Yaskawa Sigma-5 Safety Precautions for SGDV Servo Amplifier - Manual (Page 5)

E-3
• The multi-turn limit value must be changed only 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 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 on the foreside while the power is ON.
Failure to observe this warning may result in electric shock.
• Do not damage, press, exert excessive force or place heavy
objects on the cables.
Failure to observe this warning may result in electric shock, stop-
ping operation of the product, or fire.
• Do not modify the product.
Failure to observe this warning may result in injury, damage to the
product, or fire.
• Provide an appropriate stopping device on the machine side
to ensure safety. A holding brake for a servomotor with
brake is not a stopping device for ensuring safety.
Failure to observe this warning may result in injury.
• Do not come close to the machine immediately after reset-
ting momentary power loss to avoid an unexpected restart.
Take appropriate measures to ensure safety against an
unexpected restart.
Failure to observe this warning may result in injury.
• Connect the ground terminal to electrical codes (ground
resistance: 100 Ω or less for a SERVOPACK with a 200 V/
100 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.
