Not too far OT as this is a lathe motor.
Yaskawa 606 PC3 VFD 240V/3ph AC in & out driving a Baldor 5hp inverter-rated CNC lathe motor.
Had the inverter rebuilt, new caps, reinstalled and works fine, but now the motor rings on deceleration.
It does have a braking resistor in the circuit.
Cable from VFD to motor is short, under one meter in length.
I do have the PC3 manual, and I have studied it. It gets a bit complex for me in some chapters ;-)
I'm assuming that a decel-time parameter was reset. That, or I need to use an S-curve decel? Any ideas what parameter to play with and which way it needs to go?
In general, what's up with a 3ph AC motor on a short cable ringing?
Thanks for any thoughts.
