Core Functions
Current/speed/position three-loop control for high-precision motion
Internal air cooling saves cabinet space for dense layouts
Compact 60 mm width enables multi-axis integration
Digital feedback ensures high-resolution positioning and fast error detection
DA11 high-resolution analog interface for precise analog command control
Comprehensive protection: overvoltage, undervoltage, overcurrent, short circuit, overheating, feedback loss
Supports torque/speed/position control modes
Application Scenarios
CNC machine tools (mid-power axes with high-resolution analog control)
Printing/textile/packaging machinery
Robotics/handling systems with 10 A continuous current
High-precision analog-controlled automation retrofits
Light-duty spindle drives
Usage and Maintenance
Install with cabinet airflow ≥ 100 m³/h to ensure proper cooling
Operate below 45 °C to avoid performance derating
Configure DA11 analog range (±10 V) and feedback type via IndraWorks
Clean internal air passages every 6 months to prevent dust buildup
Calibrate control loops and feedback system annually
