I've got a 90's QT20 with T-plus, looks like a mitsubishi MDS-A-SP-260 spindle drive. Running on a phase converter and when the spindle ramps up at program start it seems to "kick" an internal breaker or something and the control powers off. Doesn't happen when manually increasing the speed, only when commanded high and "go" is hit.

Can I change the ramp with a parameter on the control or drive? I've seen threads about dip switches and whatnot but they don't seem to apply to this drive. The manuals I've downloaded don't seem to speak to acceleration.

Thanks!
 
For the T/M-Plus, spindle accel/decel parameter in the control is SP33. Make it a big number, like 3000 to 5000. You may have to be in privileged mode (1131) to change it....?

Also, you may have to power the control down and back up for the changes to take. You can easily see the accel/decel changes, watching the spindle spin up and down.
