Do not leave wire fragments inside the inverter. Wire fragments can cause faults, breakdowns, and
malfunctions.
WARNING
10
Chapter 1 - Installation
For input and output, use wires with sufficient size to ensure voltage drop of less than 2%.
Motor torque may drop if operating at low frequencies and a long wire run between inverter and
motor.
When more than one motor is connected to one inverter, total wiring length should be less than 500m
(1,640ft). Do not use a 3-wire cable for long distances. Due to increased leakage capacitance
between wires, over-current protective feature may operate or equipment connected to the output
side may malfunction.
Connect only recommended braking resistor between the B1 and B2 terminals. Never short B1 and
B2 terminals. Shorting terminals may cause internal damage to inverter.
The main circuit of the inverter contains high frequency noise, and can hinder communication
equipment near the inverter. To reduce noise, install RFI filters or line noise filters on the input side of
the inverter.
Do not use power factor capacitor, surge suppressors, or RFI filters on the output side of the inverter.
Doing so may damage these components.
Always insure the LED and charge lamp for the power terminal are OFF before wiring terminals. The
charge capacitor may hold high-voltage even after the power is disconnected. Use caution to prevent
the possibility of personal injury.
Grounding
The inverter is a high switching device, and leakage current may flow. Ground the inverter to avoid
electrical shock. Use caution to prevent the possibility of personal injury.
Connect only to the dedicated ground terminal on the inverter. Do not use the enclosure or a chassis
screw for grounding.
The protective earth conductor must be the first one in being connected and the last one in being
disconnected.
As a minimum, grounding wire should meet the specifications listed below. Grounding wire should be
as short as possible and should be connected to the ground point as near as possible to the inverter.

output.
I/O-01 to I/O-10: Scaling the analog input signals (V1 and I)
for frequency reference.
DRV-01: Acceleration Time
DRV-02: Deceleration Time
The inverter targets the FU2-70 [Ref. Freq. for
Accel/Decel] when accelerating or decelerating.
When the FU2-70 is set to “Maximum Frequency”,
the acceleration time is the time taken by the
motor to reach FU1-20 [Maximum Frequency]
from 0 Hz. The deceleration time is the time taken
by the motor to reach 0 Hz from FU1-20.
When the FU2-70 is set to ‘Delta Frequency’, the
acceleration and deceleration time is the taken to
reach a targeted frequency (instead the maximum
frequency) from a frequency.
The acceleration and deceleration time can be
changed to a preset transient time via multifunction inputs. By setting the multi-function inputs
(P1, P2, P3) to ‘XCEL-L’, ‘XCEL-M’, ‘XCEL-H’
respectively, the Accel and Decel time set in I/O25 to I/O-38 are applied according to the binary

This is a general pattern for constant
0
torque applications.
This pattern allows the motor to
accelerate and decelerate smoothly.
The actual acceleration and
deceleration time takes longer- about
40% than the time set in DRV-01 and
DRV-02.
This setting prevents shock during
acceleration and deceleration, and
prevents objects from swinging on
conveyors or other moving equipment.
This pattern provides more efficient
control of acceleration and deceleration
2
in typical winding machine applications.
The inverter makes shorten the
acceleration time by accelerating with a
current rate of about 150% of its rated
current and reduces the deceleration
time by decelerating with a DC voltage
rate of 95% of its over-voltage trip level.
Appropriate application: When the
3
maximum capability of the inverter and
the motor are required.
Inappropriate application: The current
limit function may operate for a long
period of time for loads that have high
inertia such as fans.
The inverter accelerates with a current
rate of about 120% of its rated current
4
and decelerates with a DC voltage rate
of 93% of its over-voltage trip level.
Description
☞
Note: In case of selecting the ‘Minimum’ or ‘Optimum’, the
DRV-01 [Accel Time] and DRV-02 [Decel Time] is ignored.
☞Note: ‘Minimum’ and ‘Optimum’ functions operate normally

