5 A-4 Overview Overview of Stepper s Stepper motors enable accurate positioning operation with ease. They are used in various types of equipment for accurate rotation angle and speed control using pulse signals. Features $ $ Accurate Positioning in Fine Steps A stepper motor rotates with a fixed step angle, just like the second hand of a clock. This angle is called "basic step angle." Oriental offers 5-phase stepper motors with a basic step angle of.72 and 2-phase stepper motors with a basic step angle of Stepper s (5 steps) Stepper s ( steps) $ $ Easy Control with Pulse Signals A system configuration for high accuracy positioning is shown below. The rotation angle and speed of the stepper motor can be controlled accurately using pulse signals from the controller. Controller Programmable Controller Pulse Signal Stepper Current Stepper and $ What is a Pulse Signal? A pulse signal is an electrical signal whose voltage level changes repeatedly between ON and OFF. Each ON/OFF cycle is counted as one pulse. A command with one pulse causes the motor output shaft to turn by one step. Voltage H Level L Level 1 Pulse Time $ The Amount of Rotation is Proportional to the Number of Pulses The amount of rotation of the stepper motor is proportional to the number of pulse signals (pulse number) given to the driver. The relationship of the stepper motor's rotation (rotation angle of the motor output shaft) and pulse number is expressed as follows: θ = θs A θ : Rotation angle of the motor output shaft [deg] θs : Step angle [deg/step] A : Pulse number [pulses] 1 Pulse 1 Pulses 125 Pulses $ The Speed is Proportional to the Pulse Speed The speed of the stepper motor is proportional to the speed of pulse signals (pulse frequency) given to the driver. The relationship of the pulse speed [Hz] and motor speed [r/min] is expressed as follows: θs N = f 6 N : Speed of the motor output shaft [r/min] 36 θs : Step angle [deg/step] f : Pulse speed [Hz] (Number of pulses input per second) 5 Hz 1 Hz Hz 6 r/min 15 r/min 1 r/min 3 r/min 24 r/min 6 r/min A-4 ORIENTAL MOTOR PRODUCT CATALOG 18/19

6 Stepper s A-5 $ $ Generating High Torque with a Compact Body Stepper motors generate high torque with a compact body. These features provide excellent acceleration and response characteristics, which in turn makes these motors well-suited for torque-demanding applications where the motor must be started and stopped frequently. To meet the need for greater torque at low speed, Oriental also has geared motors combining compact design and high torque. $ Frequent Starting/Stopping is Possible Speed Torque Characteristics [ frame size 6 mm (2.36 in.)] $ $ The Holds Itself at a Stopped Position Stepper motors continue to generate holding torque even at standstill. This means that the motor can be held at a stopped position without using a mechanical brake.

7 A-6 Overview Types Stepper motors come in several different types including the standard type, electromagnetic brake type and various geared types. The availability of such a wide selection means that you can choose an optimal type according to the function and performance required in your specific application. Typical examples are introduced below. Standard Type A basic model that is easy to use and designed with a balanced set of functions and characteristics. Electromagnetic Brake Type These motors incorporate a non-excitation type electromagnetic brake. When the power is accidentally cut off due to power outage or other unexpected event, the electromagnetic brake holds the load in position to prevent it from dropping or moving. Electromagnetic Brake Unit High-Resolution Type This motor's basic resolution is double that of the standard type. This results in high positioning accuracy and reduced vibration. Once the power is cut off, the electrical holding torque of the motor is lost and the motor can no longer be held at the stopped position in vertical operations or when an external force is applied. In lift and similar applications, use an electromagnetic brake type. Encoder Type Monitoring the current position and detecting positional errors are possible. For example, comparing the command position and current position enables you to check the normal operation of the motor. Encoder Geared Type These motors incorporate a dedicated position-control gearhead with reduced backlash to make the most of the high controllability of the motors. The gearhead ensures highly accurate, smooth operation, even in applications where a large torque is received.

8 Stepper s A-7 Types Built-in Controller Type AC With this type, the operating data is set in the driver, and is then selected and executed from the host system. Host system connection and control are performed with any of the following: I/O, Modbus (RTU), RS-485 communication, or FA network. By using a network converter (sold separately), CC-link, MECHATROLINK or EtherCAT communication is possible. FLEX is the collective name for products that support I/O control, Modbus (RTU) control, and FA network control via network converters. Basic Setting (Factory setting) Setting Operating Data and Changing Parameters Support software ( MEXE2 ) Setting using RS-485 communication is also possible.

The system configuration when using multi-axis control has been simplified. Setting can be done by support software or RS-485 communication. Pulse Input Type AC DC This type executes operations by inputting pulses into the driver. Control the motor using a positioning module (pulse generator). The support software (MEXE2) can be used to check the alarm history and monitor status information.

