Machine control
This unit offers the possibility to control the spindle as well as the inputs and outputs required for it.
2.5.1
Spindle Control
The Start Stop keys control the machine spindle.
Start spindle in m3.
Start spindle in m4.
Stop the spindle.
Note:
If the spindle is already turning, the m3 and m4 keys will speed up or slow down the spindle.
When starting or stopping the spindle, the machine will follow the programmed acceleration time.
The external JOG keys, M3 and M4, will work in the same way as the DRO keys.
2.5.1.1
Potentiometer Control
The spindle speed can be changed manually using an external potentiometer.
The potentiometer mode will turn on when the digital input called “Potentiometer on/off” is activated
(the icon indicates that the potentiometer mode is active). Then, the analog input will be assumed as
spindle velocity command. When exiting the potentiometer mode by deactivating the digital input
“Potentiometer on/off” and after stopping the spindle, the DRO will return to its previous state, either
RPM mode or CSS mode.
2.5.2
Range (gear) change.
When selecting a work range other than the current one,
the DRO waits for the user to change to the indicated
range (gear).
When using automatic range (gear) detection, the range
cannot be edited at the DRO, just change the range and
accept the confirmation of the change at the DRO.
The current range value will be read through inputs DM41,
DM42, DM43, DM44. The exact combination of inputs
DM41...DM44 for each range may be set by parameter.
If it detects that the gear has been changed while
machining, the spindle stops immediately and it cannot be
restarted until the range change is confirmed at the
DRO.
The DRO generates digital outputs in order to be able use an automatic gear change.
Outputs M41, M42, M43 and M44 indicate the range (gear) to change to (M41 indicates Gear 1, M42
indicates Gear 2, etc.), then, the STROBE signal to command the gear changer to act. It is also
possible to wait for the “M-done” signal as confirmation for the DRO that the gear change process is
completed successfully.