These functions are to protect the motor from
overheating without using additional thermal
overload relay. Inverter calculates the
temperature rise of the motor using several
parameters and determines whether or not the
motor is overheating. Inverter will turn off its
output and display a trip message when the
electronic thermal feature is activated.
This function activates the ETH parameters by

This is used to display the motor speed. If you set
this value to 2, inverter will display 3600 rpm
instead 1800rpm at 60Hz output frequency. (See
motor nameplate)
This is used in ‘Slip Compensation’ control. If you
set this value incorrectly, motor may stall during

This is very importance parameter that must be
set correctly. This value is referenced in many
other inverter parameters. (See motor nameplate)
This parameter is only displayed when ‘Slip
Compen’ is selected in FU2-40 [Control Method].
This function is used to maintain constant motor
speed. To keep the motor speed constant, the
output frequency varies within the limit of slip
frequency set in FU2-32 according to the load
current. For example, when the motor speed
decreases below the reference speed (frequency)
due to a heavy load, the inverter increases the
output frequency higher than the reference
frequency to increase the motor speed. The
inverter increases or decreases the output by
delta frequency shown below.

Set the proportional gain for PID control. When PGain is set at 100% and I-Gain at 0.0 second, it
means the PID controller output is 100% for 100%
error value.
Set the integral gain for PID control. This is the
time the PID controller takes to output 100% for
100% error value.
Set the differential gain for PID control.
This is the frequency at which the output
frequency is limited during PID control.
[P Control] This is to compensate the error of a
system proportionally. This is used to make the
controller response fast for an error. When P
control is used alone, the system is easily affected
by an external disturbance during steady state.
[I Control] This is to compensate the error of a
system integrally. This is used to compensate the
steady state error by accumulating them. Using
this control alone makes the system unstable.
[PI control] This control is stable in many
systems. If “D control” is added, it becomes the 3
rd
order system. In some systems this may lead to
system instability.
[D Control] Since the D control uses the variation
ratio of error, it has the merit of controlling the
error before the error is too large. The D control
requires a large control quantity at start, but has
the tendency of increasing the stability of the
system. This control does not affect the steady
state error directly, but increases the system gain
because it has an attenuation effect on the
system. As a result, the differential control
component has an effect on decreasing the
steady state error. Since the D control operates
on the error signal, it cannot be used alone.
Always use it with the P control or PI control.

Description
The inverter turns off its output when the output current of the inverter flows more than
200% of the inverter rated current.
The inverter turns off its output if the DC voltage of the main circuit increases higher than
the rated value when the motor decelerates or when regenerative energy flows back to the
inverter due to a regenerative load. This fault can also occur due to a surge voltage
generated at the power supply system.
The inverter turns off its output if the output current of the inverter flows at 180%
inverter rated current for more than the current limit time (S/W).
The inverter turns off its output if the heat sink over heats due to a damaged cooling fan or
an alien substance in the cooling fan by detecting the temperature of the heat sink.
The internal electronic thermal of the inverter determines the over heating of the motor. If
the motor is overloaded the inverter turns off the output. The inverter cannot protect the
motor when driving a multi-pole motor or when driving multiple motors, so consider
thermal relays or other thermal protective devices for each motor.
Overload capacity: 150% for 1 min
The inverter turns off its output if the DC voltage is below the detection level. Insufficient
torque or over heating of the motor can occurs when the input voltage of the inverter
drops.
The inverter turns off the output when one or more of the input(R, S, T) phase is open and
the output load is over 50% of the inverter rated current for more than 1 minute. The
inverter checks whether the phase is open by detecting the DC voltage of the main circuit.
The inverter turns off its output when the one or more of the output (U, V, W) phase is
open. The inverter detects the output current to check the phase open of the output.
Used for the emergency stop of the inverter. The inverter instantly turns off the output
when the BX terminal is turned ON, and returns to regular operation when the BX terminal
is turned OFF. Take caution when using this function.
The inverter turns off its output when the output current of the inverter flows more than the
rated level (150% for 1 minute-Inversely proportional to time).
Use this function if the user needs to turn off the output by an external fault signal.
(Normal Open Contact)
Use this function if the user needs to turn off the output by an external fault signal.
