LV8702VSLDGEVK

www.onsemi.com

Direction:

CW −Clockwise

CCW −Counter clockwise

NOTE: The direction of rotation may vary depending on

how the motor wires are connected to the

terminals.

5. Set the output motor current

The output current can be set within the limit value

(Box on the right) according to 10 by operating the

slider or the value of Box on the left.

The setting values are incremented by 0.01 A, but

the accuracy is limited due to the specifications of

the Arduino.

NOTE: The output current is set to 0.3 [A] for the

reference motor and the recommended adapter

at startup, and it is not necessary to set it again

for use in the same environment.

6. Set the step angle for the motor

NOTE: The step angle will vary depending on the

motor. If using the included reference motor,

please set it to 7.5°.

The step angle setting enables the “rpm” setting under

Motor Speed and “Degree” setting under Transfer Unit.

7. Set the motor speed in step/s or rpm

step/s (=pps): Frequency of the number of steps per second

rpm: Rotational speed of the motor per minute

Stepper motors are not intended for sudden acceleration,

and will vibrate if the control exceeds the maximum rotation

speed. When using the included reference motor with the

recommended AC adaptor, please set the rotation speed

according to the table below.

Full step 1~560 step/s 2~700 rpm

Half step

(Full−torque)

1~1120 step/s 1~700 rpm

Half step

(Smooth)

Quarter step 1~2240 step/s

8. Set the units and value of the transfer condition for

the control signal. After the specified transfer

condition elapses, the motor will stop and hold its

torque. Since current continues to flow to the

motor, it is important to pay attention to heat

generation. Please select the Free button to stop

powering the motor.

For an unspecified rotation time, select 0 (Infinity)

Example 1: Rotating the motor for 10 seconds

Transfer Unit = Seconds

Transfer Time = 10 [seconds]

Example 2: Rotating the motor for 100 steps

Transfer Unit = Steps

Transfer Step = 100 [steps]

LV8702VSLDGEVK

www.onsemi.com

xample 3: Rotating the motor 180 degrees

Transfer Unit = Degree

Transfer Angle = 180 [degree]

9. When the Start button is pressed, the motor will

rotate. If changes to the Output Current, Excitation

or Motor Speed are made, the changes will take

effect upon pressing the Start button.

To change the direction of rotation, it is

recommended to stop the motor first with the Stop

button, change the value, and then press the Start

button to begin the motor rotation.

Pressing the Stop button causes the motor to stop,

and hold the torque.

When the Free button is pressed, the motor will

stop and lose the torque.

To maintain the position while the motor rotates,

or to pause the motor and restart from the same

position, select the Stop button.

At this time, because of the current still flowing

to the motor, attention must again be paid to

heat generation.

10. Set the specifications of the power supply and

motor to be used.

Supply Voltage... Power supply voltage

MAX Supply Current... Maximum power supply

current

Motor Rated Current... Motor Rated Current

Motor Winding Resistance... Motor coil resistance

Max Output Current Set buttons ... Calculate the

maximum output current from the above four

setting values, and 5 limit the set range of the

output motor current to enable safer motor driving.

11. Set the high−efficiency drive function.

(This function does not work in slow speed and

fast speed range where the feedback signal can’t

be stably detected. This function cannot be

selected when Full Step is set.)

The high−efficiency drive function automatically

optimizes the motor current according to the motor

load and rotational speed. By turning on this

function, power consumption, heat, vibration, and

noise can be reduced. The high−efficiency drive

function consists of the following three

parameters.

Efficiency... ON/OFF of high−efficiency drive

function

When the high−efficiency drive function is turned

on, the motor current is automatically adjusted

within the range of the limit set in 5.

Drive Margin... Margin adjuster Function

Adjust the margin from the minimum current that

can rotate the motor.

When the margins are set to Small, the current

consumption is the smallest, but the number of

boost−ups may be increased for small

load−changes.

For this reason, set the margin to be larger for

applications with excessive load variation.

Boost Up... boost−up adjuster function

This process increases the motor current rapidly

and temporarily in order to maintain the motor

rotation in response to load variation.

Increasing the boost increases the rush load

resistance, but increasing the boost increases the

rotational stability.

The worsened of rotational stability can be

suppressed by increasing the Drive Margin.

It is possible to export the code to an Arduino

sketch (.ino) file that can be used with the Arduino

IDE.

Once the automatically generated code is imported

into the Arduino IDE, it is possible to mimic the

procedures from the GUI.

1) Generating and writing Arduino code

Pressing Generate Program will open a save file

dialog.

LV8702VSLDGEVK

www.onsemi.com

Please select the desired directory for the file to be

saved (e.g. Desktop or Documents) and click Save.

When using the GUI,

is the name of the program, so a different name

will need to be used to save the exported file.

Double click the newly saved Arduino program to

open the Arduino IDE.

The GUI and Arduino IDE cannot be connected to

a PC at the same time. To upload the Arduino

program, please exit or select Disconnect in the

GUI, and proceed working in the Arduino IDE.

Follow the instructions in the Quick Start Guide in

P3 “Compiling the Arduino Program – Write to

Arduino”.

2) Using the generated Arduino program

After each API operation in the generated

program, a delay(0) is inserted. By changing the

value of the argument (0)* to the delay function,

the user is able to freely adjust the rotation time,

as well as the interval time between each API call

execution. This can be used to achieve the desired

stand−alone operation.

*Parameter units are msec (1000th of a second).

For a delay of 1 second, use delay(1000).

[Example of changing the interval time]

NOTE

“motorRotationDeg(10, 720.0, 0, 0)”

will start the motor with Full step, CW, 10 Step/s,

and an angle of 720 deg

“delay(5000)”

will drive the motor for 5000[msec]

(5s)

“motorRotationStop()”

will stop the motor

After the time specified in the delay command has

elapsed, the next command will be executed.

If the delay setting is 0 or too short, some motor

operations will complete so quickly, that it will be

imperceptible.

NOTE: The delay setting at the beginning of the setup

method will execute in the case of a new USB

connection, Arduino reset, or upon uploading

a sketch to the Arduino. In this case, the

Arduino will delay for 5 seconds while writing

the initial settings.
