Expansion slots: U1–U5 for communication/functional modules
Service port: RS232 (IndraWorks parameterization)
Firmware module: DSM02.1-FW (stores firmware, parameters, and enables quick replacement/backup)
Core Functions
Current/speed/position three-loop control for fast dynamics and high accuracy
DA02 enhanced analog interface: Improved noise filtering, higher signal stability, and stronger anti-interference capability compared to DA01
DSM02.1-FW firmware module: Preconfigured firmware, supports parameter backup/restore, simplifies drive replacement
Cabinet-internal cooling saves space in compact control cabinets
Modular design enables flexible expansion and easy maintenance
Comprehensive protection: overvoltage, undervoltage, overcurrent, short circuit, overtemperature, feedback loss
Supports torque, speed, and position control modes
Application Scenarios
Medium-to-large CNC machine tools and machining centers
Multi-axis synchronous production lines and handling robots
Printing, textile, and packaging machinery
General industrial automation with analog control systems (especially in high-noise environments)
Precision test benches and motion simulators
Applications requiring quick drive replacement with preloaded parameters
Usage and Maintenance
Mount vertically and ensure adequate cabinet ventilation
Maintain ambient temperature ≤45 °C during operation
Complete DC bus, control power, motor, feedback, and analog wiring before commissioning
Configure parameters via IndraWorks (or restore from DSM02.1-FW backup)
Clean internal fan/heat sink every 6 months; inspect terminals periodically
Calibrate control loops every 2 years
When replacing, transfer DSM02.1-FW to the new unit for instant parameter recovery
