- Apparent Power Rating: 1.8 kVA at 115 VAC, 2.8 kVA at 230 VAC
- Auxiliary Logic Supply: 22‑27 VDC
- Control Signal Level: ±10 V analog set‑point, open‑collector digital I/O
- Cooling Method: Natural convection via integrated aluminum heat sink
- Protection Class: IP20
- Weight: 3.2 kg
- Functional Features
- Hybrid analog front‑end plus digital fault‑monitoring logic
- Supports velocity mode, torque mode and external position step‑direction reference mode
- Built‑in 12‑bit analog output for real‑time torque or velocity monitoring
- Multi‑level hardware protection: over‑current, over‑voltage, under‑voltage, motor short‑circuit, heat‑sink over‑temperature, motor wiring loss detection
- Open‑collector fault relay output with 3 ms fault closing response time
- On‑board potentiometers for manual gain adjustment of current‑loop and velocity‑loop parameters
- No fieldbus interface, motion command relies on analog voltage or step‑direction pulse signals
- Dynamic brake circuit integrated for rapid motor deceleration
- Application Scenarios: Legacy production‑line equipment retrofitting, printing machinery, textile old‑model processing machines, special‑purpose test stands, conveyor auxiliary servo axes, equipment upgrade projects retaining original host controller hardware
- Performance Parameters: Velocity‑loop bandwidth up to 450 Hz; current‑loop hardware response time below 12 µs; analog command resolution reaches 4.9 mV; supports motor tachometer and incremental encoder feedback sources
- Material Composition: Cast anodized aluminum heat‑sink base, cold‑rolled steel enclosure shell, FR‑4 grade double‑sided printed circuit boards, bipolar power transistors, wound power electrolytic capacitors, plastic barrier terminal blocks, variable‑resistor trimming potentiometers
- Structural Characteristics: Horizontal panel‑mount metal housing; power circuit area and signal circuit area are physically partitioned inside enclosure; barrier screw terminals for power and logic wiring; D‑Sub connector for encoder and tachometer feedback; top‑surface potentiometer access cover for on‑site gain tuning; external mounting holes for cabinet panel installation.
- Working Principle: Mains AC voltage is rectified into DC bus voltage; analog error amplifier compares external command signal with motor velocity or torque feedback signal; power output stage generates adjustable magnitude DC current to drive brush‑type permanent‑magnet servo motor; tachometer or incremental encoder delivers real‑time motor operating feedback; hardware fault detection circuit continuously monitors power‑stage temperature, bus voltage and output current, triggers fault relay output and cuts power‑stage output upon fault occurrence.
- Installation Requirements: Mount horizontally on cabinet metal panel; maintain free surrounding space for natural convection cooling; avoid stacking heat‑generating devices directly adjacent to this unit; protective earth terminal must connect to cabinet protective ground; ambient operating temperature range 0‑40 °C; altitude below 1000 m without performance derating.
- Usage Notes: Do not apply power before finishing protective‑earth connection; avoid operating without motor load connected; adjust gain potentiometers gradually to prevent mechanical oscillation; electrolytic capacitors require reforming procedure if storage duration exceeds 12 months; prevent conductive dust and moisture condensation inside enclosure; do not operate with enclosure cover removed; verify feedback wiring correctness before power‑on.
