Detailed instruction of parameters
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
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
1: Analog channel AI2 feedback
2: Analog channel AI3 feedback
3: High speed HDI feedback
4: MODBUS communication feedback
5~7: Reserved
Note: The reference channel and the feedback channel can
not coincide, otherwise, PID can not control effectively.
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
