Contact your local sales office for schedules and locations. ● A person who can access operating manuals for the protective devices (e.g. light curtain) connect- ed to the safety control system.
Page 6 Electric Shock Prevention WARNING: ● While power is on or when the inverter is running, do not open the front cover. Otherwise 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 or the charging part of the circuitry and get an electric shock.
Page 7 Fire Prevention CAUTION: ● Mount the inverter to incombustible material. Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.). Mount- ing it to or near combustible material can cause a fire. ●...
Page 8 Additional Instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc. Transportation and installation CAUTION: ● Any person who is opening a package using a sharp object, such as a knife and cutter, must wear gloves to prevent injuries caused by the edge of the sharp object. ●...
Page 9 Wiring CAUTION: ● Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi. These devices on the inverter output side may be overheated or burn out. ● The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V, W) is maintained.
Page 10 CAUTION: ● The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection. ● Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
Page 11 Emergency stop CAUTION: ● Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails. ● When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc.

Page 198: Control Method
Control method Parameters Control method V/F control (initial setting), Advanced magnetic flux vector control, and PM motor control are avail- able with this inverter. V/F control It controls the frequency and voltage so that the ratio of frequency (F) to voltage (V) is constant while changing the frequency.
Page 199 Parameters Control method PM motor control ● Highly efficient motor control and highly accurate motor speed control can be performed by using the inverter with a PM (permanent magnet embedded) motor, which is more efficient than an induction motor. ● The motor speed is calculated based on the output voltage and current from the inverter. It does not require a speed detector such as an encoder.

Control method Parameters 5.2.1 Changing the control method Set the control method. V/F control, Advanced magnetic flux vector control, and PM motor control are the control methods available for selection.

Page 703 Parameters (G) Control parameters What is regeneration avoidance operation? (Pr. 882, Pr. 883) ● When the regenerative status is large, DC bus voltage will rise, which may cause overvoltage alarm (E.OV[]). Regenerative status can be avoided by detecting this rise of bus voltage, and raising the frequency when the bus voltage level exceeds Pr.
Page 704 (G) Control parameters Parameters To detect the regenerative status during deceleration faster (Pr. 884) Since a rapid change in bus voltage cannot be handled by bus voltage level detection during the re- generation avoidance operation, deceleration is stopped by detecting the change in bus voltage and if it is equal or lower than Pr.

Page 765: Cleaning
Precautions for maintenance and inspection Inspection item 7.1.5 Cleaning Always run the inverter in a clean status. When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral detergent or ethanol. NOTES Do not use solvent, such as acetone, benzene, toluene and alcohol, as these will cause the inverter surface paint to peel off.
Page 766 Inspection item Precautions for maintenance and inspection Displaying the life of the inverter parts The inverter diagnoses the main circuit capacitor, control circuit capacitor, cooling fan, and inrush current limit circuit by itself and estimates their lives. The self-diagnostic warning is output when the life span of each part is near its end. It gives an indi- cation of replacement time.
Page 767 Precautions for maintenance and inspection Inspection item Replacement procedure of the cooling fan The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor is greatly affected by the surrounding air temperature. When unusual noise and/or vibration are noticed during inspection, the cooling fan must be replaced immediately.
