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

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

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.

1.3.4 Setting up the power supply for the EFC or pulse train generator
The external power supply should match the EFC power voltage or pulse train generator
voltage.
Otherwise, a failure might result.
When using an internal power supply
Connect the power supply wire to the terminal [PO] on the EFC interface card.
When using an external power supply
Connect the power supply wire to the terminal [PI] on the EFC interface card.

Chapter 3 PREPARATION FOR OPERATING
After completion of mounting/wiring but before turning the inverter's power ON, check the
followings.
(1) The wiring is correct.
(2) There is no cable waste or screws left.
(3) The screws and terminals are firmly tightened.
(4) The straggling wires at ferrules are not short-circuited to other terminals.
Furthermore, after powering the inverter ON but before starting inverter operation, check the
followings.
• Check the wiring surely before running the inverter. Incorrect wiring causes the inverter
or other devices to malfunction.
Failure to do so could cause failure or injuries.
• Be sure to mount the terminal cover before turning the power ON.
Do not remove any cover while the power is ON.
Doing so could cause electric shock.
• Confirm and adjust the setting of the function codes before running the inverter.
Otherwise, an accident could occur.

Chapter 4 EFC INTERFACE CARD FUNCTIONS
The combination of the EFC interface card and the EFC (open collector or complementary output)
makes feedback signals available, enabling the following controls.
4.1 Speed Control
This refers to speed control with EFC. (For details, refer to Chapter 6.)
4.2 Frequency Control with Pulse Rate Input
This control specifies a frequency command with pulse trains. (For details, refer to Chapter 5.)
It can be used together with speed control with EFC at the same time.
4.3 Positioning Control
This refers to simplified positioning control that detects the pulse count with feedback signals sent
from the EFC. (For details, refer to Chapter 7.)
This control can be used together with speed control with EFC and frequency control with pulse
rate input at the same time.

5-1
Chapter 5 FREQUENCY CONTROL WITH PULSE RATE INPUT
The pulse rate input feature supplies a frequencycommand to the inverter in pulse trains. Two pulse
input modes are available--B phase pulse (with signs) and forward/reverse rotation pulse trains.
The frequency control with pulse rate input can be enabled concurrently with the speed and posi-
tioning controls with EFC.

As shown in Figure 5.1, set the input pulse rate (kp/s) to the o07 data and set the reference fre-
quency (Hz) at the pulse rate (specified by o07) to the o08 data. The relationship between the input
pulse rate at A or B phase input and the reference frequency f* (or reference speed) can be calcu-
lated by the following expression.

5.5 Description of the Control
5.5.1 Input pulse command polarity
In the B phase pulse input system shown in Figure 5.2, the A phase voltage determines the polarity
of commands. In the run forward/reverse pulse input system shown in Figure 5.3, the presence of A
or B phase input determines the polarity of commands.
The combination of the command pulseinput and FWD/REV command determines the actual motor
rotational direction. Table 5.5 lists the relationship between the polarity of thepulse input, FWD/REV
command and motor rotational direction.
