Kollmorgen CB06561 PRD-B040SSLZ-62 | SERVOSTAR 300 Series Servo Drive

Description

Key Technical Specifications

Product Introduction

The Kollmorgen CB06561, product number PRD-B040SSLZ-62, is a digital servo drive from the SERVOSTAR 300 family. It accepts single- or three-phase 115/230 VAC input and delivers a controlled 230 VAC, 6 A continuous output to drive permanent-magnet synchronous servo motors. The drive provides closed-loop position, speed, and torque control, making it suitable for applications where motion accuracy, repeatability, and dynamic response matter more than raw power.

This unit is typically found in older packaging machines, printing presses, CNC axes, and robotic stations where Kollmorgen motion systems were specified as the OEM drive platform. The “SSLZ” suffix and firmware 7.3.3 indicate a specific configuration variant, so replacement units must be matched carefully. Because this is a legacy product, commissioning depends heavily on the existing motor, feedback type, and archived parameter set — not just the part number.

QA/QC Transparency SOP

1. Nameplate Verification — Confirm CB06561 and PRD-B040SSLZ-62 on the drive label. Record firmware version, serial number, and hardware revision. Reject units with mismatched labels or missing firmware data.
2. Visual & Mechanical Inspection — Check for burned components, swollen capacitors, corroded terminals, or damaged connectors. Verify that power, motor, feedback, and communication terminals are intact.
3. Power-Up Test — Apply rated input voltage through an isolation transformer or variac. Confirm normal power-up sequence, absence of immediate fault codes, and stable DC bus voltage.
4. Motor Run Test — Connect a compatible PMSM servo motor with correct feedback. Run in velocity mode at low speed, then step through rated speed. Monitor current balance, torque ripple, and fault status.
5. Protection Verification — Simulate or verify overcurrent, overvoltage, and overtemperature protection responses. Confirm that fault latching and reset behavior are normal.
6. Parameter Backup — Upload existing parameters before any changes. If the drive is blank, load parameters only from a verified backup matched to the motor and application.
7. Final Packaging — Document test results, firmware version, and parameter checksum. Pack with ESD protection and include a one-page test record.

Field Engineer Gotchas

• Variant Suffix Matters — PRD-B040SSLZ-62 is not automatically interchangeable with PRD-B040SAIB-62, PRD-B040SSIB-63, or other CB065xx variants. Communication options, firmware, and I/O may differ. Solution: Match the full product number, not just “CB06561.”
• 1-Phase vs. 3-Phase Input Derating — Running a three-phase-rated drive on single-phase input typically requires current derating and may increase DC bus ripple. Solution: Check the nameplate input current rating and verify that the upstream breaker, contactor, and supply wiring are sized correctly.
• Motor/Feedback Mismatch — The drive must be configured for the correct motor type, encoder resolution, and feedback protocol. A wrong feedback setting can cause runaway, oscillation, or immediate faults. Solution: Restore the original parameter set or re-identify the motor before enabling closed-loop control.
• Legacy Firmware Limitations — Firmware 7.3.3 may not support newer configuration tools or certain fieldbus options. Solution: Use the original Kollmorgen configuration software compatible with SERVOSTAR 300 firmware 7.x. Do not assume AKD WorkBench compatibility.
• DC Bus Capacitor Aging — Legacy drives that have sat in storage for years can suffer from dried electrolytic capacitors. Solution: Reform the DC bus capacitors with a controlled voltage ramp before full-load operation.

Application Scenarios

• Legacy packaging machine axis replacement — A form-fill-seal machine loses its original servo drive. The CB06561 is replaced with a verified PRD-B040SSLZ-62, parameters are restored from backup, and the axis returns to service without mechanical changes.
• Printing press register control — The drive controls a print cylinder axis where position accuracy directly affects registration. The existing motor and encoder are retained, and only the drive is swapped.
• CNC retrofit spare pool — A maintenance team keeps a tested CB06561 as a cold spare for an older CNC retrofit that still runs Kollmorgen SERVOSTAR drives.
• Robotics joint drive failure — A small industrial robot axis faults on overcurrent. After ruling out motor and cable issues, the drive is replaced with a tested and the original parameter file.

FAQ

A: is the order code; is the product number. They refer to the same drive, but the full product number should always be verified because suffix changes can indicate different options.

A: Not without verification. The suffixes indicate different configurations, possibly including communication interfaces, firmware, or I/O options. Treat them as non-interchangeable until the nameplate and parameters are confirmed.

Q: What motors does this drive support?
A: It is designed for permanent-magnet synchronous servo motors compatible with the SERVOSTAR 300 family. The motor, encoder, and parameter set must all be matched to the drive configuration.

Q: Can this drive run on single-phase 230 VAC?
A: The nameplate indicates 1- or 3-phase input capability, but single-phase operation may require derating. Verify the input current rating on the actual unit before installation.

Q: What software is used to configure it?
A: Legacy Kollmorgen SERVOSTAR 300 configuration software compatible with firmware 7.x. Newer AKD tools may not support this drive.

Q: Is this drive still in production?
A: The SERVOSTAR 300 family is considered legacy. Units in circulation are typically surplus, refurbished, or retained as maintenance spares.

Q: What is the output current rating?
A: 6 A continuous output at 230 VAC, with apparent output power in the range of approximately 1.4–2.2 kVA depending on input conditions.
