CAUTION
Instructions for safe and correct operation
1.
The capacity of the power source must be in the range 1.5 times the inverter capacity to 500
kVA. If the power source has 500 kVA or higher capacity and the length of the cable
between it and the inverter is 100 m or less, or if the power source has a phase advancing
capacitor selector, excessive peak current will flow into the power source input circuit and
may damage the converter. If this is the case, install power factor improvement AC reactor
at the input of each inverter.
2.
Do not connect the phase advancing capacitor to the inverter output. Otherwise, the
capacitor may be damaged.
3.
Do not install an electromagnetic contactor between the inverter and motor. Run/stop the
motor from inverter operation panel using the RUN switch or control input terminal. Do not
operate the electromagnetic contactor installed on the power source more often than
actually required.
In particular, never attempt to start or stop the motor with this electromagnetic contactor.
4.
Operating the motor through the inverter increases leakage current that may trip the leakage
breaker. If this is the case, use leakage breaker of high frequency proof type (designed for
use with inverter) on both the system causing the problem and system affected.
5.
The total cable length of the inverter and motor must be shorter than 30 m. To use a cable
longer than 30 m, provide a reactor between the inverter and the motor, or reduce the
inverter’s carrier frequency.

(14.9 kHz or less)
(10.1 kHz or less)
(3.9 kHz or less)
6.
To use the electronic thermal trip function incorporated in the inverter, observe the following
instructions.
• Check the rated current of your 3-phase induction motor to define the electric thermal
value.
• Use one motor for each inverter.
7.
To control several motors with an inverter (parallel operation), select the inverter’s capacity
so that the total of the motors’ rated currents does not exceed the inverter’s rated current.
Note that, if you select the inverter’s capacity based on the total of the motors’ capacity, the
inverter’s rated current may be exceeded depending on the motor type.

System Configuration and Wiring
Precautions when wiring
Internal circuits retain high voltage for a certain period time after power is off. Wait at least for
15 minutes after power off before starting any wiring.
Main circuit
(1) If the power supply terminals (R/L1, S/L2 and T/L3) and motor terminals (U/T1,
V/T2 and W/T3) are connected in reverse, the inverter will be damaged. Be
sure not to connect these terminals in reverse.
(2) Do not ground the main circuit terminal.
(3) Do not short-circuit the motor terminals (U/T1, V/T2 and W/T3).
(4) The ground (E) terminal is the inverter’s frame ground terminal.
(5) To connect the main circuit terminal, be sure to use a crimp terminal with
insulation sheath.
(6) To run the inverter, use the no-fuse breaker (NFB) according to the standard
connection diagram.
Select a no-fuse breaker according to the motor ratings.
(7) Be sure to remove the phase advancing capacitor from an existing motor.
Control circuit
(1) When connecting a control circuit conductor, strip off a suitable length of insulation: too
long bare conductor will touch with another conductor; too short bare conductor will
easily pull off the connection. When connecting two more conductors together, twist
them before wiring or connecting.
５.５㎜±１㎜
(2) When using a bar terminal or solid conductor, select one having a diameter equal to 0.9
mm or less. Fastening screw may be damaged.
(3) Do not apply more than 24 VDC, 50 mA to the output terminals (COM1, O1, O2), or
apply voltage to terminal in reverse.
Do not apply 30 VAC, 2 A (or 30 VDC, 2 A) to the output terminals (COM2, NO and NC).
(4) Do not apply an external voltage to the input terminals (I1 to I6).
(5) Do not short-circuit the frequency setting power supply terminal (5 V) and the external
power supply terminal (12 V) with the control ground (G) terminal.
(6) To directly drive the relay by the output terminals (COM1, O1, O2), mount a flywheel diode
(FD).
<Examples> Fuji Electric
COM1 01/02
ＦＤ（１００Ｖ １Ａ）
ERA15-01
ERB12-01
Pay attention to polarity of diode.
ＲＹ
(7) For connections to the control circuit, use twisted cables or shielded cables.
(8) The cable connected to the control circuit must be placed apart from a power cable.
(9) To tighten a cable, put a screwdriver on the terminal perpendicularly.

