Spindle I am getting is 1.5kw air cooled locally and the vfd is sinamics v20 inverter from siemens. will they be ok
Water cooled spindles don't really have a Duty cycle and can be run for days without stopping.!!
Don't know the VFD but Siemens is good quality so provided it's rated correctly then you shouldn't have a problem.

Hi every one it has been a week now. I have assembled the frame.
I am running Mach3 Version R3.043.066
Every thing is running fine, but there is a problem. when a program is running or the machine is idle, motors rotates randomly. The motion is for fraction of a second. This can happen any time even when the machine is not running any g-code. I am unable to identify the problem. Please kindly help.
This will be electrical noise. Use shielded cable on all motors and signal cables and ground the shielding at one end only and take all grounds to a single point. Don't run single cables along side high power cables like Spindle power cable.
Don't fasten signal and power cables together using cable ties.
