Stop Error Detection

Description

If after giving the Stop command, due to welded contactor, if the motor does not stop, in such cases, motor stop error detection function gives the trip signal to stop the motor in alternate way.

This function monitors the current after the Stop signal is set. If any of the three phase currents is still present for the time specified in time delay setting, after the Stop signal is set, then the function triggers a trip signal.

NOTE: Make sure that the motor stop error detection trip signal is configured to any of the TeSys Tera digital output to control the alternate contactor or to inform upstream devices.
