    I have some Electrocraft (now owned by Baldor) motors with tachs like that and they are glued on. If you look at the joint between the shaft and the rotor you may see the adhesive.

    That might be the answer. My Hitachi lists an input of 220V + or - 10% so I ended up with buck transformers to bring it down. Check your transformer or manual for proper input volts. 244V is just...

    Wild guess, does the VFD show any change when the M3 is issued?
