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 VFD is procedure PID
controlled.
The parameter determines the target given channel
during the PID procures.
0: Keypad digital given (P09.01)
1: Analog channel AI1 given
2: Analog channel AI2 given
3: Analog channel AI3 set
4: High speed pulse HDI set
5: Multi-step speed set
6: MODBUS communication set

The setting target of procedure PID is a relative one,
100% of the setting equals to 100% of the response of
the controlled system.
The system is calculated according to the relative value
(0
–100.0%).
Note:
Multi-step speed given, it is realized by setting
P10 group parameters.
