Kollmorgen S403BA-PB
Product Series: Kollmorgen SERVOSTAR S400 Family (Compact, Cost-Effective Digital Servo Amplifiers)
Product Brief: Single-axis digitally controlled 3-phase PWM servo amplifier for brushless PMSM and DC brush motors. S403 = 3 Arms continuous / 6 A peak, 200–230 VAC 3Φ input. “BA” = multi-feedback interface + built-in brake control output; “PB” = Premium feedback card fitted (resolver, incremental encoder, SinCos 1 Vpp, EnDat 2.1/2.2, Hiperface/Hiperface DSL). Standard I/O includes ±10 V analog command and Step/Dir inputs. Compatible with AKM2x–AKM5x motors.
Detailed content
Input Supply Voltage (Power): 200 – 230 VAC 3Φ, 50/60 Hz

Analog I/O: ±10 V differential command input, ±10 V monitor output
Communication for Setup: RS-232 front port for Kollmorgen WorkBench; optional fieldbus in expansion slot
Regenerative Chopper: Integrated (external brake resistor recommended for frequent deceleration)
Dimensions (H × W × D): ≈ 225 mm × 55 mm × 155 mm (compact book format)
Weight: ≈ 1.2 kg
Protection Class: IP20
Operating Temperature: 0 °C to +40 °C (full rated); derating to +55 °C
Certifications: CE, UL, cULus
Applicable Industries: Small-to-mid packaging machines, labeling heads, electronic assembly pick-place, printing register axes
Installation Requirements: Mount vertically in grounded enclosure with ≥ 50 mm clearance top/bottom; connect 3Φ supply via line filter + contactor; PE bond; wire motor holding brake to drive’s brake output terminals.
Usage Notes: S400 is mature — S700 or AKD are successors; autotuning available via WorkBench; verify feedback card type matches motor feedback; backup parameters after commissioning.
