    STM11 Hardware Manual 2 Getting Started The following items are needed: • A 15-30 volt DC power supply (24VDC is recommended), see the section below entitled “Choosing a Power Supply” for help in choosing the right one • Download ST Configurator and Q Programmer software from MOONS’ website •...

  • Page 8: Choosing A Power Supply

    STM11 Hardware Manual 2.3 Choosing a Power Supply The main considerations when choosing a power supply are the voltage and current requirements for the application. 2.3.1 Voltage Selection The STM11 is designed to give optimum performance at 24 VDC . The extended range of operation can be as low as 14VDC minimum and as high as 32 VDC maximum.

  • Page 9: Current

    STM11 Hardware Manual 2.3.2 Current The power supply current required by the STM11 at 24VDC input is shown in the charts below. Note that the supply current flowing into the STM11 is less than the motor phase current. That’s because the STM11’s switching amplifier converts high voltage and low current from the DC power supply into the higher current and lower voltage required by the motor.

  • Page 22: Drive/Motor Heating

    STM11 Hardware Manual 4.4 Drive/Motor Heating Step motors convert electrical power from the driver into mechanical power to move a load. Because step motors are not 100% efficient, some of the electrical power turns into heat as it passes through the motor. The amount of heating is not so much dependent on the load being driven as on the motor speed and power supply voltage.
