Alert Statements in this Manual
Caution
Be sure to use the specified Braking Resistor or Braking Resistor Unit.
Not doing so may occasionally result in moderate burns due to heating of the
Braking Resistor or Braking Resistor Unit.
When using a Braking Resistor or Braking Resistor Unit, be sure to install a
thermal relay to monitor the resistor temperature.
Include a sequence to turn OFF the power supply to the Inverter if the Braking
Resistor or Braking Resistor Unit overheats.
Terminals B1 and B2 are for connecting an optional Braking Resistor or Braking
Resistor Unit. Do not connect any device other than a Braking Resistor or Braking Resistor Unit to these terminals.
Doing so may occasionally result in moderate fire, heating, or equipment damage.
Do not open terminal covers while the power is being supplied or for at least
one minute after the power has been turned OFF.
Doing so may occasionally result in minor injury from electrical shock.
Do not remove the fan cover except when replacing the fan. Before replacing
the fan, first turn OFF the power and disconnect the wiring.
Doing so may occasionally result in minor injury from electrical shock.
Install external breakers (MCCB) suitable for the Inverter capacity on the power
supply side of the Inverter and take other safety measures against short-circuiting in load wiring.
Not doing so may occasionally result in property damage from short-circuiting
in load wiring.
Cover the Inverter or take other measures to prevent filings or lead clippings
from entering the Inverter during installation and wiring.
The Inverter contains high-voltage components and Inverter damage or property damage may occasionally occur if the high-voltage components are shortcircuited.
IX
■ Installation and Storage Environment
• Do not store, install, or operate the product in any of the following locations.
• Locations subject to direct sunlight.
• Locations subject to temperatures outside the range specified in the specifications.
• Locations subject to humidity outside the range specified in the specifications.
• Locations subject to condensation resulting from severe changes in temperature.
• Locations subject to corrosive or flammable gases.
• Locations subject to exposure to combustibles.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
■
Transporting, Installation, and Wiring
• Always use the original shipping box when transporting the Inverter.
• Do not apply excessive shock to the Inverter or drop the Inverter. The Inverter may malfunction
or may be damaged.
• Do not connect an AC power supply voltage to the U, V, and W output terminals. Doing so will
damage the Inverter.
• Do not connect any load other than a three-phase inductive motor to the U, V, and W output
terminals.
• Do not connect an AC power supply voltage to the control I/O terminals. Doing so will damage
the Inverter.
• Use 600-V polyvinyl chloride (PVC) cable with a wire size of 0.75 to 2 mm
2
to wire the main
circuit terminals. Also, tighten the terminal screws on the terminal block to a torque of 0.8 to
1.0 N·m.
• Take appropriate and sufficient shielding countermeasures when installing systems in the following locations. Not doing so may result in malfunction or equipment damage.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields and magnetic fields.
• Locations close to power lines.
■
Operation and Maintenance
• This Inverter can be set to operate from low speed to high speed. Operate the Inverter only
after sufficiently confirming the allowable range for the motor installation being used.
• Take measures to assure safety before performing maintenance or inspection, or replacing
components.
Precautions for Safe Use
X
■ Installation
• Mount the product vertically on a wall or on a DIN Track. Leave the prescribed space between
this product and the control panel surface and other devices.
■ Main Circuit Power Supply
• Use a three-phase, 200 to 230 V, 50/60 Hz power supply.
■ Operation after Power Interruptions
• If continuing operation is selected for the momentary power interruption restart selection parameter (P09), the system may unexpectedly start operation after a momentary power interruption is reset. Exercise suitable caution.
■ Operation Command Selection
• If the operation command selection parameter (P10) is set to “PLC” to enable using the control
circuit terminal inputs (STF and STR), the motor may start operation when the power supply
is turned ON or an alarm is reset if the control circuit terminals are left ON. Exercise suitable
caution. Also, if signals are checked during operation and a voltage is incorrectly applied to the
control circuit terminals, the motor may start moving unexpectedly. Always check safety before
performing signal checks.
■ Motor Overheating Protection (Electronic Thermal)
• The Inverter uses an electronic thermal to protect the motor from overheating. Set the rated
current of the motor in the rated motor current parameter (P01). If more than one motor is operated with one Inverter, set the rated motor current parameter (P01) to 0.0 to disable motor
overload detection, and install a thermal relay between the Inverter and each motor. Set the
thermal relay to the nameplate current at 50 Hz and to 1.1 times the nameplate current at 60
Hz.
■ Disposing of the Inverter
• Observe all applicable legal requirements when disposing of the Inverter.
