Core Functions

Three‑loop control (current/speed/position) for high precision

DA02 enhanced analog interface: improved noise immunity, extra I/O vs DA01

Internal cooling saves cabinet space for dense multi‑axis layouts

Comprehensive protection: over/undervoltage, overcurrent, short circuit, overheat, feedback loss

Torque / speed / position control modes

Modular design: fieldbus/serial modules can be retrofitted

Application Scenarios

Medium‑to‑high power CNC machine axes

Textile, printing, packaging machinery

Multi‑axis handling robots and assembly lines

Analog‑based automation systems needing extra I/O

Retrofits of legacy analog servo systems

Usage and Maintenance

Ensure adequate cabinet airflow for cooling

Keep ambient ≤45 °C to avoid derating

Complete power/feedback/analog wiring before power‑on

Set parameters via IndraWorks according to application

Clean air ducts/heatsinks every 6 months; check terminals

Calibrate loops/feedback annually
