Goals and Symptoms

We've applyed ATS48D32Q on thread cutting lathe drive. In special case, they need immediate reverse. With dynamic braking we were able to stop device for 3-5 sec, because of high inertia. But this is too long time for this application. Now, Is it possible provide immediate reverse by the switch reverse line or by-pass contactor if ATS is in run mode? May we try it without damage power parts?

Facts and Changes

immediate reverse

Causes and Fixes

The ATS don't respond to this application, I propose you to use an ATV with braking resistor. You can also stop the motor in free wheel mode , inverse a motor phase ( see user manual ) and restart the motor with a long acceleretion ramp ( adjust the current limitation )
