is the PID control reference.
F09.00
PID reference
channel
Setting range: 0～5
Default
value: 0
0: digital reference (F09.01)
1: AI1
2: AI2
3: HDI
4: multi-step speed
5: 485 communication
When the frequency source selects PID, the parameter decides the target
reference channel for the process PID. Reference target of the process PID is a
relative value, 100% of preset value corresponds to 100% of feedback value.
The system operates in relative value (0~100%).
F09.01
PID keypad
reference
Setting range: 0.0～100.0%
Default
value: 0.0%
When the PID reference channel (F09.00) is 0, this value is PID reference.
F09.02
PID feedback
channel
Setting range: 0～4
Default
value: 0
0: AI1
1: AI2
2: AI1+AI2
3: HDI
4: 485 communication
F09.03
PID direction
Setting range: 0～1
Default value: 0
0: positive
When the feedback signal is larger than the PID reference, the inverter output
frequency is required to decrease in order to make the PID to balance, such as
winding tension PID control.
1: negative
When the feedback signal is larger than the PID reference, the inverter output
frequency is required to increase in order to make the PID balance, such as
unwinding tension PID control.
