Operation
• Be sure to install the terminal block cover and the front cover before turning the power ON. Do not
remove the covers 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 selected, the inverter may automatically restart and drive the motor
depending on the cause of tripping.
(Design the machinery or equipment so that human safety is ensured after restarting.)
• If the stall prevention function (current limiter), automatic deceleration, and overload prevention control
have been selected, the inverter may operate at an acceleration/deceleration time or frequency
different from the commanded ones. Design the machine so that safety is ensured even in such cases.
Otherwise an accident could occur.
• The
key on the keypad is effective only when the keypad operation is enabled with function code
F02 (= 0, 2 or 3). When the keypad operation is disabled, prepare an emergency stop switch separately
for safe operations.
Switching the run command source from keypad (local) to external equipment (remote) by turning ON
the "Enable communications link" command (LE) or "Switch run command 2/1" command (FR2/FR1),
disables the
key. To enable the key for an emergency stop, select the STOP key priority with
function code H96 (= 1 or 3).
• If an alarm reset is made with the Run command signal turned ON, a sudden start will occur. Ensure that
the Run command signal is turned OFF in advance.
Otherwise an accident could occur.
• If you enable the "Restart mode after momentary power failure" (Function code F14 = 3, 4, or 5), then
the inverter automatically restarts running the motor when the power is recovered.
(Design the machinery or equipment so that human safety is ensured after restarting.)
• If you set the function codes wrongly or without completely understanding this instruction manual and
the FRENIC-Eco 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.
