Bias = 0%, Bias base point = 0%

PID process command

• PID command by communication (J02 = 4)

Communication parameter (S13): Transmission data 20000d/100% PID command.

PID Control Feedback Selection (E119)

• E119 = 0: Analog input terminal

If 0: Analog input terminal ([AI1], [AI2] AII function, [AI2] AIV function) is selected for PID Control

Feedback Selection (E119), allocate "5: PID feedback value" to the terminal used in feedback input

by any one of E61, E62 or E63. The analog input value is internally controlled as 0% to 100%. For

details on analog input, refer to 7-3-1 Analog Input Function Selection on page 7-35.

When analog input is applied to PID feedback, the following gains, biases, filters and offsets are appli-

Input terminal

AI2 (AII function)

AI2 (AIV function)

• E119 = 2: Modbus communication

If "2: Modbus communication" is set to PID Control Feedback Selection (E119), set a value in com-

munication parameter (S30) under the assumption of 20000d = 100%.

• E119 = 3: Pulse train frequency

If "03: Pulse train frequency" is set to PID Control Feedback Selection (E119), the inverter captures

a value converted into a percentage with the maximum frequency as 100% where the correction fac-

tor (d63/d62) is multiplied with the frequency value [kP/s] of the captured pulse train input.
