Sorts of separate-type options
No. Option name Function, purpose.
(1)
Input AC reactor
(PFL)
• Mandatory for VFAS1-6110KPC 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.
(2)
Radio noise
reduction filter
Zero-phase
reactor (Inductive
filter) (Ferrite core
type)
• 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.
(3)
Braking resistor
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 (200kW or larger): dynamic brake drive circuit is built in.
A resistor needs to be prepared separately.
(4)
Motor end surge voltage
suppression filter
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.

Control power supply
backup option
The VF-AS1 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.

LED Remote Keypad
option
(with parameter copy
function)
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: (common serial transmission waiting time) =
(default setting). Use communication cable No. 13 to connect to the inverter.
Panel type: RKP002Z
Cable type: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m)
(7)
LCD Remote Keypad
option
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)
