2.2.5.2 WAIT FOR MOTOR DEMAGNETIZING
When the drive is switched off it is dangerous to switch on immediately, due to the unknown magnetic
flux position that could produce a motor over–current. The only chance it's to wait the time needed for
the magnetic flux to reduce itself with its time constant that depend on the motor type and can vary
from few milliseconds to hundreds of milliseconds.
For this reason has been introduced the parameter P28 that set the wait time after power switch off
after that, it's possible to switch on the power another time: also if the user gives the RUN command
during this wait time, the drive waits to complete it before enabling another time the power.
Parameter P28 is defined in time units of 100us so the default value 10000 correspond to 1 second.
