Prevent Electrostatic Discharge
ATTENTION: This IC is sensitive to electrostatic discharge, which can cause internal
damage and affect normal operation. Follow these guidelines when you handle this IC:
・Touch a grounded object to discharge potential static.
・Wear an approved grounding wrist strap.
・Do not touch pins of this IC.
・Store this IC in appropriate static-safe packaging when not in use.
Safety Notice
WARNING: This IC is not designed or intended to be fail-safe, or for use in any
application requiring fail-safe performance, such as in life-support or safety devices or
systems that could lead to death, personal injury or severe property or environmental
damage (individually and collectively, "critical applications"). Customer must be fully
responsible for the use of this IC in critical applications.
Provide adequate design and operating safeguards in order to minimize risks
associated with customer's applications when incorporating this IC in a system.
Before you begin
ATTENTION: Before using this IC , read this manual thoroughly to ensure correct
usage within the scope of the specification such as the signal voltage, signal timing,
and operation parameter values.
Installation of this IC
ATTENTION: This IC is provided in the form of a lead-free package. The installation
conditions are different from those of the conventional lead-soldered IC. See Chapter
16 for the installation conditions of this IC.
Notes on S-curve acceleration/deceleration driving
ATTENTION: This IC is equipped with a function that performs decelerating stop
For a fixed pulse d rive with S-curve deceleration of the symmetrical acceleration
/deceleration. However, when the initial speed is set to an extremely low speed (10 or
less), slight premature termination or creep may occur. Before using a S-curve
deceleration drive, make sure that your system allows premature termination or creep.
