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 valid than the rotor.
P09 Group PID control
P09.00
PID reference
source
selection
When the frequency command selection (P00.06, P00. 07) is 7,
the running mode of the inverter is procedure PID control.
The parameter determines the channel used as the
reference during the PID procedure.
0 : Keypad digital reference (P09.01)
1 : Analog channel AI1 reference
2 : Analog channel AI2 reference
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 reference is realized by
setting P10 group parameters

P09.01
Keypad PID
preset
When P09.00=0, set the parameter whose basic value is the
feedback value of the system.
The setting range: -100.0%~100.0%
0.0% ○
P09.02
PID feedback
source
selection
Select the PID channel by the parameter.
1 : Analog channel AI2 feedback
4 : MODBUS communication feedback
Note : The reference channel and the feedback channel can
not coincide, otherwise, PID can not control effectively.

P09.03
PID output
feature
selection
0 : PID output is positive . When the feedback signal
exceeds the PID reference value, the output frequency of the
inverter will decrease to balance the PID. For example, the
strain PID control during wrapup
1: PID output is negative. When the feedback signal is
stronger than the PID reference value, the output frequency
of the inverter will increase to balance the PID. For example,
the strain PID control during wrapdown
