• Even if the power is off, do not remove the servo drive cover

Fire Safety Precautions

• Install the servo drive, the servo motor, and the regenerative resistor on non-combustible materials.
• Disconnect the input power if the servo drive malfunctions.
• Servo motor over-temperature sensing is not provided by the servo drive. Please use a thermal sensor, etc. for thermal protection of the servo motor.
• To prevent a fire, use a molded-case circuit breaker or fuse for the input power supply.

Repair and Inspection Precautions

• Before performing servicing tasks, turn off the power. Wait 15 minutes until the charge lamp goes off, and then check the voltage with a voltage tester.

Wiring Precautions

• ****Always use AC200~230[V] power input for the servo drive.
• Always connect the servo drive to the protective earth (PE) terminal.
• Branch circuit protection shall be provided per the NEC (National Electrical Code).
• Be sure to use a molded-case circuit breaker when you perform wiring for the servo drive.
• When you perform wiring for the servo drive, be sure to install a noise filter on the main power to satisfy EMI specifications.
• Do not connect commercial power directly to the servo motor.
• Do not connect commercial power directly to the U, V, W output terminals of the servo drive.
• Connect the U, V, W output terminals of the servo drive directly to the U, V, W input terminals of the servo motor, but do not install magnetic contactors between the ires.
• For connection, use copper wires.
• Always use pressurized terminals with insulation tubes when connecting the servo drive power terminal.
• When wiring, be sure to separate the U, V, and W cables for the servo motor power and encoder cable. Use our own designated cables. To use other cables, check the rated current of the servo motor, and consider the operating environment to select appropriate cables.
• Be sure to use twisted-pair shield wires for encoder and I/O signal cables.
• Always use the robot cable if the servo motor moves.
• Before wiring the power lines, turn off the input power of the servo drive and then wait until the capacitor is completely discharged.
• L7C Series do not provide an internal regenerative resistor. If the regenerative capacity is higher because of
  frequent acceleration and deceleration, connect an external regenerative resistor to B and B+.

Initial Setup Precautions

• Check the input voltage and power unit wiring before supplying power to the device.
• The servo must be in the OFF mode when you turn on the power.
• Be sure to check the motor ID, encoder type, and encoder pulse before supplying power.
• First set the motor ID [0x2000], encoder type [0x2001] and encoder pulse [0x2002] after turning on the power.
• After you complete the above settings, set the drive mode for the servo drive that is connected to the upper-level controller in [0x6060].
• Refer to the manual to perform I/O wiring for the servo drive according to each drive mode.
• You can check the on/off status of each I/O contact point from the digital input of [0x60FD].

Usage Precautions

• Install an emergency cut-off switch, which immediately stops operation in an emergency.
• Reset the alarm when the servo is off. Be warned that the system restarts immediately if the alarm is reset while the servo is on.
• Use a noise filter or DC reactor to minimize electromagnetic interference. This prevents nearby electrical devices from malfunctioning due to electromagnetic interference.
• This servo drive has solid-state servo motor overload protection. (Overload protection will be activated when it exceeds 100% of the drive rated current or more than the motor rated current.)
• Do not incinerate the servo drive. Harmful gas may be released if the servo drive is burned.
• Only use approved servo drive and servo motor combinations.
• The electric brake on the servo motor stops operation. Do not use it for ordinary braking.
• For the wiring diagram of the electric brake-type motor, refer to the guidebook on the homepage.
• Brake failure may occur if the electric brake is degraded or the mechanical structure is improper (for example, if the ball screw and servo motor are combined via the timing belt). Install an emergency stop device to ensure mechanical safety.

Malfunction Precautions

• Install a servo motor with an electric brake or separate the brake system for use during emergencies or device malfunctions.
• If an alarm occurs, solve the underlying cause of the problem. After ensuring safe operation, deactivate the alarm and resume operation.
• Do not approach the machine until the problem is solved.
