PID Control

To enable PID control, set PID selection (n084) to "Enabled", according
to the description below.
LED Setting
0
1 Enabled D=Fdbk
2 Enabled D=Fdfwd
3 Enabled Rev Fdbk
Then select the PID control setpoint value and detected feedback value
setpoint as follows:
· Setpoint Value Selection
The control circuit terminal FV voltage signal (0 to 10V) or multi-step
speed parameters n024 to n027 can be used to select the PID setpoint
value.
Control circuit terminal FV voltage signal:
Set operation mode selection (n002) to "SEQ=OPR REF=TRM" or
"SEQ=TRM REF=TRM".
Multi-step speed constants (n024 to n027):
Set operation mode selection (n002) to "SEQ=OPR REF=OPR" or
"SEQ=TRM REF=OPR".
(combination of multi-step speed reference and jog frequency reference)
· Detected Value Setting
The control circuit terminal FI current signal (4 to 20mA) or voltage
signal (0 to 10V) can be used to set the PID detected value.
Control circuit terminal FI current signal:
Set aux. analog input selection (n044) to "4-20mA".
Control circuit terminal FI voltage signal:
Set operation mode selection (n044) to "0-10VDC".
(Cut jumper J1 on the control PCB board.)
