Notes for Safe Operation

WARNING

• Never touch any rotating servomotor parts during operation.

Failure to observe this warning may result in injury.

• Before starting operation with a machine connected, make
sure that an emergency stop can be applied at any time.

Failure to observe this warning may result in injury or damage to
the equipment.

• Never touch the inside of the SERVOPACKs.

Failure to observe this warning may result in electric shock.

• Immediately after the power is turned OFF or after a voltage
resistance test, do not touch terminals.

Residual voltage may cause electric shock.

• Follow the procedures and instructions provided in the man­uals for the products being used in the trial operation.

Failure to do so may result not only in faulty operation and dam­age to equipment, but also in personal injury.

• The multiturn limit value need not be changed except for
special applications.

Changing it inappropriately or unintentionally can be dangerous.

• If the Multiturn Limit Disagreement alarm occurs, check the
setting of parameter Pn205 in the SERVOPACK to be sure
that it is correct.

If Fn013 is executed when an incorrect value is set in Pn205, an
incorrect value will be set in the encoder. The alarm will disappear
even if an incorrect value is set, but incorrect positions will be
detected, resulting in a dangerous situation where the machine will
move to unexpected positions.

• Do not remove the cables or connectors from the SERVO­PACK while the power is ON.

Failure to observe this warning may result in electric shock.
