Kollmorgen S30361-NA-ARM9
Product Brief: Digitally controlled 3-phase PWM servo amplifier providing torque, velocity, and position control loops. S30361 = 230/400 VAC 3Φ input, 6 A continuous / 12 A peak. “NA” = No optional fieldbus card (bare analog/step-dir interface); “ARM9” reference on label indicates ARM9-based processor platform (S300 uses 32-bit RISC CPU). Interfaces via ±10 V analog command, step/direction, or master encoder follow. Supports resolver, incremental encoder, EnDat, BiSS via appropriate feedback card.
Detailed content
Input Supply Voltage: 208 – 480 VAC 3Φ (S30361 covers both 230 V and 400 V classes; check nameplate — S30361 typically 3Φ 230–480 VAC)
DC Bus Voltage (Nominal): ~310–565 VDC (input-dependent)
Continuous Output Current (RMS): 6.0 A
Peak Output Current (RMS, 3 s): 12.0 A
Control Logic Supply: +24 V DC (18–30 VDC), isolated
Control Modes: Torque, Velocity, Position (via ±10 V cmd or Step/Dir or Encoder Follower)
Loop Bandwidth: Velocity loop > 1 kHz; torque loop update 62.5 µs (typical S300)
Supported Feedback (with appropriate card): Resolver (std on many S30361-NA), Incremental Encoder (TTL/Line Driver up to 4 MHz), EnDat 2.1/2.2, BiSS-C, SinCos 1 Vpp
Communication / I/O: 2× ±10 V analog inputs (cmd + monitor), Step/Dir inputs (differential RS-422, up to 4 MHz), 6× DI (24 V), 4× DO (24 V 100 mA open-collector), 1× relay; RS-232 for PC configuration
Fieldbus Slot: Empty (“NA” = No optional fieldbus — CANopen / Profibus / Sercos II cards available as plug-in)
Protections: Overcurrent, bus UV/OV, I²t motor thermal model, short-circuit, heatsink OT
Dimensions (H × W × D): 225 mm × 65 mm × 155 mm (typical S300 book-style)
Weight: ≈ 1.8 kg
Cooling: Natural convection (ventilated cabinet) or with small fan in high ambient
Protection Class: IP20
Operating Temperature: 0 °C to +55 °C (full rated; derating above 40 °C)
Storage Temperature: –40 °C to +85 °C
Certifications: CE, UL, cULus, TÜV
Applicable Industries: Legacy CNC machine tool axes, packaging/form-fill-seal, converting winders/unwinders, textile machinery, printing press register — wherever S300 was specified
Installation Requirements: Vertical panel mount in grounded enclosure; 3Φ supply via line filter + contactor; PE terminal; connect 24 V logic before mains; configure via Kollmorgen WorkBench (legacy version) or front keypad if fitted.
Usage Notes: S300 is legacy / mature product — successor is AKD / AKD2G; verify feedback card type matches motor feedback before first power-up; S30361-NA has no fieldbus — position commands must come from ±10 V analog or step/dir or encoder follower; external regen resistor may be required; safe torque off not present — implement via contactor if needed.
