Analog I/O Settings
This section describes the analog I/O signal settings for this inverter.
8-3-1
Analog Input (Function Selection)
This inverter has an analog input terminal [AI1] with voltage input.
Analog input terminal [AI1] 0 to 10V, -10 to 10V
• For details on analog input adjustment, refer to 8-3-2 Analog Input Adjustment Function on page

*1. When using PID process command 1, torque bias, torque reference value and torque current command val-
ue with analog input terminals, configure parameters for selecting commands of each function in addition to
Input Terminal [AI1] Function Selection (3005Hex-3EHex). When both are set to analog input, analog input
signal is treated as a command.
Analog Input Extended Function Selection (3005Hex-3EHex)
By setting Input Terminal [AI1] Function Selection (3005Hex-3EHex), the following functions can be al-
located to each of the analog input terminals.

Auxiliary frequency setting
1
An auxiliary frequency input added to 1st Frequency Reference
Selection (3004Hex-02Hex). Not added to other than the 1st fre-
quency reference (such as the 2nd frequency reference, multi-
step frequency reference, etc.).
