• If the user configures the function codes wrong without completely understanding this Instruction
Manual and the FRENIC-Lift LM2C series Reference Manual, the motor may rotate with a torque or at a
speed not permitted for the machine.
An accident or injuries could occur.
• Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input
terminals L1/R, L2/S and L3/T, voltage may be output to inverter output terminals U, V, and W.
• Even if the motor is stopped due to DC braking, voltage is output to inverter output terminals U, V, and
W.
An electric shock may occur.
• The inverter can easily accept high-speed operation. When changing the speed setting, carefully check
the specifications of motors or equipment beforehand.
Otherwise, injuries could occur.
• Do not touch the heat sink because it becomes very hot.
Doing so could cause burns.
• The DC brake function of the inverter does not provide any holding mechanism.
Injuries could occur.
• Ensure safety before modifying customizable logic related function code settings (U codes and related
function codes) or turning ON the "Cancel customizable logic" terminal command CLC. Depending
upon the settings, such modification or cancellation of the customizable logic may change the operation
sequence to cause a sudden motor start or an unexpected motor operation.
• If any abnormality is found in the inverter or motor, immediately stop it and perform troubleshooting,
referring to the FRENIC-Lift LM2C series Reference Manual.
An accident or injuries could occur.
・ This unit has more than one power supply(R0/T0 and 24Vdc)-Disconnect all supplies before servicing to
avoid electric shock.
An electric shock may occur.
