Operation
• Be sure to install the terminal block cover before turning the power on. Do not remove the
cover during power application.
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 inverter may automatically restart after tripping,
depending on its cause, causing the motor driven by it to start rotating. In designing a
system or a facility using the motor driven by the FRENIC-Mini, make sure that such
automatic restart would not cause any personal injury, damage to equipment, or other
unintended incidents.
• If the stall prevention function has been selected, the inverter may operate at an
acceleration/deceleration time or frequency different from the set ones. Design the
machine so that safety is ensured even in such cases.
Otherwise an accident could occur.
• The
key is only effective when function setting (Function code F02) has been
established to enable the
key. Prepare an emergency stop switch separately. If you
disable the STOP key priority function and enable command (FWD) or (REV), you cannot
stop the inverter output by the
key on the built-in keypad.
• If an alarm reset is made 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 have selected "Active" as the mode of Restart after momentary power failure (F14 =
4 or 5), the inverter will automatically restart, causing the motor driven by it to start
rotating. In designing a system or a facility using the motor driven by the FRENIC-Mini,
make sure that safety is secured even in such instances.
• If you set the function codes wrongly or without completely understanding the instruction
manuals and the FRENIC-Mini User's Manual, the motor may rotate with a torque or at a
speed not permitted for the machine.
An accident or injuries could occur.
• Do not touch the inverter terminals while the power is applied to the inverter even if the
inverter stops.
Doing so could cause electric shock.
