Core Functions

Current/speed/position three-loop control for heavy-load dynamic response (bandwidth up to 2 kHz)

DA02 enhanced analog + encoder emulation: Higher resolution (16-bit vs DA01 12-bit) for precise analog control; 5 V differential encoder signals for noise immunity in long cables

Optimized internal cooling for continuous 150 A operation (low derating at 45 °C)

Modular design for flexible expansion and easy maintenance (hot-swap modules)

Full protection: Overvoltage/undervoltage, overcurrent, short circuit, overheating, feedback loss, encoder emulation fault

Supports torque/speed/position control modes (switchable via parameter)

Application Scenarios

Heavy-duty CNC machine tools and large machining centers (high precision analog control)

High-power handling robots and heavy automated lines (noise immunity in harsh environments)

Retrofits of legacy systems requiring high-resolution analog command + encoder simulation

Metallurgical, forging, and stamping equipment (continuous high torque operation)

High-power servo systems with analog host controllers (16-bit resolution requirement)

Usage and Maintenance

Mount vertically; ensure cabinet ventilation (0–45 °C ambient, ≥100 m³/h airflow)

Wire DC bus (6 mm²), 24 V control (1.5 mm²), motor (10 mm²), feedback (shielded twisted pair), and analog command (shielded) cables

Configure parameters via IndraWorks (including encoder emulation resolution, analog scaling)

Clean fan/heat sink every 6 months; inspect terminals and cables periodically

Calibrate control loops and analog offset every 2 years
