*1. This switches the frequency reference among the volume, current, and voltage based on the O/OI Selection
(A005) setting and the status of the multi-function input terminal allocated to 16 (AT: Analog input switching).
Here, volume represents the volume control (VR) on the optional Digital Operator (Model: 3G3AX-OP01).
*2. Setting the PID Selection (A071) to Enabled causes the analog input selection setting in A076 to be allocated
to the PID feedback function. When the 1st Frequency Reference Selection (A001) is set to 01 (Control circuit
terminal block), the analog input setting other than that selected in A076 is used as the target frequency refer-
ence. In this case, the setting in A005 and the function allocated to the terminal AT (Analog input switching)
are disabled.
*3. In A079, you can set a target value, or have a setting that overlaps with the PID Feedback Selection value.
With an overlapping setting, the analog input is used for both the feedback and feedforward signals.
*4. This parameter can be set to 02 (Analog voltage input) only. The torque limit is 200% with an input of 10 V.
When the analog input is used as a frequency reference, switching between voltage (O) and current
(OI is performed) is performed as shown in the table below.
However, when none of the multi-function input terminals are set to 16 (AT: Analog input switching),
regardless of the A005 setting, the frequency reference value is the sum of the analog voltage input O
and analog current input OI values.
