Material Composition

• Housing: Powder‑coated aluminum alloy metal casing
• Power unit: IGBT power module, high‑voltage DC‑bus capacitor bank
• Control board: Multilayer PCB, safety logic chip, encoder signal processing circuit
• Terminals: Screw‑clamp high‑current power terminals

Structural Characteristics Vertical wall‑mount metal housing. High‑power DC‑bus terminals, motor‑output terminals and signal terminals located at bottom area. Front‑side status LED indicators, expansion‑module slots on upper section. Internal forced convection air cooling.

Working Principle High‑voltage DC‑bus power is converted to three‑phase variable‑frequency variable‑voltage AC output via IGBT power stage to drive servo motors. The control unit processes encoder feedback signals to realize closed‑loop speed, position and torque control. Integrated safety logic implements SafeMOTION safety‑related motion functions.

Installation Requirements

• Vertical wall‑mount installation only; horizontal‑standing mounting is prohibited
• Maintain specified upper‑lower‑left‑right ventilation clearance for convection cooling
• Must use matched terminal‑block sets for high‑power wiring
• Comply with power‑cable cross‑section requirements for 44 A rated current
• Ground protective‑earth terminal reliably
