• Re-supply power after 1 sec from disconnected power.
• Do not input CW, CCW signal at the same time in 2 pulse input method.
• When the signal input voltage is exceeded the rated voltage, connect additional resistance at
the outside.
• Set RUN current within the range of motor's rated current depending on the load.
When the rated motor current is exceeded, the heat may increased and motor may be
damaged.
• If the driver stops by the current down function, switches to STOP current.
If the current down function is not set or HOLD OFF signal is [H], STOP current switching will
not be executed.
• Use twisted pair (over 0.2 mm
) for the signal cable within 2 m.

• In case of extending the motor cable, use the cable that is thicker than lead cable.
• Keep the distance between power cable and signal cable over 10 cm.
• If the power is supplied while TEST switch is ON, the motor operates immediately and it may
be dangerous.
• Do not change any setting switches (function selection, RUN/STOP current, resolution) during
the operation or after supplying power.
Failure to follow this instruction may result in malfunction.
• Motor vibration and noise may occur in a specific frequency range.
- Change the motor installation method or attach the damper.
- Use the unit out of the corresponding frequency range due to changing motor RUN speed.
• Maintain and inspect regularly the following lists.
- Unwinding bolts and connection parts for the unit installation and load connection
- Abnormal sound from ball-bearing of the unit
- Damage and stress of lead cable of the unit
- Connection error with motor
- Inconsistency between the axis of motor output and the center, concentric (eccentric,
declination) of the load, etc.
• This product does not contain a protection function for a motor unit.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in 'Specifications')

• It is able to set the RUN current of the motor.
• When RUN current is increased, RUN torque of the motor is also increased.
• When RUN current is increased, the heat of the motor is also increased.
• Set RUN current for the load within range of the rated current of the motor.
• The setting must be changed when the motor stops.

• This function allows to control the current provided to motor for preventing severe motor
heat while motor stops.
• The setting is applied when using C/D (Current Down) function.
• STOP current setting value is % ratio of set RUN current.
E.g.) If the RUN current is 1.4 A, STOP current setting is 40%, the STOP current is 1.4 A×0.4 = 0.56 A.
• When STOP current is increased, RUN torque of the motor is also increased.
• When RUN current is increased, the heat of the motor is also increased.
• The setting must be changed when the motor stops.

• Two resolutions can be set with MS1, MS2 switch.
• MS1 or MS1 can be selected with DIVISION SELECTION signal. ([L]: MS1, [H]: MS2)
• It sets the step angle (rotation angle for 1 pulse).
• The set step angle is divided angle with set revolution by setting basic step angle of 0.72
• The set step angle is the angle divided by the set resolution of 0.72° basic step angle of
5-phase stepper motor.
• The divided step angle is based on following equation.

• This output indicates the beginning of the stepper motor excitation sequence, and allows to
know the rotational position of the motor shaft.
• Regardless of the resolution, th pulse is output every 7.2° rotation of motor shaft. (50 outputs
per motor rotation)
E.g.) Full step: 1 output for 10 input pulse, 20 division: 1 output for 200 input pulse
■ HOLD OFF
• This signal is for rotating motor shaft with external force or manual positioning.
- When HOLD OFF signal remains over 1 ms as [H], motor excitation is released.
- When HOLD OFF signal remains over 1 ms as [L], motor excitation is in normal status.
• Refer to 'I/O Circuit and Connections'.
• The setting must be changed when the motor stops.
