[ 2 ] PID command by analog inputs (J02 = 1)
When any analog input (voltage input to terminals [12] and [V2], or current input to terminal [C1]) for PID command 1 (J02
= 1) is used, it is possible to arbitrary specify the PID command by multiplying the gain and adding the bias. The polarity
can be selected and the filter time constant and offset can be adjusted. In addition to J02 setting, it is necessary to select PID
command 1 for analog input (specified by any of E61 to E63, function code data = 3). For details, refer to the descriptions of
E61 to E63.

„ Offset (C31, C36, C41)
C31, C36 or C41 configures an offset for an analog voltage/current input. The offset also applies to signals sent from the
external equipment.
„ Filter time constant (C33, C38, C43)
C33, C38, and C43 provide the filter time constants for the voltage and current of the analog input. Choose appropriate
values for the time constants considering the response speed of the machinery system, as large time constants slow down the
response. If the input voltage fluctuates because of noise, specify large time constants.
„ Polarity (C35, C45)
C35 and C45 specify the input range for analog input voltage.
