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 Phase A and Phase B of 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.

5.Logic of Command Input pulse

5-1 In case of 1-pulse mode Command pulse is counted at Up-edge of the internal photo coupler outputs. When a motor is in a normal connection, Command Direction is; CW when the internal photo coupler output is "LOW" and CCW when the internal photo coupler output is "HIGH". Output of the photo coupler is LOW when the primary LED is ON. Please note that direction of motor rotation varies also by wire connection. Timing chart is shown in the following figure.

5-2 In case of 2-pulses mode Command pulse is counted at Up-edge of photo coupler outputs. Each input becomes stand-by mode at the high level (photo coupler OFF). A motor rotates CW direction by pulses input to P1, or rotates CCW direction by the pulses input to P2. Please note that direction of motor rotation varies also by wire connection. Timing chart is shown in the following figure.

6.Connection of Motor

6-1 In the case of Bipolar type motor

6-2 In the case of Unipolar type motor Wiring method 1: With same current settings as a unipolar microstep driver, the torque and heat that is generated by a motor are almost the same. Please use this wiring method in usual.

Wiring method 2: It is effective method for using a motor at low speed with high torque. To make motor heat
generation equivalent to wiring method 1, please limit the maximum current to 70%.
However, the torque generated in the low speed range is 1.4 times of usual but an inductance of the coil is
four times than the method 1, a torque drops sharply against an increasing rotation speed.

8.Setting of switch SW 3(MIX)

Four types of setting are possible with the switch for adjusting Mix Decay function.
Mix Decay function has effect of reducing vibration of a motor by controlling slope of electric current
attenuation within a PWM cycle. Since the optimum ratio of Slow Decay setting at each motor rotation speed
is different, it is recommended that a customer may select the optimum switch position while checking
vibration at the motor speed you need.
In general, vibration declines when a Slow Decay ratio is larger at ultra-low speed area. On the other hand,
vibration declines when set a Slow Decay ratio smaller at a faster rotation speed.

10.LED“POW”

LED lights green when power is turned on. If the LED does not light even when power is turned on, there is
a possibility that Polarity of the power supply connected may be reversed, or that the power module may
have been damaged by wiring mistake.
Since this driver has a power circuit configuration that resists breaking even with the incorrect polarity of the
power supply, please turn the power on again after correcting the connection. If the power module is broken,
a whole unit shall be replaced.
Regarding location of the LED, refer layout diagram in the page 14 .

11.JOG operation

JOG operation by PUSH switch becomes enable when SW1-5 is ON.
When performing JOG operation, remove CN2, and set JP1 to 1-pulse mode.
Select Direction of rotation with SW1 - 6, and change a pulse frequency with "JOG" potentiometer.
JOG operation should be only used for trial operation of a driver and motor, and please operate with a motor
alone. Never use JOG operation after mounting this unit into other equipment, since it is dangerous to use
JOG operation then.
Be sure to turn off SW1-5 and 6 for normal Pulse Input operation

13.How to adjust the RUN potentiometer precisely

Prepare a DC ammeter. Before turning on the power supply, connect the positive side of the ammeter to the
phase A of connector CN1, and the negative side of the ammeter to the phase A of a motor. Turn off SW1-4
of the driver.
Then turn on the power supply and adjust with the RUN potentiometer to a target current value.

14.Need of a rated output current reduction at a higher power supply voltage area

When a power supply voltage exceeds 24 V and a motor is used in continuous rotation, please reduce a
peak current value according to the graph below.

19.CE Marking

SD4030B3 had performed tests for a driver and a motor individually that based on the following standards,
and had made the self-declaration of CE marking.
As for the EMC directive conformity, hence a condition varies depending on a customer's equipment
configuration with this driver and motor installed, so the customer should confirm the conformity of whole
devices by your own responsibility.
