The inverter monitors the state of the motor
continuously even during the magnetic flux
period. So the magnetic flux can be used in
the motor stop, as well as to change the
rotation speed of the motor. Its other
advantages are:
Brake immediately after the stop command. It
does not need to wait the magnetic flux
weaken.
The cooling is better. The current of the stator
other than the rotor increases during
magnetic flux braking, while the cooling of the
stator is more effective than the rotor.

When the frequency command selection
(P00.06, P00. 07) is 7 or the voltage setting
channel selection (P04.27) is 6, the running
mode of the inverter is procedure PID
controlled.
The parameter determines the target given
channel during the PID procures.

The setting target of procedure PID is a
relative one, 100% of the setting equals to
100% of the response of the controlled
system.
