CAUTION
The input power supply voltage must match the rated voltage
specifications. Mismatch can cause a fire or accidents.
The terminal layout and terminal symbols must be checked to ensure that
connections are correct. Wrong connections can cause a fire or accidents.
Do not connect a power supply to the motor connection terminals U, V, W.
Doing so can cause a fire or accidents.
The motor connection terminals U, V, W must match the motor phase
sequence. Wrong connections can cause accidents due to reverse
rotation of the motor.
Do not connect a resistor across the DC terminals P/+-N/-. Doing so can
cause a fire or accidents.
Take measures to prevent peripheral sensors and equipment from
malfunctioning due to electromagnetic noises. Not doing so can cause
accidents.
Measures must be taken to prevent peripheral power capacitors and
generators from overheating or being damaged due to power harmonics.
Not doing so can cause a fire.
The power factor correction capacitor, surge suppressor, and radio noise
filter (FR-BIF option) must be connected on the power supply side.
Connection on the output side can cause a fire.
5. Operation
WARNING
The front cover must be reinstalled before switching input power on. While
power is on, do not remove the front cover. Doing so can cause an
electric shock.
Do not touch the switches with wet hands. Doing so can cause an electric
shock.
A separate switch that makes an emergency stop must be provided. The
"STOP/RESET" key of the operation panel or parameter unit is valid for
stopping only when the function setting has been made. Not providing a
separate emergency switch may cause accidents.
When the stall prevention function is activated, operation will be performed
independently of the preset acceleration/deceleration time and preset
speed. The machine must be designed to ensure safety if the stall
prevention function is activated. Not doing so can cause accidents.
At the occurrence of an alarm, the run signal must be turned off before
resetting the alarm. The drive unit will restart abruptly if you reset the
alarm with the run signal on. This may result in injury.
At occurrence of an alarm, the run signal must be turned off. If you do not
turn off the run signal, the alarm may be reset due to power OFF-ON at
the occurrence of an instantaneous power failure or like, restarting the
drive unit suddenly. This may result in injury.
