    Precautions for use When driving a 400V general-purpose motor with an inverter using extremely long wires, damage to the insulation of the Driving a 400 V motor may occur. Use an output circuit filter (OFL) if general-purpose necessary after checking with the motor manufacturer. Fuji motor motors do not require the use of output circuit filters because of their reinforced insulation.

In running Single-phase motors are not suitable for inverter-driven special variable speed operation. Use three-phase motors. motors Single-phase motors Even if a single-phase power supply is available, use a three-phase motor as the inverter provides three-phase output.

  • Page 17 When mounting two or more inverters Horizontal layout is recommended when two or more inverters are to be installed in the same unit or panel. If it is necessary to mount the inverters vertically, install a partition plate or the like between the inverters so that any heat radiating from an inverter will not affect the one/s above.
  • Page 18 (3) Mounting direction Mount the inverter vertically to the mounting surface and fix it securely with four screws or bolts so that the logo "FRENIC-Multi" can be seen from the front. Do not mount the inverter upside down or horizontally. Doing so will reduce the heat dissipation efficiency of the inverter and cause the overheat protection function to operate, so the inverter will not run.

  • Page 100 During a momentary power failure, the motor slows down. After pow er is restored, the inverter restarts at the frequency just before the momentary power failure. T hen, the current limiting function works and the output frequency of the inverter automatically decreases. When the output frequency matches the motor speed, the motor accelerates up to the original output frequency.
  • Page 101 Restart after momentary power failure (Frequency fall rate) (H14) During restart after a momentary power failure, if the inverter output frequency and the idling motor speed cannot be harmonized with each other, an overcurrent will flow, activating the overcurrent limiter. If it happens, the inverter reduces the output frequency to match the idling motor speed according to the reduction rate (Frequency fall rate: Hz/s) specified by H14.

If you set it at an extremely high value, control may become unstable and an overvoltage alarm may result in some cases. The DC brake function of the inverter does not provide any holding mechanism.

Use them in accordance with your system requirements. For details, refer to the FRENIC-Multi User's Manual (MEH457), Chapter 6 "SELECTING PERIPHERAL EQUIPMENT."...
  • Page 191 Name of peripheral Function and application equipment An MC can be used at both the power input (primary) and output (secondary) Magnetic sides of the inverter. At each side, the MC works as described below. When contactor (MC) inserted in the output circuit of the inverter, an MC can also switch the motor drive power supply between the inverter output and commercial power lines.
  • Page 192 Name of option Function and application A DCR is mainly used for power supply matching and for input power factor DC reactors correction (for reduction of harmonics). (DCRs) 1) For power supply matching - Use a DCR when the capacity of a power supply transformer exceeds 500 kVA and is 10 times or more than the rated inverter capacity.
