Goals and Symptoms
We have an ATS48 - 630 kW
Fan application ( diam = 2 meters )
Probably 1500 rpm
How to stop it in a delay of 15 sec max ?
Causes and Fixes
Regarding the application it's not possible ( sure at 99 % ) to stop it in 15 sec and with an inverter it's the same. The only possible solution is to reverse the rotation with a timer between the two directions and use the second parameters range ( by auxiliary contact ) and adjust the ILT to a low value, with this system the current limitation will control the deceleration. But we can't affirm the 15 sec, some test are necessary. An external breaking system should be present to help the ATS at the end of the ramp and verify if the motor will support this operation.
Please follow the attached diagram.
