  • Page 24: Grounding Capacitor Switching Method

    E6581386 1.3.3 Grounding capacitor switching method The inverter is grounded through a capacitor. The leakage current from the inverter can be reduced using the selector switch, switching bar or switching screw (depending on the model) on the main circuit terminal board. This switching device is used to detach the capacitor from the grounding circuit or to reduce its capacitance.

  • Page 28: Notes On The Application

    Comparisons with commercial power operation The VF-PS1 Inverter employs the sinusoidal PWM system to supply the motor. This is why compared to operation with a commercial power there will be a slight increase in motor temperature, noise and vibration. The main supply voltage and current will also be distorted due to harmonic distortion while increase the line current.

  • Page 29

    E6581386 Method of lubricating load mechanisms Operating an oil-lubricated reduction gear and gear motor in the low-speed areas will worsen the lubricating effect. Check with the manufacturer to find out about operable speed range. Low loads and low inertia loads The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of 50% or under of the rated load, or when the load's moment of inertia is extremely small.

  • Page 30

    E6581386 In circuit configuration 1, the brake is turned on and off through MC2 and MC3. If the circuit is configured in some other way, the overcurrent trip may be activated because of the locked rotor current when the brake goes into operation.

  • Page 31: What To Do About The Leak Current

    E6581386 There is no fuse in the inverter's main circuit. Thus, as the diagram above shows, when more than one inverter is used on the same power line, you must select interrupting characteristics so that only the MCCB2 will trip and the MCCB1 will not trip when a short occurs in the inverter (INV1).

  • Page 32

    E6581386 (2) Affects of leakage current across supply lines Thermal relay inverter Power supply Leakage current path across wires (1) Thermal relays The high frequency component of current leaking into electrostatic capacity between inverter output wires will increase the effective current values and make externally connected thermal relays operate improperly. If the motor cables are more than 50m long, external thermal relay may operate improperly with models having motors of low rated current, especially the 400V class low capacity (3.7kW or less) models, because the leakage current will be high in proportion to the motor rating.

    E6581386 1.4.4 Installation Installation environment The VF-PS1 Inverter is an electronic control instrument. Take full consideration to installing it in the proper operating environment. Danger • Do not place any inflammable substances near the VF-PS1 Inverter. If an accident occurs in which flames are emitted, this could lead to fire.

  • Page 34

    Please consult with your supplier about these measures. • If the VF-PS1 Inverter is installed near any of the equipment listed below, provide measures to insure against errors in operation. Solenoids: Attach surge suppressor on coil. Brakes: Attach surge suppressor on coil.

    E6581386 Panel designing taking into consideration the effects of noise The inverter generates high frequency noise. When designing the control panel setup, consideration must be given to that noise. Examples of measures are given below. • Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the same conduit, do not run them parallel, and do not bundle them.

    E6581386 Sink logic/source logic (When inverter's internal power supply is used) Current flowing out turns control input terminals on. These are called sink logic terminals. The method generally used in Europe is source logic in which current flowing into the input terminal turns it on. Sink logic terminals and source logic terminals are sometimes referred to as negative logic terminals and positive logic terminals, respectively.

  • Page 225: Compliance With Safety Standards

    E6581386 Compliance with safety standards The VFPS1 inverter has the “power removal” safety function that complies with safety standards. To ensure safety performance, however, the mechanical system with which the VFPS1 inverter is used has to adhere to such standards as a whole. To be more specific, in order for the system to satisfy the following safety standards, it needs to be configured, as shown on the next page, with the power removal terminal of the VFPS1 inverter (PWR terminal on the control terminal board) so that it will coast or decelerate to a stop in the event of a failure.
