Performance Parameters The drive delivers the SERVOSTAR CD family’s characteristic 800 Hz speed loop bandwidth with enhanced power capability. The 6.5A continuous rating enables driving motors up to approximately 2.5 kW continuous power at 230 VAC or 5 kW at 480 VAC. Peak current of 19.5A provides 3:1 overload capability for acceleration and transient load conditions. The drive maintains current loop bandwidth of 3-5 kHz across the full operating range. Position loop resolution is 32-bit with feedforward compensation for tracking accuracy.
Material Composition The drive features a robust aluminum enclosure with heavy-duty powder coating for industrial environments. Power semiconductors are mounted on direct-bonded copper (DBC) ceramic substrates for optimal thermal and electrical performance. DC bus capacitors are high-grade electrolytic types with extended life ratings. The control PCB uses 6-layer construction with separate power and ground planes for noise immunity. Internal wiring employs high-temperature silicone-insulated conductors. Cooling fan (if equipped) uses ball-bearing motors with sealed housings for long life.
Structural Characteristics The drive has a larger footprint than lower-current models, reflecting the increased power handling capacity. The enclosure features integrated heat sink fins on three sides for maximum heat dissipation area. Front panel includes a 7-segment display for fault codes and status indication, supplementing the standard LED indicators. Terminal blocks are higher-capacity types rated for the increased wire gauges required for 6.5A service. Internal layout separates power and control sections with a metal shield barrier. The base includes both DIN rail clip and direct panel mounting options.
