1.4 Operation Overview
In communication with the Mitsubishi servo system controller, the inverter operation (speed control or
position control or torque control under vector control with encoder) or monitoring can be performed from a
program on the servo system controller.
Application of optical communication method greatly improved the communication speed and noise
resistance of the SSCNET ΙΙΙ as compared with the conventional SSCNET. In addition, 50m of the
maximum wiring length between stations is realized.

PRE-OPERATION INSTRUCTIONS
CAUTION
y Mounting both the FR-A7NS and FR-A7AP/FR-A7AL and performing vector control enables SSCNET ΙΙΙ
communication.
When operating the inverter with the FR-A7NS mounted and without FR-A7AP/FR-A7AL, option alarm
(E.OPT) occurs. (Refer to page 77.) Also option alarm (E.OPT) occurs when the FR-A7AP and FR-A7NS are not
connected with the FR-A7AP connection cable (the FR-A7AL and FR-A7NS are not connected with the FRA7NS connection cable) during a stop of the inverter. (Refer to page 77.) (In those conditions, however, option
fault (E.OPT) does not occur when Pr.800 Control method selection = "9" (vector control test operation) (refer to
page 49) or when Pr.499 SSCNET III operation selection = "9999" (operation invalid). (refer to page 42))
y An alarm such as overcurrent shut off (E.OC3) and position error large (E.OD) may occur depending on the
status of the motor current and droop pulses during inverter operation.
