Safety Precautions
These safety precautions are very important. Read them before performing any procedures such as checking
products on delivery, storage and transportation, installation, 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 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 indicator is ON.
Residual voltage may cause electric shock.
• Follow the procedures and instructions provided in the user's manual for the relevant products 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 serial data output range for the Σ-V Series absolute position detecting system is dif-
ferent from that of earlier systems with 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 applications.
Changing it inappropriately or unintentionally can be dangerous.
• If the Multi-turn Limit Disagreement alarm occurs, check the setting of parameter Pn205 in the SER-
VOPACK to be sure that it is correct.
If Fn013 is executed when an incorrect parameter value is set, 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 products.
Failure to observe this warning may result in injury, damage to products or fire.
• Provide an appropriate stopping device on the machine side to ensure safety.
The holding brake on a servomotor with a brake is not a stopping device for ensuring safety.
Failure to observe this warning may result in injury.
• Do not approach the machine when an instantaneous power interruption has occurred because the
machine may restart suddenly when the power is recovered. Secure the safety of people around
the machine when the machine restarts.
Failure to observe this warning may result in injury.
• Connect the ground terminal according to local electrical codes (100 Ω or less for a SERVOPACK
with a 100 V, 200 V power supply, 10 Ω or less for a SERVOPACK with a 400 V power supply).
Improper grounding may result in electric shock or fire.
• Installation, disassembly, or repair must be performed only by authorized personnel.
Failure to observe this warning may result in electric shock or injury.
• The person who designs a system using the safety function (Hard Wire Baseblock function) must
have full knowledge of the related safety standards and full understanding of the instructions in this
manual.
Failure to observe this warning may result in injury or damage to the product.
