STF-Multi axis Series Hardware Manual

2 Getting Started

You need to make the following preparations:
• A power supply suitable for the drive, please read the section titled "Choosing the Right power
Supply" below to help you choose the right power supply.
• A stepper servo motor that matches the drive, read the "Recommended Motors" section below.
• A small flat-head screwdriver.
• A computer with Windows 7 / Windows 8 / Windows 10 (32-bit or 64-bit) operating system.
• One USB communication cable for drive parameter configuration.
• One network cable is used to connect the driver to the controller, or the driver to the driver.
• Install the Stepper Suite software (includes USB drivers and can be downloaded from the
MOONS' website).
• Optional motor extension cord (available separately) • Optional encoder extension cable
(available separately)

2.1 Choose a Power Suppl

The main considerations when choosing a power supply are the voltage and current requirements
of the application.

2.1.1 Voltage

STF Stepper-servo drivers and motors perform best when powered with 24 to 48V DC voltage.
The choice of voltage depends on the desired performance and acceptable heating of the motor
and drive (not to trigger self-overtemperature protection of the drive or damage to the motor due to
overheating). Higher power supply voltage can improve the high-speed performance of the motor,
but it will also increase the heat output. Therefore, the closer the selected power supply voltage is
to the nominal upper limit of the driver, the smaller the operating duty cycle (the proportion of time
between running and stopping) that the user is allowed to use, that is, the less time the customer
is allowed to continuously run the motor, otherwise the drive will overheat and self-protection.
The maximum allowable operating voltage range of STF05/10 multi-axis series drivers is 18~75V
DC voltage. When the supply voltage is below 18V, the STF05/10 driver may not work reliably. Do
not operate the STF05/10 drive at a DC voltage lower than 18V, otherwise the drive will give a low
voltage alarm, which may stop the drive.
When the STF05/10 driver uses a regulated power supply and the power supply voltage is
close to 75V, it is recommended to take voltage clamp measures at the power input to avoid the
situation that the power supply voltage is higher than 75V and the driver overvoltage alarm will
stop the driver. When the driver uses an unregulated power supply, ensure that the no-load output
voltage value of the power supply is not higher than 75V DC.
