Thank you for choosing this Mitsubishi Inverter plug-in option.
This instruction manual gives handling information and precautions for use of this equipment. Incorrect handling might cause an unexpected fault. Before using the equipment, please read this manual carefully to use the equipment to its optimum.
Please forward this manual to the end user.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect this product until you have read through this instruction manual and appended documents carefully and can use the equipment correctly. Do not use this product until you have a full knowledge of the equipment, safety information and instructions.
In this instruction manual, the safety instruction levels are classified into "WARNING" and "CAUTION".
WARNING
CAUTION
Assumes that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Assumes that incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause physical damage only.
Note that even the
CAUTION
level may lead to a serious consequence according to conditions. Please follow the instructions of both levels because they are important to personnel safety.
SAFETY INSTRUCTIONS
1. Electric Shock Prevention
WARNING
• 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 or wiring cover
removed. Otherwise, you may access the exposed highvoltage terminals and charging part and get an electric shock.
• 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
Indication of the inverter operation panel 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. The capacitor is charged with high voltage for some time after power off and it is dangerous.
• Any person who is involved in the wiring or inspection of this
equipment should be fully competent to do the work.
• Always install the plug-in option before wiring. Otherwise,
you may get an electric shock or be injured.
• Do not touch the plug-in option with wet hands. Otherwise
you may get an electric shock.
• Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise you may get an electric shock.

2. Injury Prevention
CAUTION
• Apply only the voltage specified in the instruction manual to
each terminal. Otherwise, burst, damage, etc. may occur.
• Ensure that the cables are connected to the correct terminals.
Otherwise, burst, damage, etc. may occur.
• Always make sure that polarity is correct to prevent damage, etc.
Otherwise, burst, damage may occur.
• While power is on or for some time after power-off, do not touch
the inverter as it is hot and you may get burnt.
3. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
1) Transportation and mounting
CAUTION
• Do not install or operate the plug-in option if it is damaged or
has parts missing.
• Do not stand or rest heavy objects on the product.
• Check that the mounting orientation is correct.
• Prevent other conductive bodies such as screws and metal
fragments or other flammable substance such as oil from entering the inverter.
2) Trial run
CAUTION
• Before starting operation, confirm and adjust the parameters.
A failure to do so may cause some machines to make unexpected motions.
3) Usage
WARNING
• Do not modify the equipment.
• Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the inverter.
CAUTION
• When parameter clear or all parameter clear is performed,
reset the required parameters before starting operations.
Each parameter returns to the initial value.
• For prevention of damage due to static electricity, touch
nearby metal before touching this product to eliminate static electricity from your body.
4) Maintenance, inspection and parts replacement
CAUTION
• Do not test the equipment with a megger (measure insulation
resistance).
5) Disposal
• Treat as industrial waste.
CAUTION
6) General instruction
All illustrations given in this manual may have been drawn with covers or safety guards removed to provide in-depth description. Before starting operation of the product, always return the covers and guards into original positions as specified and operate the equipment in accordance with the manual.

2.3 Wiring
(1) Strip off the sheath of the cable to wire.
Strip off the sheath about the size below. If the length of the sheath pealed is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off.
Cable stripping size
Wire the stripped cable after twisting it to prevent it from becoming loose.
In addition, do not solder it.
Use a bar type terminal as required.

Description
The set frequency data entered from the digital signal input terminals (X0 to X15) is always imported independently of whether the DY signal is on or off.
The set frequency data entered from the digital signal input terminals (X0 to X15) is imported only when the DY signal is on.
The set frequency data is not imported when the DY signal is off.
Therefore, even if the input status of the X0-X15 signal changes, the set frequency data before off of the DY signal is valid.
The set frequency data entered from the digital signal input terminals (X0 to X15) is always imported independently of whether the DY signal is on or off.

z Input method of torque command
Torque command may be input in either of the following two ways:

(2) Method to directly input the torque command value as numeral value in digital
When "9999" is set in Pr.448, the input signal is considered as a torque command value.
Even if a value higher than 190H (400) is input, the torque command value is clamped at 400%.

4.3 Instructions
(1) Acceleration/deceleration time
When the frequency is set with the digital input signal, the acceleration/deceleration time is the period of time required to reach the Acceleration/deceleration reference frequency set in Pr. 20. This is the same as when using the analog signal input.
(2) There are the following restrictions on the digital input signal:
When the signal is used to enter a BCD code, 0A
H
to 0F
H
entries are ignored during operation and the previous inputs are used to continue operation.
If binary input is changed to BCD code input with 0A
H
to 0F
H
input, the set frequency becomes 0Hz.
(3) If 0 to 5V (0 to 10V) is input at the inverter terminal 1 from the external volume with the FR-A7AX fitted, the inverter operates at the frequency obtained by adding the FR-A7AX BCD code input and the compensation input from terminal 1 only when
"
2, 3, 12 or 13
"
is set in Pr. 304.
When switching the inputs e.g. between volume input to perform manual operation and BCD code input to perform automatic operation, set the BCD code input to "0" under manual operation.
(4) The priorities of the frequency setting are as follows.
JOG>Multi-speed operation (RH, RM, RL) >PID (X14) >AU (terminal 4) >Digital command by the FR-
A7AX > terminal 2
"
(When digital input is valid, terminal 2 is invalid.)
