Guidance 1 Stepping Motor
A stepping motor rotates by a constant angle per pulse.
A stepping motor, also called a pulse motor, is a motor that rotates in synchronization with a command pulse signal. The principleof rotation of a simplified 2-phase, 8-pole stepping motor model is shown in the figure below.
A stepping motor consists of a stator with windings and arotor using a powerful neodymium magnet. Energizing theNSstator windings to generate a magnetic force is called
StatorStatorexcitation. By sequentially exciting the multiple statorSN
windings based on the command pulse, the motor rotatesSS
stepwise, utilizing the action of attraction and repulsion
Rotor
Rotor
between the magnetic poles of the stator and rotor. The(Permanent magnet)(Permanent magnet)
rotation angle of a stepping motor is always determined by
the constant mechanical accuracy (motor structure andmachining accuracy) for each command pulse signal.
Therefore, a stepping motor performs highly accurate
positioning control.

Guidance 2 Open Network
An open network is an industrial network, the specifications of which are made public and can be commonly used by many usersand manufacturers.
Open networks are roughly divided into the following two types.
1. Those specified by organizations and associations in consultation and recognized as official standards.
2. Those developed by specific manufacturers and organizations and established as de facto standards as a result of promotion
activities.
Both types have well-organized and integrated specifications and are available to everyone for many purposes. Either one canconnect different manufacturers’ devices (multivendor devices) and brings many benefits to users.
Currently, many types of open networks are expanding their tempo of popularization according to the applicable field and country
in the market.
