(1) Input AC reactor
(PFL)
• Mandatory for VFPS1-6110KPC and above.
• To be used for improvement of input power-factor of the inverter power source, for reducing
higher harmonic or suppressing external surge. The input reactor can be installed when the
AIC currents is more than 22kA.
• Effectual to prevent audio equipment used near the inverter from radio interference.
• Effectual to reduce noise in the input and output sides of the inverter.
• Excellent attenuation characteristic for several decibels in wide frequency band from AM
radio band nearly to 10 MHz.
To be used to shorten deceleration time for the reason of frequently operated quick
deceleration and suspension or high inertia load. This increases consumption of
regenerative energy in dynamic braking.
• Braking resistor: (resistor + protective thermal relay) are built in.
• Braking unit (250kW or larger): dynamic brake drive circuit is built in.
In a system in which general motor is driven by a voltage PWM type inverter using a
high-speed switching device (IGBT, etc.), surge voltage depending on cable constant may
cause deterioration in insulation of motor winding. Take measures against surge voltage such
as use of insulation-reinforced motor, installation of surge voltage suppression filter, sine
wave filter and so on in the inverter's output side.
The VF-PS1 supplies control power from the main circuit power supply in it. The optional
backup unit is designed to supply control power in the event the main circuit power supply
shuts down.
Extention operation panel unit with parameter copy function. Includes LED display,
RUN/STOP key, UP/DOWN key, MODE key, ENT key, EASY key, and COPY MODE key.
(When using this unit, set as follows:
(default setting). Use communication cable No. 13 to connect to the inverter.
Panel type: RKP002Z
Cable type: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m)
This LCD operation panel unit can be installed to the inverter unit. Includes LCD display,
RUN key, STOP/RESET key, job dial, ESC key, FWD/REV key and F1 to F4 key.
Special cable is needed to connect the inverter and LCD panel.
Panel type: RKP004Z
LCD cable type: CAB0071 (1m), CAB0073 (3m), CAB0075 (5m) , CAB00710 (10m)
