UI freezes frequently

Hey Brian,

@IronCreek

Mine isn’t freezing, but since I added a spindle it goes black intermittently.

This is a new topic, since it’s not the “User interface freezes” issue, but the “Monitor is intermittent” issue.

@Aiph5u

in the first one would place the ferrite cores on the Monitor’s HDMI cable, best at both ends, especially if you have the monitor intermittent issue.

If the problem persists, you should be aware that…

@Aiph5u

a VFD and especially its output cable, the cable to the three-phase spindle, are heavy sources of EMI. Therefore it is required to use shielded cables, also a VFD is intended to be installed into an earthed electrical cabinet. Both should be indicated in your VFD manual, including which wires to use, on a page that should look like shown here . As you can see there,

• for the signal cables like used for ModBus communication, you should use shielded, twisted pair cable.
• On the output of the VFD, i.e. the spindle cable, you should use shielded 3+PE for the three-phase spindle, like shown here:

And finally to not only prevent EMI but also to comply EN/IEC 60204-1 safety standard, the machine should be electrically bonded and grounded,
