Safety Precautions
These safety precautions are very important. Read them before performing any pro-
cedures such as checking products on delivery, storage and transportation, installa-
tion, wiring, operation and inspection, or disposal. Be sure to always observe these
precautions thoroughly.
WARNING
• Never touch any rotating motor parts while the motor 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 product.
• 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 terminals 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 this manual for trial
operation.
Failure to do so may result not only in faulty operation and damage to equipment,
but also in personal injury.
• The multi-turn output range for the Σ-V Series absolute position detecting
system is different from that of earlier systems (15-bit and 12-bit encoders).
In particular, change the system to configure the Σ series infinite-length
positioning system with the Σ-V Series.
• The multi-turn limit value need not be changed except for special applica-
tions.
Changing it inappropriately or unintentionally can be dangerous.
• If the Multi-turn 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 front cover, cables, connectors, or optional items from
the upper front of the SERVOPACK while the power is ON.
Failure to observe this warning may result in electric shock.
• Do not damage, press, 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, fire, or damage to the product.
