Oriental Motor Super Vexta UD2115 2-Phase Stepper Motor Driver

Oriental Motor Super Vexta UD2115 2-Phase Stepper Motor Driver

The Oriental Motor Super Vexta UD2115 is an industrial stepper motor driver developed to provide controlled and consistent operation of compatible two-phase stepping motors. Its constant-current drive design helps regulate motor excitation, making it suitable for applications that require accurate rotational positioning and repeatable movement.

The driver receives control pulses and rotation-direction signals from an external controller, allowing users to integrate it into automated machinery and motion-control systems.

Key Features

• Constant-Current Drive: Regulates motor excitation current for controlled two-phase stepping motor operation.
• Two Operating Modes: Supports full-step operation at 1.8° per step and half-step operation at 0.9° per step.
• Pulse and Direction Control: Accepts external pulse and direction signals for controlling motor movement.
• Optically Isolated Inputs: Photocoupler-based signal inputs help improve noise immunity between the controller and driver.
• Automatic Current Reduction: Reduces motor current during standstill to help minimize heat generation.
• Overheat Protection: Automatically stops motor output when the internal temperature exceeds the specified protection threshold.
• Selectable Pulse Input Modes: Supports different pulse-control configurations through internal function switches.
• Compact Industrial Construction: Enclosed design with screw terminals for power, motor, and control connections.

Applications

The UD2115 driver is suitable for compatible motor-control applications, including:

• Industrial automation systems
• CNC and positioning equipment
• Automated machinery
• Precision movement systems
• Textile and packaging machines
• Robotics and motion-control projects
• Laboratory automation equipment
• Two-phase stepping motor applications

Control and Operation

The driver receives movement commands from an external controller through pulse and direction inputs. The pulse signals determine the stepping movement, while the direction input controls the direction of rotation.

Users can select full-step or half-step operation through the internal function switches. The driver also provides automatic current reduction when motor pulses stop, helping limit heat generation during standby.

Important Compatibility and Safety Notes

• Designed for compatible Oriental Motor two-phase stepping motors.
• Verify motor winding configuration and rated current before connection.
• The original UD2115 requires single-phase 100V AC ±10%, 50/60Hz input.
• A suitable transformer or compatible 100V AC supply is required when operating in a 220–240V country.
• Do not connect or disconnect motor wiring while the driver is powered.
• Follow the manufacturer’s wiring diagram and grounding instructions.
