Functionality
An emergency condition can arise in cases where the motor needs to be started despite
knowing that this can increase the temperature above limits or cause a thermal
overload that can damage the motor. The emergency start-up function ESMGAPC
allows motor start-ups during such emergency conditions. ESMGAPC is only to force
the protection relay to allow the restarting of the motor. After the emergency start
input is activated, the motor can be started normally. ESMGAPC itself does not
actually restart the motor.
The function contains a blocking functionality. It is possible to block function outputs,
timer or the function itself.
Analog channel configuration
ESMGAPC has one analog group input which must be properly configured.
