Answer / maheshreddy

Start Limitation: It is the limitation from the Motor
Design side. There is a limitraion for motor from No.of
Consecutive hot Stat and Consecutive Cold Stat according to
motor themal withstandabulity.

Answer / shivani

Start limitation means no. of start this is bercause if
consecutively u start the motor the motor got heated&
thermal conductivity will dec. .not goo for its health.
Start interlock means
frequency,voltage& powerrequirement we can control by
different relay so. after fullfilling those constraints
only it should start for giving poptimal performance.
