Example similar to the one used for GEAR1 through GEAR4<br />
The spindle oscillation during a gear change is controlled by the PLC. Gear 4 is requested<br />
while gear 1 is active.<br />
The example for the GEAR1 through GEAR4 signals describes how to detect and carry out<br />
the gear change. This example shows how to control the spindle oscillation during a gear<br />
change.<br />
The PLC sets SANALOG to the value corresponding to the residual velocity com<strong>man</strong>d and<br />
activates the PLCCNTL mark to indicate that the spindle is controlled by the PLC.<br />
When done, the PLCCNTL mark must be set low (=0) and the SANALOG signal must be<br />
set to "0".<br />
SPDLEREV<br />
There is a mark for each spindle. The mnemonics for each spindle are the following:<br />
SPDLEREV1 (can also be programmed as SPDLEREV)<br />
SPDLEREV2 SPDLEREV3 SPDLEREV4<br />
When the PLC sets this mark high (=1), the CNC reverses the spindle turning direction. To<br />
do this, it decelerates and accelerates applying the ramps set by machine parameters. This<br />
mark is only taken into account when the spindle works in open loop.<br />
If an M2 or M4 function is executed while the SPDLEREV mark is high (=1), the spindle will<br />
turn in the opposite direction to the one assigned to the function.<br />
If the PLC activates or cancels the SPDLEREV mark when the spindle is controlled by the<br />
PLCA (PLCCNNTL mark active), the CNC does not generate ramps to invert the SANALOG<br />

The PLC offers a mark for each spindle. The mnemonics for each spindle are the following:<br />
Here is an example of the mnemonics for PLCM3; it is the same for the rest of the spindles.<br />
PLCM3SP1 (can also be programmed as PLCM3)<br />
PLCM3SP2 PLCM3SP3 PLCM3SP4<br />
The PLC turns this mark on to let the CNC know that it must execute the corresponding M<br />
function at the indicated spindle. The spindle must belong to a channel, M functions cannot<br />
be sent to spindles that are not assigned to any channel. The PLC may change the spindle<br />
