I have a problem with my vertical cnc machine , is and old 1981 geared toyoda

Usually when the weather is cold , I use to have problems starting the spindle , in order to make it eork , I used low speed 100 rpm , 200 rpm , 400 rpm 800 rpm.......only then , worked correctly and continuously .

Until , a few days ago , not work at all.

I applied hot air in the driver , and worked again a little.

A technician , check the driver circuits , and found out there were a few problems with soldering , after resolving this problem. I installed again the driver and stop working completly, the red alarm led is on , spindle alrm red led on , and I can't start the control only the monitor , with a no ready signal.

What can I do??

Tks a lot!!
