D700 VFD Braking help

D700 VFD Braking help

D700 VFD Braking help

I am performing a durability test on some vehicle components. I have a Teeter-Totter table that is cycled using a 408 motor. For controls I am using a Mitsubishi D700 VFD with a 24 volt 3 pole control relay interrupting voltage between the VFD and the motor. This cycles twice a day for 70 minutes then sits for 8 then 16 hours. Also this is at -15°C so I dont want to use any additional air cylinders or anything.

Problem when the relay opens the motor coast down to a stop. I need it to stop in the horizontal position. I have a Prox sensor to monitor table location and would like to apply a break at that time. The motor is not moving very fast (48hz).

-The table could slow down before it stops (it doesn't have to stop on a dime just needs to stop horizontal.

Please let me know if you have any additional questions. Thanks in advance
