• 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
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 = 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-Multi User's Manual (MEH457), 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.
• Do not turn the main circuit power (circuit breaker) ON or OFF in order to start or stop
inverter operation.
Doing so could cause failure.
• Do not touch the heat sink and braking resistor because they become very hot.
Doing so could cause burns.
• Setting the inverter to high speeds is easy. Before changing the frequency (speed) setting,
check the specifications of the motor and machinery.
• The brake function of the inverter does not provide mechanical holding means.
Injuries could occur.
