Before using this product, always read this Instruction Manual carefully to use this product correctly. Please forward this Instruction Manual to the end user.

Safety instructions

Do not attempt to install, operate, maintain or inspect the 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".

The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed

because these are important to personal safety.

 Electric Shock Prevention

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.

Warning

 While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover removed. Otherwise

you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock.

 Do not remove the inverter front cover even if the power supply is disconnected. The only exception for this would be when performing wiring and periodic

inspection. You may accidentally touch the charged inverter circuits and get an electric shock.

 Before wiring or inspection, LED indication of the inverter unit operation panel must be switched OFF. Any person who is involved in wiring or inspection shall wait

for at least 10 minutes after the power supply has been switched OFF and check that there is no residual voltage using a tester or the like. For some time after the power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous.

 Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.  The plug-in option must be installed before wiring. Otherwise you may get an electric shock or be injured.  Do not touch the plug-in optio n or handle the cables 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.

 Injury Prevention

Caution

 The voltage applied to each terminal must be the ones 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 or damage may occur.  While power is ON or for some time after power OFF, do not touch the inverter as it will be extremely hot. Touching these devices may cause a burn.

 Additional Instructions The following instructions must be also followed. If the product is handled incorrectly, it may cause unexpected fault, an injury, or an electric shock.

Caution

Transportation and mounting

 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.  The mounting orientation must be correct.  Foreign conductive objects must be prevented from entering the inverter. That includes screws and metal fragments or other flammable substance such as oil.  If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi product, the product will be damaged. Halogen-based materials are

often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated into Mitsubishi products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden package should also be performed be fore packaging the product.

Trial run

 Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.

Warning

Usage

 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 product.

Caution

Usage

 When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations. Because all parameters return to

their initial values.

 Static electricity in your body must be discharged before you touch the product.

Maintenance, inspection and parts replacement

 Do not carry out a megger (insulation resistance) test.

Disposal

 The inverter must be treated as industrial waste.

 Many of the diagrams and drawings in this Instruction Manual show the inverter without a cover or partially open for explanation. Never operate the inverter in this

manner. The cover must be reinstalled and the instructions in the Instruction Manual must be followed when operating the inverter.

4.3 Operation mode setting

4.3.1 Operation mode switching and communication startup mode (Pr.79, Pr.340)

 Operation mode switching conditions

Operation mode switching conditions

• The inverter is at a stop;

• Both the STF and STR signals are off; and

• The Pr.79 Operation mode selection setting is correct. (Set with the operation panel of the inverter.)

 Operation mode selection at power ON and at restoration from instantaneous power failure

The operation mode at power ON and at restoration from instantaneous power failure can be selected. Set a value other than "0" in Pr.340 Communication startup mode selection to select the network operation mode. After started in network operation mode, parameter write from the network is enabled.

NOTE

• Change of the Pr.340 setting is valid when powering on or resetting the inverter.

• Pr.340 can be changed with the operation panel independently of the operation mode.

• When setting a value other than 0 in Pr.340, make sure that the initial settings of the inverter are correct.

• When the inverter has received a communication establishment request from the master in the External operation mode or switchover mode, the operation mode is switched to the NET operation mode. However, after the error reset, the inverter enters the External operation mode and no communication establishment request may be sent from the master. Thus, setting Pr.340  "0" in advance is recommended.

• Refer to the Instruction Manual (Detailed) of the inverter for details of Pr.79, Pr.340.

 Operation mode can not be directly changed between the PU operation mode and Network operation mode.  The Pr.340 settings "2, 12" are mainly used for communication operation using the inverter RS-485 terminal.

When a value other than "9999" (selection of automatic restart after instantaneous power failure) is set in Pr.57 Restart coasting time, the inverter will resume the same operation state which was in before after power has been restored from an instantaneous power failure. When Pr.340 = "1, 10", a start command turns off if power failure has occurred and then restored during a start command is on.

 Switching between the PU and NET operation modes is available with the key on the operation panel or the X65 signal.  Refer to pa ge 77 for a switching method from the network.
