SAFETY INSTRUCTIONS
!While power is on or when the inverter is running, do not open the front cover. You may get an electric shock.
!Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage
terminals and charging part and get an electric shock.
!Even if power is off, do not remove the front cover except for wiring or periodic inspection. You may access the
charged inverter circuits and get an electric shock.
!Before starting wiring or inspection, check to make sure that the inverter power indicator lamp is off, wait for at
least 10 minutes after the power supply has been switched off, and check that there are no residual voltage using
a tester or the like..

PRE-OPERATION INSTRUCTIONS
1.5 Operation Overview
In communication with the Mitsubishi motion controller, the inverter operation (speed control or position
control or torque control under vector control with encoder), monitoring, or parameter setting can be
performed from a program on the motion controller.
SSCNET enables less wiring, improved reliability, improved synchronous control performance and motion
controller-driven multi-axis batch control.
CAUTION
The inverter can perform vector control with encoder (speed control, position control, torque
control) under the command from the motion controller. (Pr. 800 "control system selection" is
made invalid.)

Set the inverter station number before switching on the inverter and do not change the setting while power is on.
SSCNET allows up to eight axes to be connected in one communication system.

Normal start.
The inverter starts in the operation
mode set in Pr. 79 "operation mode
selection".
REMARKS
1. If any of the station No. 8 to No. E is set to the inverter, it is placed in a communication initialization waiting status after
power-on, but communication is not established. Do not use 8 to E.
2. When the station No. F is set to the inverter, it starts in the external operation mode (when Pr. 79 = 0) and operates
normally. It cannot perform SSCNET operation.
Refer to the inverter manual for Pr. 79 "operation mode selection" for the station No. F.
3. Set the station numbers consecutively in connection order. (You can also set the station numbers independently of the
connection order.)
CAUTION
1. If you change any station number while the inverter power is on, the setting is not made valid. The setting is
made valid after power is switched on again or the RES signal is turned on.
2. You cannot set the same station number to two or more inverters on the same bus. (Such setting disables
normal communication.)
3. Set the switch securely into the switch numeral position.
Setting it in a middle position disables normal data communication.

INSTALLATION
2.2.2 Setting the terminating resistor
The terminating resistor setting jumper connectors are factory-set in the terminating resistor absent
(OPEN) position. To make the terminating resistor present, change the positions of both jumper connectors
on the FR-V5NS to the 150Ωpositions. Only the terminating resistor of the inverter (servo amplifier)
furthest from the motion controller should be made present (150Ω).
CAUTION
1. Do not change the jumper connector positions while power is on.
2. Always fit the jumper connector to only one of either position. If they are fitted to both
positions simultaneously, the option unit may be damaged.
3. For the handling of the servo amplifier terminating resistor, refer to the instruction manual of
the servo amplifier.

INSTALLATION
2.3 Installation and Removal
(1) Install the option unit to Slot 3. (If you install it to Slot 1 or 2, E.OP1 (E.OP2) is displayed and operation is not performed.)
(2) Insert the option unit connector into the Slot 3 connector of the inverter securely. At this time, also insert the option
fixing holes securely.
Refer to the following diagram for the position of Slot 3. Push the option unit securely into the option fixing hook.
(3) Fix the two right and left places of the option unit to the inverter securely with the accessory mounting screws. If the
screw holes do not line-up, the connector may not have been inserted securely. Check for insecure insertion.
(4) To remove the option unit, remove the two left and
rightscrews, and then hold theoption unit and pull
its bottom toward you asshown in the figure. (The
option unit is fixed by the hook of the inverter.)
CAUTION
You cannot use this option with any other communication options. Also, there are restrictions on some of the other
option functions. (Refer to page 24.)

3.4 Wiring Route
•Route the SSCNET cables using the space on the right side of the control circuit terminal.
•Connect the earth (ground) cable to the earth (ground) terminal of the inverter using the space on the left
side of the control circuit terminal. (For the position of the earth (ground) terminal of the inverter, refer to
the inverter manual.)
When reinstalling the front cover of the inverter, route the cables in the wiring space securely
so that the inverter control circuit terminal and option connection cables are not caught
between the inverter and cover.

4. SSCNET COMMUNICATION STATUS
When the inverter is fitted with the SSCNET communication unit (FR-V5NS) and has any of station No. 0 to No. 7, pow-
ering it on places it in the SSCNET communication initialization waiting status. In this status, the inverter is put in the
SSCNET operation mode and cannot be switched to the external or PU operation mode. In addition, the Pr. 79 "opera-
tion mode selection" setting is disabled. How SSCNET communication is performed is shown below.
The status of communication with the motion controller can be monitored as a communication status.
To monitor it, set "39" (communication status) in Pr. 52 "DU/PU main display data selection". (Refer to page 16.)
*1. The inverter is put in the SSCNET operation mode.
*2. In the part #, the axis number appears.
("21" appears when the station number is 0.)
*3. To reset the alarm, the alarm reset signal from the SSC-
NET or the RES terminal is valid.
A power-on reset recovers the inverter from the alarm in
the initialization waiting status.
*4. When communication is interrupted, an inverter reset (CF
alarm) or inverter alarm (E.OP3) occurs.
To select alarm output presence/absence and stop opera-
tion, use Pr. 499 "action selection at SSCNET communica-
tion interruption". (Refer to page 16.)
*5. If the motion controller is powered off during inverter power
input, the inverter is placed in the initialization waiting sta-
tus.
