Wiring
¾Connect the ground terminals to a
¾Do not connect any power supplies to the U, V, W terminals. Failure to observe this precaution may result in serious injury, damage to the drive or fire.
¾Ensure that all screws, connectors and wire terminations are secure on the power supply, servo drive and motor. Failure to observe this caution may result in damage, fire or personal injury.
Operation
¾Before starting operation with a mechanical system connected, change the drive parameters to match the
¾Ensure that the emergency stop equipment or device is connected and working correctly before operating the motor that is connected to a mechanical system.
¾Do not approach or touch any rotating parts (e.g. shaft) while the motor is running. Failure to observe
this precaution may cause serious personal injury.
¾In order to prevent accidents, the initial trial run for servo motor should be conducted under no load conditions (separate the motor from its couplings and belts).
¾For the initial trial run, do not operate the servo motor while it is connected to its mechanical system. Connecting the motor to its mechanical system may cause damage or result in personal injury during the trail run. Connect the servo motor once it has successfully completed a trail run.
¾Caution: Please perform trial run without load first and then perform trial run with load connected. After the servo motor is running normally and regularly without load, then run servo motor with load connected. Ensure to perform trial run in this order to prevent unnecessary danger.
¾Do not touch either the drive heat sink or the motor during operation as they may become hot and personal injury may result.
Maintenance and Inspection
¾Do not touch any internal or exposed parts of servo drive and servo motor as electrical shock may result.
¾Do not remove the operation panel while the drive is connected to an electrical power source otherwise electrical shock may result.
¾Wait at least 10 minutes after power has been removed before touching any drive or motor terminals or
performing any wiring and/or inspection as an electrical charge may still remain in the servo drive and servo motor with hazardous voltages even after power has been removed.
¾Do not disassemble the servo drive or motor as electric shock may result.
¾Do not connect or disconnect wires or connectors while power is applied to the drive and motor.
¾Only qualified personnel who have electrical knowledge should conduct maintenance and inspection.
Main Circuit Wiring
¾Install the encoder cables in a separate conduit from the motor power cables to avoid signal noise. Separate the conduits by 30cm (11.8inches) above.
¾Use
of encoder (PG) feedback cables is 20m (65.62ft.).
¾ As a charge may still remain in the drive with hazardous voltages even after power has been removed, be sure to wait at least 10 minutes after power has been removed before performing any wiring and/or inspection.
¾It is not recommended to frequently power the drive on and off. Do not turn the drive off and on more
than once per minute as high charging currents within the internal capacitors may cause damage.
