1.5 Operation
Warning:
• Make sure the AC Drive capacity matches the parameter 13-00.
• Reduce the carrier frequency (parameter 11-01) if the cable from the AC Drive to the motor is greater than
80 ft (25m). A high-frequency current can be generated by stray capacitance between the cables and result
in an overcurrent trip of the AC Drive, an increase in leakage current, or an inaccurate current readout.
• Do NOT remove any protective covers or attempt any wiring while input power is applied. Connect all
power wiring and control wiring before applying input power. Always turn OFF the power supply before
attempting AC Drive installation and terminal wiring.
• Do not operate switches with wet hands. Electric shock may result.
• Do not touch any terminals before the capacitors have fully discharged. Internal capacitors hold a charge
after power supply has been removed. After disconnecting power, wait at least 10 minutes before touching
any wiring, circuit boards, or components. Check DC voltage between terminals B1/P or (+) and (-) does
not exceed 25V; otherwise, electric shock may result.
Caution:
• Do not connect a load to the motor while performing a rotational auto-tune.
• Make sure the motor can freely run and there is sufficient space around the motor when performing a
rotational auto-tune.
Warning:
• Do not connect or disconnect the motor during operation. This will cause the AC Drive to trip and may
cause damage to the AC Drive.
• Operations may start suddenly if an alarm or fault is reset with a run command active. Confirm that no run
command is active upon resetting the alarm or fault, otherwise accidents may occur.
• It provides an independent external hardware emergency switch which emergently shuts down the AC
Drive output in the case of danger.
• If automatic restart after power recovery (parameter 07-00) is enabled, the AC Drive will start automatically
after power is restored.
• Make sure it is safe to operate the AC Drive and motor before performing a rotational auto-tune.
• Do not touch AC Drive terminals when energized even if AC Drive has stopped, otherwise electric shock
may result.
• Do not remove covers or touch circuit boards while the power is on. Failure to comply could result in death
or serious injury.
• After the power is turned off, the cooling fan may continue to run for some time.
Caution:
• Do not touch heat-generating components such as heat sinks and braking resistors.
• Carefully check the performance of motor or machine before operating at high speed, otherwise injury may
result.
• Note the parameter settings related to the braking unit when applicable.
• Do not use the AC Drive braking function for mechanical holding, otherwise injury may result.