9 A-8 Overview Advantages of Geared s Using geared motors bring many advantages, such as speed reduction, high torque and high resolution. $ $ The Can Drive a Large Inertial Load If compared with a standard motor, the geared motors can drive larger inertial loads because its permissible load moment of inertia increases with the square of the gear ratio. This means that larger inertial loads can be driven with geared motors. $ Comparison of Load Moment of Inertia Type Standard Type Product Name PKE564AC Load Moment of Inertia (1 times of Rotor Inertia) kg m 2 (8.8 oz-in 2 ) Diameter of Inertial Load (Thickness: mm (.79 in.), material: Aluminum) 72 mm (2.83 in.) Speed Range 6, r/min PS Geared Type (Gear ratio 5) PKE566AC-PS kg m 2 (37 oz-in 2 ) 187 mm (7.36 in.) 6 r/min $ $ Improved Damping Characteristic at Start and Stop If the inertial load is large or acceleration/ deceleration time is short, a geared motor can reduce damping more effectively and thereby ensure more stable driving compared to a standard motor. Geared motors are ideal for applications where a large inertia such as an index table or arm must be driven to perform quick positioning. $ $ High Rigidity, Resistant to Torsional Force Geared motors have high rigidity and are resistant to torsional force. Therefore, compared to standard motors, geared motors are less subject to load torque fluctuation. This means that stability and high positioning accuracy can be ensured even when the load size changes. $ Application: Lifter The application can perform highprecision stops, even with elevators and other mechanisms that perform vertical operations where the number of loads or weight of loads changes. $ Application: Security Camera The position can be held securely even when the camera sways from strong winds.

10 Stepper s A-9 $ $ Downsizing If comparing the standard motor and the geared motor, which have similar maximum holding torque, the frame size of the geared motor is smaller than the standard motor.

(With geared types, the value of holding torque considers the permissible strength of the gear.) 2Rotor Inertia This refers to the inertia of the rotor inside the motor. This is necessary when the required torque (acceleration torque) for the motor is calculated. 3Rated Current The rated current is determined by the motor temperature rise. It is the current value that can flow to the motor windings continuously at motor standstill. As a general rule, the current setting must be the rated current. 4Basic Step Angle The resolution is the angular distance (in degrees) that the motor moves upon input of one pulse signal from the driver. It differs depending on the motor structure and excitation mode. 5Gear Ratio This is the ratio of the rotation speed between the input speed from the motor and the speed of the output gear shaft. For example, a gear ratio of 1 indicates that when the input speed from the motor is 1 r/min, the output gear shaft speed is 1 r/min. 6Permissible Torque The permissible torque represents the maximum value limited by the mechanical strength of the output gear shaft when operated at a constant speed. For the types other than the TS geared, PS geared, and harmonic geared types, the total torque including acceleration and deceleration torque should not exceed the permissible torque. 7Maximum Instantaneous Torque (TS geared, PS geared, and harmonic geared types) This is the maximum torque that can be applied to the gear output shaft during acceleration/deceleration such when an inertial load is started and stopped. 8Holding Torque at Standstill While Power is ON: Holding torque when the automatic current cutback function is active (factory setting) is shown. Electromagnetic Brake: Static friction torque when the electromagnetic brake is activated at standstill is shown. (Electromagnetic brake is power off activated type) 9Permissible Speed Range This is the range for rotation speed on the output gear shaft. 1Backlash This is the play of the output gear shaft when the motor shaft is fixed. When positioning in bi-direction, the positioning accuracy is affected. 11Power Supply Input The current value of the power input is the maximum input current value. (The input current varies according to the rotation speed.) 12Excitation Mode The driver has a function that can change the motor's step angle. The step angle value at which the motor can be operated is shown in the table. (The step angle value for microsteps is explained separately.) A-1 ORIENTAL MOTOR PRODUCT CATALOG 18/19

12 Stepper s A-11 How to Read Speed Torque Characteristics The characteristics diagram below shows the relationship between the speed and torque when a stepper motor is driven. The required speed and torque is always used when selecting a stepper motor. On the graph of characteristics, the horizontal axis expresses the speed at the motor output shaft, while the vertical axis expresses the torque. Torque [oz-in] Torque [N m] 1TH 3 fs 2 Speed [r/min] 2Pullout Torque The pullout torque is the maximum torque that can be output at a given speed. When selecting a motor, be sure that the required torque falls within this curve. The figure below shows the pullout torque when no clean damper or inertial load is installed (for reference). 3Maximum Starting Frequency (fs) This is the maximum pulse speed at which the motor can start and stop instantaneously (without an acceleration or deceleration time) when the frictional load and inertial load of the stepper motor are. Driving the motor at a pulse speed in excess of this rate will require a gradual acceleration/deceleration. This frequency drops when there is an inertial load on the motor. Overview & RK The speed torque characteristics are determined by the motor and driver, so they are greatly affected by the type of driver being used. 1Maximum Holding Torque This is the maximum holding torque (holding force) the stepper motor has when power is supplied (at rated current) but the motor is not rotating.
