Hello,

When powering up and running the spindle for about 30s, its runs so very hot that you cant keep you hand over the spindle for a couple seconds! The spindle is rated for 8A and the VFD is rate at 10A. There is something I dont have correct as it seems the spindle is being electrically overloaded!

I have gone through 2 VFDs now thinking that my VFD was defective but I get the same result so its definitely something I am doing wrong!



VFD Info

I have attached the VFD manual but it can also be seen online.

VFD Settings:

P0-000 = 0 [Select command source - set to keyboard control]

P0-001 = 0 [Select frequency source - set to main frequency]

P0-002 = 0 [Main frequency source - set to keyboard potentiometer]

P0-003 = 0 [Assistant frequency source - set to keyboard potentiometer]

P0-004 = 400 [Keyboard digital setting frequency]

P0-005 = 5 [Jog frequency]

P0-006 = 1 [Running direction - set to 1 to run the spindle clockwise]

P0-007 = 400 [Upper frequency]

P0-008 = 0 [Lower frequency]

P0-009 = 8 [Accelerate speed time]

P0-010 = 8 [Decelerate speed time]

P0-011 = 6 [Carrier frequency]

P0-012 = 1 [V/F curve setting - set to 50Hz motor, general load]

P0-013 = 3 [Torque boost]

P0-014 = 100 [Automatic torque compensation gain]

P0-015 = 100 [Automatic slip compensation gain]

P0-031 = 0 [Stop mode]

P0-035 = 80 [Protection current of motor overload - set to 80% of VFD rated amps as motor is rated for 8A]

P0-036 = 150 [Over-current protection value when losing steps]

P0-037 = 130 [Over-voltage protection value when losing speed]



Spindle Info

Spindle being used is a GDZ-80F-2.2KW Air-Cooled Spindle
