Trial Operation
• Disconnect the load (machine, device) from the motor before performing rotational autotuning or pole tuning.
The motor may turn, possibly resulting in injury or damage to equipment. Also, motor parameters cannot be correctly set with the motor
attached to a load.
• Stay clear of the motor until rotational autotuning or pole tuning has been successfully completed.
The motor could stop and then start again unexpectedly and this could result in injury.
• Always confirm the following before rotational autotuning and pole tuning:
• The lock key has been removed from the motor shaft.
• There are neither people nor objects around the motor shaft.
• The motor is at a complete stop.
Failure to do so may result in injury.
• Be careful when handling the shaft and coupling.
Failure to do so may result in injury.
• Be careful not to injure yourself with the key groove when turning the motor shaft by hand.
Failure to do so may result in injury.
• When operating a permanent magnet motor for the first time, or after exchanging a permanent magnet motor or an
Inverter, set a correct motor parameter to the Inverter before the operation, and be sure to check the motor speed detec-
tion.
Shortage of torque may be the cause when the motor is pulled in the load direction or when the motor does not run as
directed, such as reverses, doesn't work, or over-accelerates. (For details, refer to the instruction manual and the sup-
plemental manual.)
• Do not change the parameter settings unnecessarily.
Doing so may impede motor operation.
• When running a permanent magnet motor, be sure to set the following parameters.
• Motor related parameters (E1-
, E5-
)
• Parameters for PG open-circuit detection function (F1-
)
• Parameters for excessive speed deviation detection function (F1-
)
• Parameters for over-acceleration detection function (S3-
)
Failure to do so will cause damage to the equipment.
• If running a permanent magnet motor with any option cards other than the PG-F2 card and not using the braking
sequence recommended by this Inverter, set the following braking sequences externally.
• After inputting the operational order, or closing the pole detection complete signal, release the braking.
A basket will be pulled by a counter weight. Be careful of this, as it can cause injury.
• If running a permanent magnet motor with any option cards other than the PG-F2 card, note that the Inverter has not
been adapted for use with batteries. If so, do not select the battery as the power source for an operation.
Shortage of torque may be the cause when the motor is pulled in the load direction or when the motor does not run as
directed, such as reverses, doesn't work, or over-accelerates.
• Check to be sure that the front cover is attached before turning ON the power supply.
Failure to do so may result in electric shock.
• Provide a separate fast stop switch; the Digital Operator STOP Key is valid only when its function is set.
Failure to do so may result in injury.
• Reset alarms only after confirming that the RUN signal is OFF.
Failure to do so may result in injury.
• Do not touch the radiation fins (heatsink), braking resistor, or Braking Resistor Unit. These can become very hot.
Failure to do so may result in burn injury.
• Be sure that the motor and machine is within the applicable range before starting operation.
Failure to do so may result in injury.
• Provide a separate holding brake if necessary.
Always construct the external sequence to confirm that the holding brake is activated in the event of an emergency, a power fail-
ure, or an abnormality in the Inverter.
Failure to do so may result in injury.
• If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevator from dropping.
Failure to do so may result in injury.
• Do not check signals while the Inverter is running.
Failure to do so will cause damage to the equipment.
• Be careful when changing Inverter settings. The Inverter is factory set to suitable settings.
Failure to do so will cause damage to the equipment.
