Safety Precautions

This section describes important precautions that must be followed during storage, transportation, installation,
wiring, operation, maintenance, inspection, and disposal. Be sure to always observe these precautions thor-
oughly.
• Never touch the rotating parts of the motor during operation or adjustments.
• Before starting operation with a machine connected, make sure that an emergency stop can be
• Never touch the inside of the power regeneration converters and SERVOPACKs.
• Do not remove the cover of power supply terminal while the power is ON.
• Do not touch terminals before the main-circuit capacitor has had time to discharge after the power
• Do not touch terminals while the charge indicator is lit.
• Do not touch terminals before the main-circuit capacitor has had time to discharge after voltage
• Make sure that trial operation was completed successfully before you make adjustments.
• Follow the procedures and instructions for the trial operation as noted in the applicable manual for
• The output range of multiturn data for Σ-V-SD driver absolute detection system differs from that for
• When you set up the absolute encoder, the multiturn data will change to between minus two and
• The multiturn limit value must be changed only for special applications.
• If the Multiturn Limit Disagreement alarm occurs, check the setting of parameter Pn205 in the SER-
• Do not remove the front cover, cables, connectors, or optional items on the foreside while the power
• Do not damage, press, exert excessive force or place heavy objects on the cables.
• Do not modify the product.

plus two turns. This will cause the reference position of the machine to change. Adjust the reference
position at the host controller to the correct position after you perform the setup.
If the machine is operated without aligning the position in the host controller, unintended operation may occur
and may result in injuries or damage to the machine. Be careful when starting the machine to ensure that this
does not occur.
Changing it inappropriately or unintentionally can be dangerous.

If the multiturn limit value setting is implemented while 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.
