I am upgrading a mill currently that has a maximum spindle RPM of 8000. I am using a Hitachi VFD with a 25 ohm 500W braking resistor. From maximum speed, deceleration under 15 seconds is causing a fault. I would like to know how to decrease deceleration time to closer to 5 seconds. I am playing with the idea of connecting two brake resistors in parallel to do this, but am currently unsure if it will help.
Any insight would be appreciated.
