ASDA-A User Manual Preface & Safety Precautions

iii

CAUTION

zDo not connect any power suppies to the U, V, W terminals. Failure to observe this

precaution may result in serious injury, damage to the drive or fire.

zEnsure 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

WARNING

zConduct trial run on the servo motor with motor shaft disconnected from its

mechanical system to avoid any accidents.

zDo not approach or touch any rotating parts (e.g. shaft) while the motor is running.

Failure to observe this precaution may result in serious injury to personnel.

zBefore starting the operation with a mechanical system connected, change the drive

parameters to match the user-defined parameters of the mechanical system.

Starting the operation without matching the correct parameters may result in servo

drive or motor damage, or damage to the mechanical system.

zEnsure that the emergency stop equipment or device is connected and working

correctly before operating the motor that is connected to a mechanical system.

zDo 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

WARNING

zDo not touch any internal or exposed parts of the servo drive as electric shock may

result.

zDo not remove the operation panel while the drive is connected to an electrical

power source otherwise electrical shock may result.

zWait 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 drive and motor with hazardous voltages even after power

has been removed.

zDo not disassemble the servo drive or motor as electric shock may result.

zDo not connect or disconnect wires or connectors while power is applied to the drive

and motor.

zOnly qualified personnel who have electrical knowledge should conduct

maintenance and inspection.

Main Circuit Wiring

CAUTION

zUse multi-stranded twisted-pair wires or multi-core shielded-pair wires for signal,

encoder (PG) feedback cables. The maximum length of command input cable is 3m

and the maximum length of encoder (PG) feedback cables is 20m.
