Setup: MACH 3, PDMX 126 BOB, PDMX 107 PWM spindle controller, Danfoss 2800 VFD with3 phase 400V input, ELTE 2.2KW air cooled spindle
The problem I am experiencing is that occasionally, and sporadically maybe 4-6 times a day it sounds like the spindle cuts out for a fraction of a second during operation. It's an audible blip, but resumes operartion immediately. Prior to this setup I was running a single phase 230V VFD powering a 2.2kw spindle without such blips, powered from the same circuit board. I have a 3 phase vacuum motor on the same supply which operates without symptoms.
I wonder if the VFD could be transmitting some noise to the motor. Would this translate to a very momentary cutout? Has anyone experienced anything similar? Any insight people could shed on this siyuation would be very much appreciated.
