7.6.11.3
P 5.12.5.1 PID Proportional Gain
Use this parameter to enter the process controller proportional gain. Quick control is obtained at high amplification. However, if
amplification is too great, the process may become unstable.
Default value:
0.01
Parameter
733
number:
Data type:
uint16
P 5.12.5.1 PID Proportional Gain
Use this parameter to enter the process controller integral time. Obtain quick control through a short integral time, though if the integral
time is too short, the process becomes unstable. An excessively long integral time disables the integral action.
Default value:
9999.00
Parameter
734
number:
Data type:
uint32
P 5.12.5.4 Antiwindup Enabled
Use this parameter to control error regulation. To continue regulation of an error even when the output frequency cannot be increased
or decreased, select [0] Off. To cease regulation of an error when the output frequency can no longer be adjusted, select [1] On.
Default value:
1 [On]
Parameter
731
number:
Data type:
enum
The following are the selections for the parameter:

P 5.12.5.5 PID Differentiation Time
Use this parameter to enter the process controller differentiation time. The differentiator does not react to constant error. It provides gain
proportional to the rate of change of the process feedback. Setting this parameter to zero disables the differentiator.
Default value:
0.00
Parameter
