Mitsubishi Electronics FR-V500 Emergency stop, Maintenance, inspection and parts replacement

CAUTION

!The electronic thermal relay does not guarantee protection of the motor from overheating.

!Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.

!Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equip- ment may be affected.

!Take measures to suppress harmonics. Otherwise power from the inverter may heat/damage the power capacitor and generator.

!When parameter clear or all clear is performed, each parameter returns to the factory setting. Re-set the required parameters before starting operation.

!The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the per- formances of the motor and machine.

!In addition to the inverter's holding function, install a holding device to ensure safety.

!Before running an inverter which had been stored for a long period, always perform inspection and test operation. In addition to the inverter's holding function, install a holding device to ensure safety.

5)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.

6)Maintenance, inspection and parts replacement

CAUTION

!Do not carry out a megger (insulation resistance) test on the control circuit of the inverter.

7) Disposing of the inverter

CAUTION

!Treat as industrial waste

8)General instructions

Many of the diagrams and drawings in this Instruction Manual (basic) show the inverter without a cover, or partially open. Never operate the inverter in this manner. Always replace the cover and follow this Instruc- tion Manual (basic) when operating the inverter.
