Chapter 1 BEFORE USING THE INVERTER
1.1 Acceptance Inspection
Unpack the package and check the following:
(1) The EFC interface card is the model you ordered.
(2) The EFC interface card is not damaged during transportation--no defective parts or lacking
parts.
(3) The model name "VXR-EFC" is printed on the EFC interface card. (See Figure 1.2.)
(4) The EFC interface card is applicable to your inverter.
Table 1.1 lists the inverter's ROM version to which the EFC interface card is applicable.
Table 1.1 Applicable ROM Version
Series Type of inverter Applicable motor rating ROM version
Jaguar VXR VXRE1- All capacities 0700 or later
Checking the ROM version
Use Menu #5 "Maintenance Information" on the keypad. (Refer to the Jaguar VXR Instruction
Manual, Chapter 3, Section 3.4.6 "Reading maintenance information."

1.2 Mounting the EFC Interface Card
• Turn the power OFF and wait for at least five minutes before starting installation.
Otherwise, electric shock could occur.
• Do not use the product that is damaged or lacking parts.
Doing so could cause a failure and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from
getting into the inverter.
Otherwise, a fire or an accident might result.
• Incorrect handling when mounting or removing the product could cause a failure.
A failure might result.
When handling the EFC interface card and interface printed circuit board (interface PCB), take any
antistatic measure or hold their hooks taking care not to directly touch their circuit boards;
otherwise, the static electricity charged in your body may damage them.
(1) Remove the terminal cover.
For details on how to remove the terminal cover, refer to the Jaguar VXR Instruction
Manual, Chapter 2, Section 2.3 "Wiring."
(2) If the interface PCB is installed on the inverter, push the hooks provided on both ends of the
interface PCB and pull it up and out of the inverter with both hands. (Store the removed
interface PCB for future use.)
(3) Connect the CN3 connector (shown in Figure 1.2) on the EFC interface card to the connector
on the inverter until it clicks into place.
(4) For inverters of 0.75 kW or below: Before reinstalling the terminal cover, cut off the barrier (see
Figure 1.3) of the terminal cover using nippers or the like
(5) Reinstall the terminal cover, taking care not to pinch control signal lines.
When reinstalling the terminal cover, refer to the Jaguar VXR Instruction Manual, Chapter 2,
Section 2.3 "Wiring."
For inverters of 3.7 kW or below: When performing the wiring for the main circuit
terminals, you need to remove the EFC interface card beforehand.

1.3 EFC Specifications and EFC Mounting Instructions
• Using the EFC whose specifications are not satisfied may cause the inverter and
equipment to malfunction.
Doing so could cause failure or injuries.
1.3.1 EFC specifications
Table 1.2 lists the applicable EFC specifications.
Table 1.2 Specifications of Applicable EFC and EFC Interface Card
Item Specifications
Applicable EFC
Encoder system Incremental system
Pulse resolution 20 to 3000 P/R
Input power requirements 5 VDC ±10% / 100 mA
(200 mA, when a single EFC is mounted.)
EFC power
supply Internal power supply +5 VDC ±10% / 200 mA
External power supply +5 VDC ±10%, 200 mA or more
Output signal Open collector (pull-up resistor: 620)
Complementary (totem-pole push-pull) voltage output
Note 1: The wiring length between the EFC and inverter should not exceed 20 m.
Note 2: When the EFC power is 200 mA or more, use an external power supply.
Note 3: The external power supply should satisfy the voltage specifications of the EFC.
1.3.2 Mounting the EFC to the motor
The counterclockwise rotation when viewed from the motor output shaft is regarded as "forward
rotation" (see Figure 1.4). During rotation in the forward direction, the EFC output pulse forms the
forward signal as shown in Figure 1.5 (B phase advances 90 degrees from A phase). During
rotation in the reverse direction, the EFC output pulse forms reverse signal (A phase advances 90
degrees from B phase).
Mount the EFC to the motor with a coupling, etc.
Table 1.3 lists the correct configurations of commands, rotational directions, and motor wiring. Any
other configuration fails to perform speed control normally.

You can monitor the digital input status of the EFC interface card with the inverter keypad. For
details, refer to the Jaguar VXR Instruction Manual, Chapter 3, Section 3.4.5 "Checking I/O signal
status."
1.3.3 Wiring between the EFC interface card and EFC
• Turn the inverter's power OFF and wait for at least five minutes before starting
connection.
• Qualified electricians should carry out wiring.
Otherwise, electric shock could occur.
• Noise may be emitted from the inverter, motor and wires. Implement appropriate
measure to prevent the nearby sensors and devices from malfunctioning due to such
noise.
Otherwise, an accident could occur.
Wire the EFC to the EFC interface card, observing the following precautions and referring to the
connection diagrams given in Figures 2.1 to 2.3.
(1) Turn the inverter's power OFF.
(2) Use a shielded wire for wiring between the EFC and the EFC interface card.
(3) To prevent malfunction due to noise, keep the wiring away from the main circuit wiring of the
inverter and the power wiring of other devices as far as possible (at least 10 cm). Do not route
them in the same duct.
(4) Complete the wiring for the EFC before turning the inverter's power ON.
(5) The wire size applicable to the option connection terminal on the inverter is AWG 18-24.
When using a wire with its end being stripped, strip its end by 5 to 7 mm. When using a ferrule,
use a vinyl-insulated ferrule.
Loosen the fixing screw, insert the wire end into the opening of the terminal block, and tighten
the screw.
