WARNING
CAUTION
CAUTION
This Instruction Manual provides handling information and precautions for use of this product. Incorrect handling might cause an unexpected
fault. Before using this product, read all relevant instruction manuals carefully to ensure proper use.
Please forward this Instruction Manual to the end user.
Safety instructions
Do not attempt to install, operate, maintain or inspect this product until you have read this Instruction Manual and appended documents
carefully. Do not use this product until you have a full knowledge of this product mechanism, safety information and instructions. In this
Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".
Incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only
material damage.
Note that even the level may lead to a serious consequence depending on conditions. Be sure to follow the
instructions of both levels as they are critical to personnel safety.
Electric shock prevention
WARNING
Do not remove the front cover or the wiring cover of the inverter while the inverter power is ON. Do not operate the inverter with any cover or wiring cover removed,
as accidental contact with exposed high-voltage terminals and internal components may occur, resulting in an electrical shock.
Even if power is OFF, do not remove the front cover of the inverter except for wiring or periodic inspection as you may accidentally touch the charged circuits and
get an electric shock.
Before wiring or inspection, check that the display of the inverter operation panel is OFF. Any person who is involved in wiring or inspection shall wait for 10 minutes
or longer after power 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 wiring or inspection of this product shall be fully competent to do the work.
This product must be installed before wiring. Otherwise you may get an electric shock or be injured.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Doing so may cause an electric shock.
Do not touch this product or ha ndle the cables with wet hands. Doing so may cause an electric sh ock.
Injury prevention
CAUTION
The voltage applied to each terminal must be as specified in the Instruction Manual. Otherwise a burst, damage, etc. may occur.
The cables must be connected to the correct terminals. Otherwise a burst, damage, etc. may occur.
The polarity (+ and -) must be correct. Otherwise a burst, damage, etc. may occur.
While power is ON or for some time after power OFF, do not touch the inverter as it will be extremely hot. Doing so may cause a burn.

Additional instructions
The following instructions must be also followed. If this product is handled incorrectly, it may cause unexpected fault, an injury, or an electric
shock.
CAUTION
Transportation and installation
Do not stand or place heavy objects on this product.
The installing orientation of this product must be correct.

2INSTALLATION AND WIRING
2.1Pre-installation instructions
Check that the inverter's input power and the control circuit power are both OFF.
CAUTION
Do not install or remove this product while the inverter power is ON. Doing so may damage the inverter or this product.
To avoid damage due to static electricity, static electricity in your body must be discharged before you touch this product.
2.2Installation procedure
(1) Remove the inverter front cover. (Refer to Chapter 2 of the
Instruction Manual (Detailed) of the inverter for instructions
for removing the front cover.)
(2) Insert two spacers into the mounting holes that will not be
filled with mounting screws (see the diagrams on the next
page to identify the holes ).
(3) Fit the board mounted option connector on this product to
the guide of the option connector on the inverter, and insert
the option as far as it goes.
(4) Fasten this product to the inverter using the two mounting
screws through the holes on either side (tightening torque:
0.33 to 0.40 N·m). If the screw holes do not line up, the
connector may not be inserted deep enough. Check the
connector.

INSTALLATION AND WIRING
Page 11
NOTE
• When installing/removing the plug-in option, hold the sides of the option. Do not press on the parts on the option circuit
board. Stress applied to the parts by pressing, etc. may cause a failure.
• Be careful not to drop mounting screws during the installation or removal of the plug-in option.
• Only one option attached to the option connector with high priority can function at once if more than one option of the
same name are installed together on an inverter. Priority is given to option connectors in descending order (1 to 3),
and options having a lower priority do not function.
• When the inverter cannot recognize the option due to improper installation or any other reason, the protective function
(E.1 to E.3) is activated and the inverter cannot be operated. The indication shown (when a fault occurs) depends on
the connector used (option connector 1 to 3).

• When removing the plug-in option, remove the two screws on either side, and then pull it straight out. Pressure applied
to the option connectors and to the option board may break the option.

• For the open collector output, the signal may become unstable if the input resistance of the connected device is large
and the device may detect the signal incorrectly. In this case, adding a pull-up resistor, as shown below, will improve
the phenomenon.
• Select an appropriate pull-up resistor in consideration of the input current of the connected device so that the open
collector output current will not exceed the output permissible load current.

The encoder pulse divider option divides pulse signals input
from a motor encoder by the number set in Pr.413, and

This parameter is useful for the purpose, for example, of
decreasing the speed of response of a device which receives
the signals from the option.
