The N pole and S pole toothed gears are engaged with an offset ofhalf tooth. The bottom of a N pole tooth is aligned with the top of a
S pole tooth.
Each pulse moves the shaft by a quarter (1/4) tooth pitch while theN pole teeth and the S pole teeth are attracted and repulsed in turn.
Each of those rotations is called a “step”.
The motor has 50 teeth around the wheel, turning 1.8 degrees per
step, requiring 200 pulses to make a complete rotation with an
integer number of steps. In this way the motor can be turned by aprecise mechanical angle in high resolution.
The motor shaft rotates more than 100 times while the actuator
travels the entire stroke/span. The calculated resolution is greaterthan 1/20000*.

MSP10

PSN
SeriesThe below illustrations show cross section images of a stepping motor, called also “stepper motor” or “step motor.”
The stepping motor consists of two major components: a stator (stationary part) and a rotor (rotating part).
The rotor is a permanent magnetic rotating shaft,surrounded by eight electromagnets or coils of two phases
StatorDamper(A and B).

Basic rotating step per pulse of the two-phase stepping motor employed by theelectric actuators is 1.8 degrees, thus requiring 200 pulses to complete a full
360-degree rotation.
The exact number of pulses is controlled by a micro-processor.
The “Predictive Control” employed as a part of its control algorithm enables theactuator to smoothly stop at an exact position (angle) without overshooting.

AUTO-SETUP FUNCTION: MSP40 / MRP50
Auto-setup is the function for automatically adjusting the full-closed/-open positions and the seal
spring pressure when the actuator is mounted on a valve.
By entering the valve stroke length and the necessary seal spring contraction amount using theProgramming Unit (Model: PU-2A) or via Modbus communication, adjustments are performed
automatically, saving manual calibrations and reducing commissioning time.

You do not have to have the Programming Unit to use the auto-setup function.
If you do not have the Programming Unit or do not wish to use Modbus communication, all you have to do is filling
values of the valve stroke length and the necessary seal pressure in Ordering Information Sheet when you order the
product. Our factory will proceed with all settings for you for free of charge.
Auto-setup can be also performed by manipulating DIP switches equipped on the actuator unit.

SeriesStart the auto-setup process.
Firstly, the stem moves
downward until the plug hits thevalve seat. (If it reaches theextended end before hitting thevalve seat, the process isaborted as an error.)

Secondly, it moves upward for a
distance of the specified stroke.
(If it hits the upper side of thevalve seat before reaching thespecified length, the process isaborted as an error.)

Then it moves downward again
to the valve seat position andpresses further on by the
specified seal spring contraction
amount.
If there is no abnormality, thesetting is saved and the stem
goes back to 50% position tocomplete the setup.

Calibration is processed automatically by pressing keys on the Programming Unit after the actuator is mounted on a valve.

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
principle of 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 stator
SN
windings based on the command pulse, the motor rotates
S
S
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 manyusers and 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 andcountry in the market.

Contributing to Energy Saving
A typical countermeasure for cold environmentis a heater working on for 24 hours/365 days,
which inevitablly wastes energy to some extent.

Planetary Gear Mechanism

Stepping Motor

Thermal Control

The drive section employs a
stepping motor featuring no
mechanical contact structure
and long life. The minimum
rotating angle of the motor is
1.8 degrees per pulse, enablinghigh accuracy opening control.

The motor control circuit board
is separated from the otherelectronic circuits. The heatdissipation efficiency of theboard itself is also improved.

Endurable Gear Mechanism

Potentiometer for Position Detection

A planetary gear mechanism consists of two gears (the "planet")
revolving around the center of the other (the "sun"), just like theplanets revolve around the sun. A planetary carrier connects tothe centers of the two planetary gears and rotates, to rotate the

MSP
SeriesThe planetary gear mechanism can yield higher torque witha smaller number of gears compared from that required by a
combination of spur gears, resulting in compact size and small
backlash.

Dry bearings needing nolubrication are employed tobalance robustness of the
bearings and high reliability/
long life.

The class of potentiometer typicallyused for industrial vehicles orconstruction machines is used torealize vibration resistance, highquality and long life.

2-wire Position Transmitter
Model: VOS2T

Brushless Angle Sensor
Model: NRA

Brushless Angle Sensor ……
A type of angle sensor detecting positional
relationship between a fixed coil and a
movable coil, using the principle of magnetic
induction. It has no electrical sliding part,featuring high reliability and long life.

FEATURES· Light weight and compact· High precision and high resolution· Direct/Reverse action selectable· IP66 drip-proof enclosure
suitable for outdoor installation

Brushless Angle Sensor

The VOS2T is a 2-wire position transmitter incorporatinga brushless angle sensor. It detects the rotating angle ofpneumatic/electric actuators, and transmits 4 - 20 mA output
signal proportional to the angle.

The analog (MV) output (4 - 20 mA or other current/voltage range) of the SM10 can be used to
track a cascade (CAS) input (e.g. MV output from an external controller), or to provide a specificvalue for manual control.
