cancels the MSTROBE mark and concludes the gear change.<br />
PLCCNTL<br />
SANALOG<br />
There is one signal for each spindle. The mnemonics for each spindle are the following:<br />
PLCCNTL1 (can also be programmed as PLCCNTL)<br />
PLCCNTL2 PLCCNTL3 PLCCNTL4<br />
SANALOG1 (can also be programmed as SANALOG)<br />
SANALOG2 SANALOG3 SANALOG4<br />
These signals are used with analog spindles, position-Sercos, velocity-Sercos and<br />
Mechatrolink.<br />
When the PLC sets the PLCCNTL mark high (=1), the spindle decelerates with a ramp until<br />
it stops and it is then controlled by the PLC. The SANALOG register sets the spindle<br />
com<strong>man</strong>d voltage to be applied. The spindle control via PLC is used, for example, for<br />
oscillating the spindle during a gear change.<br />
Analog spindle.<br />
10 V of velocity com<strong>man</strong>d correspond to SANALOG = 32767. In other words:<br />
For 4V, program SANALOG = (4x32767)/10 = 13107<br />
For 4V, program SANALOG = (-4x32767)/10 = -13107<br />
Velocity-Sercos spindle.<br />
The com<strong>man</strong>d in SANALOG will be given in 0.0001 rpm.<br />
Sercos spindle in position.<br />
The com<strong>man</strong>d in SANALOG will be given in 0.0001 degrees.<br />
Mechatrolink spindle.<br />
The com<strong>man</strong>d in SANALOG will be given in hundredths of a Hertz.<br />
The com<strong>man</strong>d indicated in SANALOG is not applied with a ramp; therefore, it is up to the<br />
PLC program to apply the com<strong>man</strong>d gradually when necessary.<br />
The spindle reference point is not lost when the spindle is controlled via PLC. There is no<br />
need to home the spindle again when its control is switched back to the CNC.<br />
The PLC has no priority over a spindle synchronization. When attempting to control a<br />
synchronized spindle (either master or slave) using PLCCNTL, a warning will be issued<br />
indicating that it is not possible. Also, if the gear change of a synchronized spindle involves<br />
a com<strong>man</strong>d from the PLC, this change will not be possible.
