1.Notes (Please be sure to read before using)

1-1 Installation

You shall observe the following installation method when installing this driver.

Please install the driver in the place where the air around the driver within 5 cm has air convection

with a rated temperature (40 ° C or lower temperature).

When using multiple axes please leave a space of 10 mm or more between each driver.

1-2 Connection of Connector

In particular, please pay attention to power wiring. This driver has a power circuit configuration that resists

breaking even with the incorrect polarity of the power supply, but the driver will be damaged if you wire the

power supply to the motor output terminal.

Please observe the instruction about wire materials and a length of stripped bare wire that is shown in the

section 3..Also, tighten the terminal block screw with a torque of 0.22 to 0.24 Nm. This prevents loosening

of screws and disconnection of wires.

1-3 Division of Micro step

Since a Division of Micro Step is performed by vector splitting currents of PhaseAand Phase Bof a stepping

motor by approximate sinusoidal wave electrically, a divided one-step-angle does not guarantee a

mechanical position accuracy as is.

The mechanical positional accuracy depends upon the machine accuracy of a motor's own and a driven

device.

1-4 Heat generation of a motor

Since surface of a motor may become extremely high temperature while driving, please care burns.

If a surface temperature of a motor exceeds 100℃, the motor may be damaged. So then reduce the current

value with "RUN “potentiometer or cool the motor by forced air cooling to not exceed 100 ℃.

It also can prevent heat generation by enabling Auto Current Down function and reducing a current during

stop.

1-5 Electric current value of Micro Step

A setting electric current value by "RUN" potentiometer is a peak value of approximate sinusoidal current.

1-6 Unipolar type motor drive

Although this driver is mainly designed for bipolar type motors, it can also drive unipolar type motors.

Please refer to the section 6-2 for wire connection method.

1-7 Compatibility notice to the customers using SD4030B2.

This driver is upward compatible with SD4030B2, but Mix Decay setting has been changed from a

potentiometer to a switch. For more detailed information, Refer to the section 18.

Outer form size and installation mounting pitch has not be changed.

In case of Open collector driven

Note 1) When circuit is driven at + 24V, connect a resistor of 1 W, 2 kΩ (recommend) in series.

When using a resistor other than 2 kΩ, use the resistance value that satisfies the current value in the

figure.

Note 2) In case of Open collector driven, the cable length should be within 1m.

In case of Line driver driven

4-2 Excitation off (OFF) input

Note) When circuit is driven at + 24V, connect a resistor of 0.5W, 2 kΩ (recommend) in series.

When using a resistor other than 2 kΩ, use the resistance value that satisfies the current value in the

figure.
