*1. This setting is enabled when the Digital Operator with the volume control (Model: 3G3AX-OP01) is connected.
*2. When the PID function is enabled, the data unit differs between read and write operations.
Set parameter values in units of 0.01 Hz for writing and in units of 0.1% (as 100% of the maximum frequency)
for reading.
