I have two Magnum 400 10/20 drivers running two stepper motors. Peak power consumption is about 2 kW.
In the event of a power failure on the 3-phase supply, I'd like to trigger a controlled emergency stop. Sudden uncontrolled stop could be fatal to the worm drive in the equipment, due to inertia on the other end.
But that means I have to supply power for an additional two seconds or so to control the motors during deceleration ramp.
How can I do that? Is there some sort of 3-phase UPS or generator that can kick in and do the job?
