6-4-1 PID Control Functions
Func. Name Description
F_102 PID Compensation Gain
․
Compensate the gain for pressure command
control under constant pressure control.
F_103
PID Control Mode
Selection
=0: Open-loop operation
*Disable the feedback signal from the pressure
transmitter.
=1: Forward control; D postposition
*When the actual pressure (PV) is lower than the setting
pressure (SV), the drive will start to accelerate.
*Forward control: When the system actual value is less
than the setting value, the drive will start to accelerate.
=2: Forward control; D preposition
*Forward control: When the system actual value is less
than the setting value, the drive will start to accelerate.
=3: Reverse control; D postposition
*Reverse control: When the system actual value is less
than the setting value, the drive will start to decelerate.
=4: Reverse control; D preposition
*Reverse control: When the system actual value is less
than the setting value, the drive will start to decelerate.
F_104 P Selection
=0: P postposition
=1: P preposition
F_105 Proportional Gain(P)
․
Set the gain value for deviation adjustment.
(0.0:
―P‖ control disabled)
*To adjust the stable time.
*Increase the value: Increase the response speed of
constant pressure control system.
*Decrease the value: Reduce the oscillation and response
speed.
F_106 Integration Time(I)
․
Set the integration time for deviation adjustment.
(0.0:
―I‖ control disabled)
*To adjust the error value at stable state.
*Increase the value: Reduce the error value. The
response speed of constant pressure control system will
be decreased.
*Decrease the value: The response speed of constant
pressure control will be increased, but the error amount
will be increased.
F_107 Derivative Time(D)
․
Set the derivative time for deviation adjustment.
(0.00:
―D‖ control disabled)
*To adjust the amount of overshooting.
*Increase the value: Reduce the overshooting of pressure,
but motor is easier vibration.
*Decrease the unstable vibration factor of motor, but the
pressure is easier overshooting.
F_108
Derivative Time of
Feedback
․
Set the derivative time for feedback signal.
F_111
Offset Adjustment for
Integration Time
․ Adjust the PID control offset.
