5 Notes for Safe Operation
Read this manual thoroughly before checking products on delivery, storage and transportation,
installation, wiring, operation and inspection, and disposal of the AC servo drives.
• 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.
• Never touch the inside of the SERVOPACKs.
Failure to observe this warning may result in electric shock.
• Do not remove the panel cover while the power is ON.
Failure to observe this warning may result in electric shock.
• Do not touch terminals for five minutes after the power is turned OFF.
Residual voltage may cause electric shock.
• Do not touch terminals for five minutes after voltage resistance test.
Residual voltage may cause electric shock.
• Follow the procedures and instructions for trial operation precisely as noted in the
Σ

ΙΙΙ
series User’s
Manual (Manual No.: SIEPS80000000A).
• Follow the procedures and instructions for the trial operation as noted in the applicable manual for
that product.
Malfunctions that occur after the servomotor is connected to the equipment not only damage the equipment,
but may also cause an accident resulting in death or injury.
• The output range of multi-turn data for
Σ
-
ΙΙΙ
series absolute detection system differs from that for con-
ventional systems (15-bit encoder and 12-bit encoder). Especially when “Infinite length positioning
system”
of conventional type is to be configured with
Σ
-
ΙΙΙ
series, be sure to make the system modi-
fication.
• 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 SER-
VOPACK 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 dan-
gerous situation where the machine will move to unexpected positions.
