Stopping oiler when machine is idle

[mmurray70]

Hi Tom,

Is there any easy way to detect when the machine is idle for a period of time? Would be nice if I could disable the oiler after say 10 mins of no movement. Thanks.

Control the Oiler via a relay contact on your VFD, so it comes on when the VFD starts the motor, and fit an electronic timer configured to give a 10min delay off when the contact opens on the VFD.

Hi Mark,

You might do something similar to how KStep is disabled after a period of no motion. Enable the Oiler and TimeStamp the time whenever there is motion, and if the current time is a certain amount past the TimeStamp then disable the oiler.

	for (;;) // loop forever
	{
		WaitNextTimeSlice();
		
		// Service Amplifier disable after no activity for a while
		if (ch0->Dest != LastX || ch1->Dest != LastY || ch2->Dest != LastZ)
		{
			// we moved - enable KStep Amplifers
			SetBit(45);
			T0 = Time_sec();  // record the time and position of last motion
			LastX=ch0->Dest;
			LastY=ch1->Dest;
			LastZ=ch2->Dest; 
		}
		else
		{
			if (Time_sec() > T0 + 10.0) ClearBit(45);
		}
	}

Thanks Tom, Worked perfectly.
