1. Introduction
STP-M112 is a 2-phase high speed Motionnet interfaced stepping motor driver. Encoder support and high
precision position drive simplifies the control of motion.
1.1. Precautions
1.1.1. Safety precautions
When you operate a stepper motor, you must take the utmost care to keep people from entering the zone in
which components are being moved by the motor. In addition, provide an emergency stop mechanism to stop
the motor operation instantly if a person is in danger.
1.1.2. Handling precautions
Inputting power
Do not connect or disconnect connectors and signal lines while this board or peripheral circuits are
supplied with power.
Static electricity
This board uses a CMOS device. Therefore this board must be stored in a package in which it was
shipped until you actually use it, in order to prevent damage from static electricity.
Switch settings
This board is equipped with switches to set details for serial communications and input/outputs. Be sure
to shut off the power supply to the board before changing these switches.
Connections to electrically noisy devices
Interference from excessively noisy devices or from power surges on the power and I/O circuits may
cause the board to malfunction. To connect to a device, which may generate electrical noise, we
recommend taking countermeasures, such as attaching a protective circuit to the input/output circuits.
However, it is best not to share the same power supply with noise generating sources.
