• Using the FR-A8TP together with the Vector control compatible plug-in option 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 / Vector control compatible plug-in option).

Encoder option selection
0 (initial value)
1
*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.
Parameter name
Encoder rotation direction
Number of encoder pulses
Encoder signal loss detection
enable/disable selection
*2 The number of pulses is fixed to 1024 for the FR-A8APR.
• 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.
NOTE
• Pr.862 setting is valid even when either the FR-A8TP or Vector control compatible plug-in option is installed. For using the
FR-A8TP alone, the motor does not run when Pr.862 is the initial value as it is. (When the RT signal is OFF)
