Table 18.11: Description of the PID controller setpoint automatic adjustment
P930 Description
0
It defines that, in the transition of the PID controller operation mode from manual to automatic, the control setpoint value (P911)
will not be uploaded with the present value of the control process variable (P916), and, in the transition of the PID controller
operation mode from automatic to manual, the setpoint value of the PID controller in manual mode (P918) will not be uploaded
with the present value of the motor speed (P002)

P931 – PID Controller Proportional Gain
P932 – PID Controller Integral Gain
P933 – PID Controller Derivative Gain
Adjustable
Range:
0.00 to 99.99 Factory
Setting:
P931 = 1.00
P932 = 5.00
P933 = 0.00
Properties:
Description:
These parameters define the gains of the PID controller and must be set according to the magnitude or process
that is being controlled.
NOTE!
Table 18.3 on page 18-5 suggests setting values for the gains according to the process to be
controlled by the PID controller.
P934 – PID Controller Sampling Period
Adjustable
Range:
0.050 to 9.999 s
Factory
Setting:
0.100 s
Properties:
Description:
This parameter defines the sampling time of the PID controller.
NOTE!
Table 18.3 on page 18-5 suggests setting values for the sampling time according to the process to
be controlled by the PID controller.
