Detailed instruction of parameters
braking strength.
The inverter can slow down the motor by increasing the
magnetic flux. The energy generated by the motor during
braking can be transformed into heat energy by increasing
the magnetic flux.
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.
This function code is used to adjust the displayed current of
the AC input side.
Setting range: 0.00~1.00
P09 Group PID control
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 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. Inverters ≤ 15 kW can be
set by the digital potentiometer on the keypad and AI1
setting is not available for the devices ≥ 18.5 kW
2: Analog channel AI2 reference
3: Analog channel AI3 reference
4: High speed pulse HDI reference
5: Multi-step speed set
6: MODBUS communication set
7~9: Reserved
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.
When P09.00=0, set the parameter whose basic value is
the feedback value of the system.
The setting range: -100.0%~100.0%
Select the PID channel by the parameter.
0: Analog channel AI1 feedback. Inverters ≤15kW can be
set by the digital potentiometer on the keypad and AI1
setting is not available for the devices ≥ 18.5kW
