- Software Configuration: Programmable resolution from 200 to 51,200 steps per revolution.
The user manual provides a DIP switch table with selectable settings up to 25,000 steps per revolution, while the current product page specifies 25,600 steps per revolution. For exact DIP switch settings, refer to the applicable DM2282 manual or software documentation.
Advanced Motion Control Technologies
Anti-Resonance
Anti-Resonance technology helps eliminate mid-range instability and provides optimal torque, contributing to smoother motor operation and improved motion stability.
Motor Self-Test and Parameter Auto-Configuration
The DM2282 can identify the connected motor's characteristics and automatically calculate the drive's current-loop parameters to optimize performance.
According to the user manual, this function can be activated by switching DIP switch SW4 twice within two seconds. The auto-configuration process takes approximately 1–3 seconds, during which the motor shaft may vibrate slightly.
Multi-Stepping Technology
Multi-Stepping allows a lower-resolution step input to produce a higher microstep output, helping achieve smoother motor movement without requiring the controller to generate the full microstep pulse frequency.
Control Modes and Communication
The DM2282 supports two main motion control modes:
- PUL/DIR: Separate pulse and direction signals.
- CW/CCW: Double-pulse control for clockwise and counter-clockwise movement.
The drive features three optically isolated control inputs and one fault output. Its RS232 communication port allows users to configure peak current, microstep resolution, active signal level, current-loop parameters, and Anti-Resonance parameters through the compatible Leadshine software.
Protection Functions
The DM2282 includes built-in protection functions to improve system reliability:
- Over-Current Protection: Activated when the drive's peak current exceeds the permitted limit.
- Over-Voltage Protection: Activated when the drive's operating voltage exceeds the permitted limit.
- Phase-Error Protection: Listed among the drive's protection functions in the user manual.
The drive also provides a fault output signal for external monitoring. The manual specifies that this output can sink or source up to 20 mA at 24 V.
