Can be used to suppress the magnetic noise from motor.
The magnetic noise will be approx. a few dB to 10dB(A) lower than the noise during operation
without reactor. (However, note that some magnetic noise occurs from the reactor.)
In a system in which 400 V class 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 AC reactor, surge voltage
suppression filter, sine wave filter and so on in the inverter's output side.
Note) Set the carrier frequency to 4.0~8.0kHz or larger when sine wave filter is used.
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.
The optional backup unit can be used with both 200V and 400V models.
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, 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)
More than one inverter can be controlled with a personal computer and so on if this unit is
used for connection between inverters and personal computer.
• Computer link: Since this unit makes it possible to connect inverters with higher-class
computer, FA computer, etc., a data communication network can be
constructed among multiple inverters.
• Communication among inverters: For the purpose of proportional operation of multiple
Unit type: USB001Z
For RS485/USB communication (between inverter and RS485/USB communication
conversion unit)
Cable type: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m)
A frequency meter, frequency setup device, RUN/STOP (forward, reverse) switch are built in
this operation panel. (Model: CBVR-7B1)
Applied control units of the AP series make various applied control possible if they are used in
combination with the inverter.
