Notes for Safe Operation
Read this manual thoroughly before checking products on delivery, storage and trans-
portation, installation, wiring, operation and inspection, and disposal of the AC ser-
vodrives.
WARNING
• Never touch any rotating servomotor parts while the servomotor is running.
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.
• Do not remove the cover of the power supply terminal block while the power
is ON.
Failure to observe this warning may result in electric shock.
• After the power is turned OFF or after a voltage resistance test, do not
touch terminals while the CHARGE lamp is ON.
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 output range of the rotational serial data for the Σ-V absolute position
detecting system is different from that of earlier systems for 12-bit and 15-
bit encoders. As a result, the infinite-length positioning system of the Σ
Series must be changed for use with products in the Σ-V Series.
• The multiturn limit value need not be changed except for special applica-
tions.
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 top front cover, cables, connectors, or optional items
from the SERVOPACK while the power is ON.
Failure to observe this warning may result in electric shock.
• Do not damage, pull, exert excessive force on, or place heavy objects on
the cables.
Failure to observe this warning may result in electric shock, stopping operation of
the product, or fire.
• Do not modify the product.
Failure to observe this warning may result in injury, damage to the equipment, or
fire.
