Overview of the product
This is a 2-phase microstep driver for use with a 2-phase stepping
motors. The use of a microstep drive, which electrically divides the
basic step angle of a 2-phase motor, offers reduced vibration and
noise in the low-speed range compared with the levels in full-step
mode.
• Do not turn the C.OFF (All windings off) input to “ON” while the
motor is operating. The motor will stop and lose its holding ability,
which may result in injury or damage to the equipment.
• Do not disassemble or modify the driver. This may cause injury.
Refer all such internal inspections and repairs to the branch or sales
office from which you purchased the product.

Safety precautions
The precautions described below are intended to prevent danger or
injury to the user and other personnel through safe, correct use of the
product. Use the product only after carefully reading and fully
understanding these instructions.
Warning
• Do not use the product in explosive or corrosive environments, in
the presence of flammable gases, locations subjected to splashing
water, or near combustibles.
• Assign qualified personnel the task of installing, wiring, operating/
controlling, inspecting and troubleshooting the product. Failure to
do so may result in fire or injury.
• Install the driver in an enclosure in order to prevent injury.
• Keep the driver’s input-power voltage within the specified range to
avoid fire.
• For the driver’s power supply, use a DC power supply with
reinforced insulation on its primary and secondary sides. Failure to
do so may result in electric shock.
• Connect the cables securely according to the wiring diagram in
order to prevent fire.
• Do not forcibly bend, pull or pinch the power cable or motor lead
wire. Doing so may result in fire.
• Turn off the driver power in the event of a power failure, or the motor
may suddenly start when the power is restored and may cause
injury or damage to equipment.
• If this product is used in an vertical application, be sure to provide a
measure for the position retention of moving parts. The motor loses
its holding torque when the power is turned off. Failure to provide
such a measure may cause the moving parts to fall, resulting in
injury or damage to the equipment.
Handling the product without observing the
instructions that accompany a “Warning” symbol may
