Overview of Controllers
At Oriental Motor, a device that outputs pulse signals needed to operate a stepping motor is called a "Controller." Controllers let you make various settings to control your motor and also permit connection with a host programmable controller and sensors. Select a controller that best suits your system.
Features
Setting Positioning Operation Parameters
You can set desired positioning operation parameters (number of operation pulses, starting pulse speed, operating pulse speed, acceleration/deceleration rate, etc.).
Data Setting
- Starting Pulse Speed (VS) [Hz]
The frequency at which output of pulse signals is started. The controller starts outputting pulse signals at the frequency specified by the starting pulse speed, and increases the frequency along the slope specified by the acceleration/deceleration rate. - Operating Pulse Speed (VR) [Hz]
The target pulse signal frequency. This frequency dictates the operating speed of the motor. - Acceleration/Deceleration Rate (TR) [msec/kHz] or [sec]
The slope along which the pulse signal frequency is raised (acceleration) or lowered (deceleration).
The specific method to set data varies from one product to another depending on, for example, whether a dedicated operator interface unit is used or a computer is used. For details, refer to the page explaining each product.
Operation System
When the equipment is to be operated automatically, provide a programmable controller to serve as the host of your controller.
Offering Functions to Facilitate Motor Control
Return to Mechanical Home Function To perform accurate positioning operation, the mechanical home that defines the reference point must be determined accurately. Oriental Motor's controllers are equipped with the "Automatic return to home function." All you need is to wire a home sensor, and you can utilize this home detection function right away.
I/O Check Function
You can check the connection (I/Os) with the programmable controller.
Types of Controller
Stored Program Controller
These high-function controllers let you not only set motor positioning parameters and speeds, but also program various actions such as how the motor should operate according to the status of each general-purpose I/O and switching the output used to control an external device.
- Supporting conditional branching using general-purpose I/Os, wait processes using internal timers, and other operations based on sequence control.
- Single axis and dual axis types are available. The dual axis controller supports positioning operation based on linear interpolation.
Stored Data Controller
- With these controllers, you can operate the motor with ease by issuing a start signal from the host controller, as long as the speed, travel amount and other conditions for motor operation have been set.
- Stored data controllers are available in two types: those operated in the data-select positioning mode and others operated in the sequential positioning mode.
