Product Introduction
Legacy servo drives are the kind of component that keeps running for fifteen years — until the day they do not. The Kollmorgen CB06560 (PRD-B040SAIB-62) is a single-axis servo amplifier from Kollmorgen’s pre-KED product era, delivering 6 A/phase continuous output from a 115/230 VAC input. It is not part of the newer KED Essentials line with EtherCAT and PROFINET; it belongs to the older generation of Kollmorgen amplifiers that rely on analog/digital I/O and parameter-set configuration.
This drive is found in CNC machines, packaging lines, printing presses, and precision positioning systems where a Kollmorgen servomotor is already installed. Its 6 A/phase continuous rating and dual-voltage input make it adaptable to both single-phase and three-phase panel wiring. For procurement, the critical diligence items are parameter-set verification and feedback compatibility — a CB06560 with the wrong motor parameter file or feedback scaling will not simply “tune itself in.”
QA/QC Transparency SOP
- Intake & Origin Verification — Confirm Kollmorgen branding, CB06560 model, PRD-B040SAIB-62 assembly number, serial number, and Type B designation. Photograph all labels. Reject units with burnt components, swollen capacitors, or damaged terminal blocks.
- Live Functional Testing — Power on a test bench with a compatible Kollmorgen servomotor and proper load. Verify boot sequence, front-panel display, fault-free status, and response to analog/digital commands. Exercise current, velocity, and position modes if the test setup supports them.
- Electrical Parameter Tests — Measure input current draw at no-load and under load. Check output phase balance, DC bus voltage, and regeneration circuit behavior during deceleration. Flag any phase imbalance or excessive bus ripple.
- Parameter/Firmware Verification — Read the installed parameter set, motor type code, feedback scaling, and fault history. Archive the full parameter dump. Do not overwrite parameters without a verified backup from the end user’s machine.
- Final QC & Anti-Static Packaging — Seal in ESD bags with desiccant. Include test summary, parameter readout, fault history, and label photos. No generic “tested OK” sticker — every unit ships with logged data.
Field Engineer Gotchas
- Wrong Parameter Set — The CB06560 stores motor-specific parameters (current loop gains, feedback scaling, thermal model). Loading the wrong parameter set can cause oscillation, overheating, or fault trips. Fix: Export the existing parameter set before removing the old drive. Warning: Do not guess the motor code — match it exactly.
- Regeneration Circuit Failure — This drive has a built-in regeneration resistor. A failed regen circuit will trip during deceleration or stopping, not during acceleration. Fix: Test deceleration under load on the bench. War story: A packaging line kept faulting only on stop — the built-in regen resistor had gone open. The drive ran fine until it needed to dump energy.
- Input Phase Configuration Mismatch — The drive accepts both 1-phase and 3-phase 230 VAC input, but the input current rating changes (10 A vs 7.8 A). Fix: Verify the panel wiring matches the installed configuration. Warning: Undersized input wiring on 1-phase operation can cause nuisance trips.
- Feedback Cable Integrity — Encoder or resolver cables on legacy Kollmorgen systems are a common failure point. A marginal cable can cause intermittent position faults that look like drive problems. Fix: Check shield continuity, pin seating, and cable routing away from power conductors. Blunt advice: Swap the cable before swapping the drive if the fault is intermittent.
- Capacitor Aging — Legacy drives sitting in surplus storage for years can have dried or weakened DC bus capacitors. Fix: Measure ESR and capacitance if the unit has been in storage over five years. Warning: A weak bus capacitor causes undervoltage faults and erratic behavior under load.

Application Scenarios
- CNC machine servo axis replacement — A failed on a milling machine axis must be replaced with a unit carrying the correct motor parameter set and feedback scaling to avoid re-tuning the entire axis.
- Packaging line servo drive swap — The drive controls a registration axis on a form-fill-seal machine. Deceleration faults point to the regen circuit rather than the motor.
- Printing press registration control — The drives a web tension or registration roller, requiring stable velocity control and fast response to registration marks.
- Precision positioning test fixture — A lab fixture uses a Kollmorgen servomotor with the for repeatable positioning; parameter-set integrity is critical for repeatability.
FAQ
A: No. The CB06550 and are different models in Kollmorgen’s legacy servo drive family. Do not substitute one for the other without verifying electrical ratings and parameter compatibility.
Q: What is the PRD-B040SAIB-62 number?
A: It is the assembly or configuration part number associated with the drive. Always confirm both numbers on the nameplate before purchasing.
Q: Can this drive run on single-phase 230 VAC?
A: Yes. The input supports 115/230 VAC in both 1-phase and 3-phase configurations. Input current is 10 A at 115 VAC and 7.8 A at 230 VAC per phase.
Q: Does it support EtherCAT or PROFINET?
A: No. Those protocols belong to Kollmorgen’s newer KED Essentials line. The is a legacy amplifier using analog/digital I/O and parameter-set configuration.
Q: What software configures it?
A: Configuration is done through Kollmorgen’s legacy software toolset (parameter set download). The exact software version depends on the drive’s firmware revision. Verify with the OEM documentation.
Q: Is this drive still in production?
A: No. The is a discontinued legacy product. Only surplus or refurbished stock is available.
Q: What motor types does it support?
A: It supports Kollmorgen servomotors compatible with the legacy amplifier family. The specific motor must be matched via the parameter set. Verify motor compatibility with the OEM documentation before deployment.
