9999 No function
*1 When Pr. 59 Remote function selection = "1 or 2", the functions of the RL, RM and RH signals change as listed above.
*2 When Pr. 270 Stop-on contact/load torque high-speed frequency control selection = "1 or 3", the functions of the RL and RM signals change as listed above.
*3 The OH signal turns on when the relay contact "opens".
*4 The FR-A7AX (16-bit digital input) is needed to externally input a stop position under orientation control.
*5 Servo ON is made valid during position control under vector control operation.
*6 Available only when used with the FR-A7AP (option).
