WARNING
• The drive must be securely grounded.
Otherwise, electric shock or fire could occur.
• Wiring must only be performed only by a qualified
electrician.
• Be sure to do all wiring after installing the drive unit.
Otherwise, electric shock or injuries could occur.
• Ground the drive according to the requirements of
national and local industrial safety regulations.
Otherwise, electric shock could occur.
• Check that the number of phases and the rated volt-
age of the product agree with the number of phases
and the voltage of the ac power supply.
Otherwise fire or an accident could occur.
• Do not connect the ac power source cables to the
drive output terminals U, V, and W.
• Do not connect a braking resistor to the dc link
circuit terminals P (+) and N (-).
Doing so could cause fire or an accident.
• Wire the 3-phase motor to the drive’s output
terminals U, V, and W, aligning phases each other.
Otherwise injuries could occur.
• The drive, motor and wiring generate electric noise.
which could interfere with nearby sensors or other
devices. To prevent the motor from malfunctioning,
take appropriate noise control measures.
Otherwise an accident could occur.
Operation
WARNING
• Be sure to install the terminal cover before turning
the power on. Do not remove the cover while power
is applied.
Otherwise electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the Retry function has been enabled, the drive
may automatically restart after tripping. Make sure
that any automatic restart can not result in material
damage or personal injury.
• If the Stall Prevention function has been selected,
the drive may operate with acceleration/deceleration
times or frequencies different from those selected.
The drive installation must be such that safety is
ensured if this occurs.
Otherwise an accident could occur.
WARNING
• The STOP key is only effective when enabled by
the correspnding function setting (function code
F02). For safety, a separate emergency stop switch
should always be installed. If you disable the STOP
key priority function and activate the (FWD) or (REV)
commands, it will no longer be possible to stop the
motor using the STOP key on the built-in keypad.
• If an alarm reset happens with the operation signal
turned on, a sudden start will occur. Check that the
operation signal is turned off in advance.
Otherwise an accident could occur.
• If you enable the Auto Restart function in the restart
mode after an instantaneous power failure (function
code F14), the drive will automatically restart the
motor when power is restored.
• If you set the function codes wrongly or without
completely understanding the instruction manual
and the AF-300 Mini User’s Manual, the motor may
operate at a torque or speed not authorized for the
driven load.
An accident or injuries could occur.
• Do not touch the drive terminals while power is
applied to the drive, even if the drive stops.
Doing so could cause electric shock.
• Do not turn the main circuit power on or off in order
to start or stop the drive. Doing so could result in
drive failure.
• Do not touch the heat sink or braking resistor, both
of which can become very hot in operation.
Doing so could cause burns.
• It is possible to set the drive to operate at speeds
higher than allowed by the driven load. Check the
performance of the motor and connected load
before changing the setting.
• The brake function of the drive does not provide
mechanical holding means.
Injuries could occur.
