Hello;
We have checked it we have the relay with the diode across the input power.We have basically two CNC machine.Spindle not stopping after G code ends problem in one machine.
Also we have checked the shielded cable we have shielded wire from the power end but not doing shielded across the spindle side.But this type of arrangements in on both the CNC machine i.e not shielded from the spindle side.But one CNC machine's spindle stop properly and the other CNC machine is not stopping unless or until we have to press the emergency button to stop the machine??? Why
and thanks for your reply
Yes the software spindle control setup is same on both the machines i.e- MACH 3 MILL. and we have check the relay also its on by M3 and stop also on M5 but the spindle stop very slowly and the value of frequency in VFD not decrease as like as that of other CNC.What do you think either its the spindle's motor old or some other problem???
Yes if you need to add a Braking Resistor then you would use the 40ohm, you will have to adjust parameters in the VFD also, you may not need this, but they are always worth while addition
Have you checked that the 0-10v PWM from the control board to the VFD is also stopping / shutting off, when you go from M3 to M5 you need to check this with a meter also
Parameters to check
F0.06= ? ( 5 would be normal without a Braking Resistor fitted )
F0.07=1
F2.02=0
F2.03=12 ( a starting point )
F2.04=20
F2.05=5
