Kollmorgen S61401-PB
Product Introduction:
These are S200-series single-axis servo amplifiers configured with the “PB” (Panel Bus / Proprietary Kollmorgen bus) communication option rather than SynqNet. They share the same digital architecture, current-loop performance, and feedback capabilities as the S20660-SRS but are intended for standalone or legacy Kollmorgen multiaxis systems using the Panel Bus interface.

Model Differences:
-
S61001-PB-550: Approx. 1.0 A RMS continuous / ~3 A peak — for very small AKM or Goldline motors
-
S61401-PB: Approx. 1.5–4.0 A RMS continuous depending on exact sub-variant (typically 4 A / 12 A peak in the S200 4A class)
Key Specifications (common to S200 PB models):
-
Main Power: 120/240 VAC (90–264 VAC) or 20–90 VDC (model-dependent)
-
Control Supply: 24 VDC (18–32 VDC)
-
Current Loop BW: 3–5 kHz
-
Velocity Loop BW: 800 Hz
-
Feedback: SFD, EnDat 2.2, BiSS, Hiperface, resolver, incremental encoder
-
Interface: Panel Bus (PB) for command reference from a master controller or indexer; RS-232 for setup
-
I/O: Optically isolated digital inputs/outputs, analog reference (±10 V)
-
Protection: Over-current, over-voltage, thermal, short-circuit
-
Mounting: Panel mount inside enclosure, IP20
-
Certifications: UL 508C, CE, cULus
Application & Notes:
-
Typically paired with Kollmorgen AKM or Goldline B/M series servomotors
-
Commissioned via Kollmorgen WorkBench using RS-232; motor parameters auto-loaded from SFD-equipped motors
-
When retrofitting, verify firmware revision compatibility with the host indexer or PLC
