Microstepping Motor & Driver with Built-in Controller

By: Oriental Motor  09-12-2011
Keywords: motor

3 Operating Modes

  • Direct Command - entry from terminal, PLC or master controller
  • Stand Alone Operation - running stored programs selected via I/O
  • Variable Data - any settable parameter or variable values entered/changed via direct entry from a host will be used by the stored sequence.

NEW! Self Correcting Function

When Self Correcting Function is enabled and synchronism is lost, the controller makes sure that the motion profile is completed correctly. Total distance remains the same.

*Self Correcting Function requires encoder motor to provide feedback to controller.

RS-485 Communications

  • Multi-drop up to 16 units
  • PLC or PC based programming
  • Warning, Error and Alarm detection

Motion Profile Examples

  • Repetitive positioning
  • Stop via sensor Input
  • Continuous operation at variable speeds
  • Linked motion, up to four maximum
  • Mechanical or Electrical Return to Home
  • PLS-OUT function - Drive a second driver with the same pulse count as the first motor.
  • Easily create basic motion such as Incremental, Absolute, Linked and Continuous moves
  • Use Program Editor to create complex motion profiles
  • Utilize commands from built-in editor with drag and drop
  • Easy cloning with Upload/Download functions to PC
  • Use Motion Monitor to view all inputs, outputs, motor position and alarm state
  • Built-in Help Menu

High-Resolution Type Motors

The positioning accuracy of a stepping motor is affected by the friction of the load.

The high-resolution motor type achieves high accuracy and reliability based on Oriental Motor's latest precision machining technology. The motor resolution is increased to double the level of a standard model to reduce the displacement angle against load torque, thereby acheiving high positioning accuracy. Vibration is also reduced.

The high-resolution type is designed with a stop position accuracy of 2 arc minutes (0.034°) [standard type: 3 arc minutes (0.05°)]. The reduced error helps improve the positioning accuracy of your equipment.

High-Torque Type Motors

The high-resolution type and high-torque type adopt a newly designed high-torque motor that widens the range of applications.

  • The smaller motor allows for compact equipment design.
  • The motor current is reduced to suppress heat generation.

Example: Avoidance of temperature rise in precision equipment or machinery.

Encoder Models Available

500 or 1000 pulse/rev.
