Kollmorgen CE03550 Servo Drive 3 A Continuous Output

Description

Key Technical Specifications

The 3 A continuous / 9 A peak ratings, encoder characteristics, loop bandwidths, and update rates are reported specifically for CE03550 by current industrial automation reference listings.

Product Introduction

The Kollmorgen CE03550 is a SERVOSTAR CD digital AC servo drive used to regulate torque, velocity, and position in closed-loop motion systems. The model is associated with the PRD-B040EAIB-33 part number and uses encoder feedback. Available technical data identifies a 3 A rms continuous output rating, 9 A rms peak current for 0.5 seconds, 14-bit analog resolution, and a 2.5 kHz current-loop bandwidth.

For replacement work, do not select the CE03550 by model number alone. Verify the drive nameplate, motor compatibility, input voltage, feedback type, existing parameter set, and mechanical load requirements before energizing a replacement unit. This is particularly important because third-party databases contain conflicting electrical ratings for this model.

Installation & Configuration Guide

Stage 1 — Pre-Installation Preparation

Approximate time: 20–30 minutes

1. Isolate the machine from all hazardous energy sources. Apply the site’s lockout/tagout procedure before opening the servo enclosure.
2. Record the existing drive’s complete nameplate information, including CE03550, associated PRD number, serial number, voltage rating, and revision information.
3. Photograph the power, motor, feedback, I/O, and control wiring before removal.
4. Back up the existing servo parameters if the drive still communicates with the commissioning software.
5. Record motor model, encoder type, electronic gearing, acceleration/deceleration settings, current limits, and tuning parameters.
6. Confirm that the replacement unit’s actual nameplate matches the required current and voltage ratings.

⚠️ Do not rely on a supplier database alone when conflicting CE03550 specifications are shown. The physical nameplate and original machine documentation take precedence.

Stage 2 — Removing the Existing Drive

Approximate time: 15–25 minutes

1. Confirm that the DC bus and other hazardous voltages have discharged according to the manufacturer’s service procedure.
2. Label every conductor and connector before disconnecting the drive.
3. Disconnect the AC input, motor output, feedback, command, and auxiliary connections.
4. Release the drive’s mounting hardware and remove the unit without stressing adjacent wiring.
5. Inspect terminal blocks and connectors for heat damage, oxidation, loose pins, or insulation deterioration.
6. Check the motor and feedback cables before installing the replacement drive.

⚠️ Never assume an existing feedback connector can be transferred without verification. Encoder wiring errors can produce incorrect commutation or uncontrolled motor behavior.

Stage 3 — Installing the

Approximate time: 20–30 minutes

1. Verify that the replacement unit is the exact configuration required by the machine.
2. Compare the replacement nameplate with the recorded original before mounting.
3. Install the drive using the original mounting arrangement and maintain the enclosure’s required cooling clearance.
4. Reconnect AC input, motor, feedback, control, and grounding connections using the original wiring records.
5. Confirm that motor phases and feedback channels correspond to the machine’s documented configuration.
6. Restore the stored servo parameters or manually enter the machine’s documented configuration.
7. Do not copy tuning values blindly if the replacement drive, motor, feedback device, or mechanical load differs from the original setup.
8. Recheck every terminal and connector before applying power.

Stage 4 — Power-On & Testing

Approximate time: 30–60 minutes

1. Perform a final wiring and grounding inspection with the machine still disabled.
2. Energize the drive according to the machine manufacturer’s prescribed startup sequence.
3. Check the drive display and diagnostic indications for initialization or fault conditions.
4. Establish communication with the commissioning/configuration software where supported.
5. Verify feedback polarity, motor direction, encoder counts, command scaling, current limits, and enable logic.
6. Test the axis at low speed with the mechanical system in a controlled condition.
7. Confirm emergency-stop and drive-disable functions before returning the axis to production.
8. Perform a controlled dry run through the normal operating range.
9. Save the validated parameter configuration as the new maintenance backup.

⚠️ If the drive reports a feedback, overcurrent, bus-voltage, or configuration fault, stop the test rather than repeatedly resetting the fault. Check the corresponding wiring and parameter group first.

FAQ

Is a PLC module?

No. The is a Kollmorgen SERVOSTAR CD servo drive/amplifier, not a PLC I/O module. Its primary task is closed-loop servo motor control.

What part number is associated with ?

The is frequently listed together with PRD-B040EAIB-33. Several industrial automation sources identify that combination explicitly.

What is the continuous current rating?

-specific technical listings identify 3 A rms continuous output current and 9 A rms peak output current for 0.5 seconds.

Why do some websites show 6.2 A and 18.6 A?

There are conflicting third-party database entries for . One listing gives 6.2 A continuous and 18.6 A peak, while another listing gives 3 A continuous and 9 A peak.

For a replacement purchase, use the complete drive nameplate and machine documentation to resolve the discrepancy rather than assuming the higher rating applies to every unit.

Does use encoder feedback?

Yes. The technical data identifies encoder feedback, a 5 VDC encoder supply, and support for incremental encoder signals up to 12 MHz post-quadrature.

Can I install a replacement without reconfiguring the machine?

Not necessarily. Servo parameters, motor data, feedback configuration, electronic gearing, limits, tuning, and command scaling are application-specific. Back up the existing configuration before replacement whenever possible, then verify the replacement drive’s configuration before enabling the motor.

Is suitable as a universal replacement for other Kollmorgen SERVOSTAR drives?

No. Similar-looking SERVOSTAR drives can have different current ratings, feedback interfaces, voltage requirements, and parameter structures. Replacement should be based on the complete part number and application requirements, not simply the SERVOSTAR family name.
