Position control operation

4.3 Position control operation

On this inverter, you can use parameter and pulse inputs to exercise position control.

Refer to the Instruction Manual (detailed) for details.

4.3.1Position command from parameter setting

Position control is exercised using the position feed amounts set in Pr. 465 to Pr. 494.

4.3.2Position command from PLC

Position control is exercised by connecting the PLC, such as the MELSEC-Q series PLC positioning module (QD75), and the positioning control option (FR-V5AP) to the inverter.