Operation Function
Operation function
The inverter has the following control functions that are made active from the operation
panel and terminal block.
Operation control
Description
Jogging
Acceleration/deceleration time is set to “0”. This function is optimum for
positioning. By setting [
Operation mode selection] to “2-speed mode”,
jogging operation is enabled.
When the “I3” and “G” control input terminals are short-circuited, CCW
jogging is enabled. When “I4” and “G” are short-circuited, CW jogging is
enabled, and the jogging frequency is output.
You can switch over between the normal operation mode and the jogging
mode.
The jogging frequency can be specified in the range of 0 to 30 Hz. If the
jogging frequency is too high, the inverter may trip due to overcurrent.
Free-run stop
Turns off the output voltage applied to the motor, allowing the motor to coast.
This function is useful to brake the motor mechanically. Remember that
touching the motor output terminals (U/T1, V/T2 and W/T3) may cause
electric shock even if the free-run stop function is activated.
DC brake
Activates the brake by applying a direct current to the motor at the time
when the inverter shifts from the running status to the stop status. If the
CCW, CW or jogging command is issued while the DC brake function is
activated, the DC brake is disabled, and the motor starts running as
specified by the command.
Positioning DC
brake
When a stop command is issued during normal operation, the motor
soft-stops, and the DC brake is activated when the output frequency is
reduced to 3 Hz. (The frequency at which the brake is activated can be
changed with the parameter).
When the frequency is set to “0”, the DC brake is activated when the output
frequency falls below 1 Hz.
The DC brake intensity (torque) and time can be specified with the
parameters.
DC brake for
full-range stop
When a stop command is issued during normal operation, the DC brake is
immediately activated without soft-stop.
The DC brake intensity (torque) and time can be specified with the
parameters.
The DC brake time is twice as long as the time specified for “Positioning DC
brake”.

■ Input terminal description
(1) Input terminals are given the following priority.
DC brake < Normal operation < Jogging < Free-run stop < External forced trip
Example)
① If the run command is issued while the DC brake is activated, the motor
will immediately start running.
② If the free-run stop command is issued during jogging operation, the
motor will coast to stop.
③ Even if the run command is issued while the free-run command is
activated, the motor will not start running.
(2) If both the CCW and CW commands are issued during trip, the trip can be
canceled. Before canceling the trip, remove the cause of the trip.

operation, the output frequency is
reduced for trip prevention.
(The operation level can be
adjusted with [

If the converter’s DC voltage
exceeds approx. 775 V during
deceleration, the deceleration time
is prolonged for trip prevention.
(The deceleration time can be
adjusted with [

When the converter’s DC voltage
falls below approx. 360 V, it is
judged as “instantaneous power
failure”, and the inverter’s output is
turned off.∗1 When the converter’s
DC voltage falls below approx.
300 V, the control circuit is reset.
If the voltage is restored by the

Maintenance/Inspection
You should perform maintenance/inspection on a regular basis in order to ensure safety
and keep the inverter in good running order.
Precautions when performing maintenance/inspections
(1) The power should be turned on/off only by the person performing the task.
(2) The internal circuits of the inverter remain charged with high voltage for a short
while after power is turned off. To perform inspection, first turn off the power and
then wait for the LED display on the operation panel to go off (min. 15 minutes).
(3) Do not use a megger for the purpose of measuring insulation resistance.
Otherwise, the inverter is damaged.

Conformity to EC Directive / UL Standard
EC Directive
The EC Directive is applied to all electronic products that provide proper functions and are exported to
EU (European Union) for direct sales for general consumers. These products must conform to the EU
uniformed safety standards, and the CE marking that indicates the conformity to the standards must be
affixed to the products.
Inverters are handled as the components to be incorporated in machinery or equipment, not the
above-mentioned product that provides proper functions and are exported for direct sales for general
consumers. Therefore, applying the CE marking to inverters is not compulsorily required.
To facilitate the conformity of the machinery or equipment that incorporates inverters to the EC Directive,
we attain conformity to the relevant standards of the Low Voltage Directive.
Conformity to the EMC Directive
Regarding our inverter systems, we define models (conditions) of their installation distance, wiring and
so on for inverters and general-purpose motors, so that the models conform to the relevant standards of
the EMC Directive.
However, when an inverter system is actually incorporated in machinery or
equipment, its wiring and grounding conditions may be different from the models. For this reason, the
machinery or equipment in which the inverter and general-purpose motor are incorporated must
undergo the final examination to verify the conformity to the EMC Directive (particularly, in terms of
unnecessary radiation noise and noise terminal voltage).

･ Be sure to ground the neutral terminal of the power supply.
･ Select a cable size conforming to EN60204-1.
Circuit breaker / Fuse
Be sure to connect a circuit breaker conforming to the IEC and UL standards, or a fuse conforming to
the UL standard between the power supply and the noise filter. ∗2
Noise filter
To provide a noise filter for the power supply with several inverters connected, consult the noise filter
manufacturer.
Surge absorber
Connect a surge absorber in the noise filter’s primary circuit.
Conformity to the UL Standard
When the above ∗1 and ∗2 installation conditions are satisfied, the inverter conforms to the UL508C
standard (File No. E164620).
<Note>
Before conducting a withstand voltage test for machinery or equipment, be sure to remove the surge
absorber. Otherwise, the surge absorber may be damaged.

Signal line noise filter
Connect signal line noise filters to all cables (power cable, motor cable, operation panel remote cable
and interface cable).
Grounding
(1) To prevent an electric shock, be sure to connect the inverter’s protective earth terminal (
) with
the control panel’s protective earth terminal (PE).
(2) Two protective earth terminals (
) are provided. Do not connect these terminals together.
