1. A Start command is given.
2. We recommend that you use start
magnetisation to build rotor flux fast and
to decrease the time when the motor can
produce nominal torque.
3. When the start magnetisation time is
over, the system lets the the frequency
reference go to the open frequency limit.
4. The mechanical brake opens. The
frequency reference stays at the open
frequency limit until the brake
mechanical delay is over, and the correct
brake feedback signal is received.
