Three line operation control 2 (d 4): Controlling parameter 4-04, terminal MI1, MI2 and MI3, in which MI1
run (Triggering), MI2 run(Triggering), MI3 STOP(Normally closed). When 4-04 is set as 4, function set by
MI2 and MI3 is invalid. The wiring diagram is as follows.

Note: The corresponding function of MI2 and MI3 will be restored when 4-04 is not set as from 1 to 4.
External fault input (d5, d6 )
Description of action: once the AC motor driver receives EF signal, the output will be stopped
immediately and EF will be displayed on digital manipulator. At this moment, the motor rotates
normally. The operation can be continued through pressing RESET after disappearing of external
fault.
External RESET input (d7):
Description of action: Provided that faults such as EF, OH, OC or OV occur to the AC motor drive,
Terminal RST shall be applied after cause eliminated to reset the AC motor drive. The terminal is in
a same function with RESET key on the digital operator.
Multi-step speed reference input (d8, d9, d10 ): Available to set terminals MI1 (4-05), MI 2(4-06),
MI3 (4-07) and RST (4-08)
Description of action: 8 step speeds in total shall be commanded by this 3 terminal switches.
Relative parameters are (5-00 to 5-06) and main speed setting. Apart from relative parameters,
multi-step operation shall also be supported by operation reference. Auto-operation shall also be
available by this function cooperating with program running. For setting of this function, see 5-18 to
5-25 for detailed descriptions.
Function d11 is reserved.
Function sources switch (d12)
Description of action: when it is used to set the switching action of terminals. the frequency source
of inverter will be switched to 2-01 given (auxiliary frequency input source) from 2-02 given
(combination way of frequency sources) and return to 2-02 given when the switch is turned off.
Accel/decel inhibition reference input (d13)
Description of action: In performing Accel/decel inhibition function, Accel/decel of AC motor drive
shall be stopped immediately. When this function is cancelled, Accel/decel of AC motor drive shall
be continued from inhibition place. This reference shall only be available during acceleration or
deceleration of the AC motor drive.
Reference input of 1
st
and 2
nd
accel/decel switching (d14):
Description of action: Prior to closing of terminals switch, the accel/decel time of AC motor drive
shall be in accordance with setting of Parameter 1-09 and 1-10. During switch closing, accel/decel
time shall be in accordance with setting of Parameter 1-11and 1-12. If AC motor drive is in constant
speed, changing of switches shall not influence output frequency, which shall be effective when
acceleration or deceleration of motor drive is performing.
