 Parameter settings for the motor under Vector control
Using the control terminal option FR-A8TP together with the FR-A8AP enables Vector control or machine end orientation
control by switching between two encoder-equipped motors. Use Pr.862 to set the combination of the motors (first/second) and
the options (FR-A8TP/FR-A8AP).

*1 When Pr.450 Second applied motor = "9999", the first motor is selected even if the RT signal turns ON.
Use the following parameters for the encoder input setting. The encoder input setting can be made regardless of the Pr.862
setting and first/second motor setting.

NOTE
• To input the RT signal, set "3" in any of Pr.178 to Pr.182, Pr.185, or Pr.189 (Input terminal function selection) to assign the
function to a terminal.
• Pr.862 setting is valid even when either the plug-in option or control terminal option is installed. For using the control
terminal option alone, the motor does not run when Pr.862 is the initial value as it is. (When the RT signal is OFF)
