• If the user configures the function codes wrong without completely understanding this Instruction
Manual and the FRENIC-Lift LM2A 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 LM2A series Reference Manual.
An accident or injuries could occur.
