Clausing Drill Press 460V question

[micromind]

All VFDs have what is called a 'carrier frequency'. This is the frequency of the DC pulses generated by the VFD.

Most VFDs have a parameter that can adjust the carrier frequency. Higher = less noise but it's harder on the motor. If it's a basic standard motor, I'd leave it alone. If the motor is wound with spike-resistant magnet wire, it'll be ok to increase it.

Further, higher carrier frequencies will cause more bearing fluting. This is where ball bearings will fail early because they carry current from the rotor to the frame. Every VFD will cause this but higher carrier frequencies will accelerate the wear.

I’ve got the 2hp one

Change the drive's deceleration settings to decelerate more slowly, or set it to free wheel on stop. The drive can't decelerate the motor fast enough at the highest speed. Deceleration requires the drive to absorb the energy from the motor, it can't do it very well without a breaking resistor.

Great information, thank you!

I will give this a shot, thank you!

Since the TECO L510 will stay on the grinder, I need to figure out what I'm getting for the drill press. I'm looking at a KBAC or KBDA since they already come in an enclosure. Do I want the KBAC (analog with parameters set via wires in the enclosure), or the KBDA, (digital with an interface on the front for programming). Is one a better application for the drill press? Price is within $5 of each other.
