Product Introduction
Kollmorgen CP320260 Overview
The Kollmorgen CP320260 is a digital servo amplifier from the Servostar SP family designed for demanding industrial motion control applications. It provides the electrical interface between a machine controller and servo motor, managing motor current generation, velocity regulation, and position control through closed-loop feedback.
The Kollmorgen CP320260 delivers 20 A RMS continuous output current per phase and supports short-duration peak output levels of up to 40 A RMS per phase. This capability allows the drive to handle acceleration demands, dynamic load changes, and positioning cycles commonly found in automated machinery.
The Kollmorgen CP320260 uses digital control technology with space vector PWM current regulation to maintain accurate motor torque control. The drive supports multiple feedback technologies, including resolver, SSI, sine/cosine encoder, and ROD-426 feedback systems, allowing integration with different servo motor configurations.
The Kollmorgen CP320260 is commonly installed in CNC equipment, robotics systems, packaging machinery, semiconductor equipment, and automated production lines. It is not a standalone controller; it requires a compatible motion controller or PLC system to provide command signals and application logic.
Before replacement, engineers should verify motor ratings, feedback device type, parameter backup, drive firmware, and machine controller configuration. Servo drives are highly application-specific, and incorrect motor data or tuning parameters can result in poor performance even when the replacement hardware is electrically compatible.

Application Scenarios & Field Pitfalls (The Engineer’s Perspective)
Engineering Pain Point
A machine axis experiences position errors, servo faults, excessive following error, or unexpected motor behavior. The drive may be blamed first, but many servo problems originate from feedback, tuning, mechanical load, or parameter issues.
Recommended troubleshooting steps:
- Check drive fault history
- Verify motor feedback wiring
- Confirm encoder/resolver compatibility
- Check motor identification parameters
- Review acceleration and load settings
- Inspect mechanical coupling and backlash
The manages motor power and control loops, but the complete motion system determines final performance.
Typical Applications
CNC Machine Systems
Used for:
- Axis positioning
- Spindle-related motion systems
- High-accuracy machining equipment
Robotics and Automation
Applied in:
- Robotic joints
- Pick-and-place systems
- Automated assembly equipment
Packaging Machinery
Used for:
- Indexing mechanisms
- Conveyor synchronization
- Servo-driven actuators
Manufacturing Equipment
Applied in:
- Material handling systems
- Precision inspection machines
- Production automation lines
Technical Pitfalls to Avoid
1. Verify Motor and Feedback Compatibility
Before replacement, confirm:
- Servo motor model
- Rated current
- Feedback type
- Encoder/resolver wiring
A drive may power up correctly while failing to operate due to incorrect feedback configuration.
2. Restore Drive Parameters
Save and verify:
- Motor parameters
- Current limits
- Velocity loop settings
- Position loop tuning
- Application-specific settings
Servo performance depends heavily on correct parameter configuration.
3. Check Power Supply Conditions
Inspect:
- Three-phase input voltage
- DC bus condition
- Grounding
- Protective devices
Unstable supply conditions can create repeated drive faults.
4. Evaluate Mechanical System Condition
Servo alarms may result from:
- Excessive mechanical load
- Damaged bearings
- Coupling problems
- Incorrect alignment
Replacing the amplifier alone may not correct mechanical-related faults.
