■ Operation
■ Maintenance/Inspection
• Do not connect a three-phase power supply to the digital torque amplifier output terminals
U, V, and W.
Doing so may result in injury or fire.
• Securely fasten the screws for the power terminals and motor terminals.
Failure to do say may result in fire.
• To prevent unexpected accidents, test the motor with the motor shaft not connected to a
machine or load.
• To prevent unexpected accidents, run with limit switches or stoppers attached to both ends
of the magnet track.
Failure to do so may result in injury.
• Set parameters before operating the motor in connection with a machine..
Operating without making these settings may result in machine runaway and damage.
• After mounting on the machine, prior to the start of operation, make sure the emergency
stop can be applied at any time.
Failure to do so may result in injury.
• Do not touch the heat sink while the unit is running.
The high temperature may result in burns.
• Never touch the inside of the digital torque amplifier.
Doing so may result in electrical shock.
• Be sure no wiring is exposed when power is turned ON.
Failure to do so may result in electrical shock.
• Do not touch the terminals for five minutes following power OFF.
Electrical shock may result due to residual voltage.
• Do not change the wiring while power is ON.
Doing so may result in electrical shock or injury.
