VFD Help needed - what braking options?
I have just installed a 1/4 HP VFD driving a 1/6 HP motor on the table of a surface grinder. The table runs back and forth with the VFD cycling the motor forward and reverse. It reverses kind of slow with the default settings - 6 secs & coast to stop. How quickly can I have it stop and with how much braking before I start to tax the limits of the VFD or shorten it's life considering the toll which the repetitive back and forth might have on it.
Brake starting frequency - 60 cps or less
Braking level 0% to 100%
Braking time 0.01 to 30 secs
There is also an option for automatic deceleration control (regeneration prevention).
The manual also says that a braking resistor will not work on this drive.
