4 Protective Elements
4.2 Motor Starting and Control Module
• Trip state.
Under normal conditions, the motor operations should go through stop, start, run, and
stop cycles that are referred to as a complete operation sequence; while under certain
abnormal conditions, the motor could go from start to stop, or start to trip, or run to trip.
If other protection trips occur at either the start or run cycle, the motor will be forced to
go to trip mode. After motor currents are terminated, the motor will go into the stop cycle.
A motor start is blocked by the hidden state "Block" as shown in the motor start diagram,
if any of the following conditions are noted – motor starts limit, starting frequency,
thermal and mechanical constraints.
