Control action type selection (1. oS, 2. oS)
Use to select Direct action/Reverse action.
Data range:
0: Direct action
1: Reverse action
Factory set value:
Input 1_control action type selection (1. oS): 1
Input 2_control action type selection (2. oS): 1
Control action type:
Direct action:
The Manipulated output value (MV) increases as the Measured value (PV)
increases. This action is used generally for cool control.
Reverse action: The Manipulated output value (MV) decreases as the Measured value (PV)
increases. This action is used generally for heat control.
Integral/Derivative time decimal point position selection (1.IddP, 2.IddP)
Use to select a decimal point position of Integral time and Derivative time in PID control.
Data range:
0: No decimal place
1: One decimal place
2: Two decimal places
Factory set value:
Input 1_integral/derivative time decimal point position selection (1.IddP): 2
Input 2_integral/derivative time decimal point position selection (2.IddP): 2
Related parameters:
Integral time (P. 37), Derivative time (P. 37)
Derivative gain (1. dGA, 2. dGA)
Use to set a gain used for derivative action in PID control. Derivative gain should not be changed under ordinary
operation.
Data range:
0.1 to 10.0
Factory set value:
Input 1_derivative gain (1. dGA): 6.0
Input 2_derivative gain (2. dGA): 6.0
Under ordinary operation, it is not necessary to change Derivative gain set value.
