OTOR STATUS MONITORING
(MST)
Motor status monitoring function (MST) is designed to be the common place to set up all
necessary motor data and to select the used motor protection functions. Settings related
to the protection functions can be edited also inside of each function and after changed
they will be also updated into MST function. In addition to motor data settings MST
function counts motor starts, times motor start succeeded, times motor has been stopped,
running time, starting time, stopped time cumulatively and from last event separately.
Outputs of the MST function are output motor stopped, motor starting, motor running,
motor stalled, missing phase, load normal, overloading, and high overcurrent signals
which can be used in indication or in application logics. From these signals MST also
generates events if so wanted.
Figure 3.3.1-99 Simplified function block diagram of the MST function.
The MST function outputs are dependent on the set motor data. MST function outputs in
different kind of situations are presented in the following diagram.
