Functional Features: Full three‑loop digital closed‑loop motion control; motor auto‑recognition and auto‑tuning function; cogging‑torque suppression; electronic cam, electronic gear and master‑slave synchronization; encoder emulation output; comprehensive fault diagnosis function; MMC card for parameter backup and firmware update; STO hardware safety function; multi‑level hardware protection for over‑current, bus over‑voltage, bus under‑voltage, over‑temperature and feedback‑signal loss; front‑panel LED status indication.
Application Scenarios: Heavy‑duty packaging machinery, large‑format printing equipment, metal‑processing machine‑tool main‑and‑feed axes, material‑handling heavy‑load axes, industrial robotic joint axes.
Performance Parameters: Current‑loop update 62.5 μs; velocity‑loop update 125 μs; position‑loop update 250 μs; I²T thermal overload protection; 200 % short‑term overload capacity; fast fault response and safe‑state switch.
Material Composition: Die‑cast aluminum alloy housing; high‑power IGBT power modules; gold‑plated industrial‑grade connectors; flame‑retardant high‑voltage PCB; metal heat‑sink fins; built‑in cooling fan; LED indicator array; MMC memory‑card socket.
Structural Features: Large‑size book‑style cabinet‑mount housing; front‑panel LED status indicators; front‑side USB service port and MMC slot; lateral EtherCAT and CANopen communication connectors; rear‑side high‑current power terminals, motor connector, feedback and I/O terminals; internal forced‑air fan cooling; vertical cabinet‑mount installation.
Working Principle: Three‑phase mains power is rectified to DC‑bus voltage. Power inverter generates three‑phase AC current to drive servo motor. Feedback signals are converted to digital values for high‑speed three‑loop algorithm computation. Motion commands are received via EtherCAT or CANopen fieldbus. Hardware safety circuit executes STO safe‑torque‑off function. Monitoring circuits detect operating parameters and trigger power‑stage shutdown under fault conditions.
Installation Requirements: Vertically mount inside IP20 control cabinet; keep 35 mm upper‑lower ventilation clearance and 20 mm left‑right clearance; high‑power motor power cables must use shielded heavy‑duty cables; power wiring and signal wiring run in separate cable ducts; protective‑earth terminal must connect reliably to cabinet grounding bar; STO safety‑circuit wiring complies with IEC‑61508 safety requirements.
Usage Notes: Do not hot‑swap wiring terminals while unit is powered‑on; DC‑bus holds high‑voltage energy after power‑off, allow sufficient discharge‑time before maintenance; keep fan and heat‑sink free of dust blockage; ambient temperature shall not exceed 45 °C; spare‑part replacement must match hardware revision and firmware version.
