Application Scenarios
A metal fabrication shop was experiencing frequent servo faults and positioning inaccuracies on a legacy CNC lathe that had been in operation for over 15 years.The machine used the ABB ACS600 system with 1263121 servo drives.
After inspecting the system,engineers determined that the original drive modules were degrading due to aging capacitors and thermal stress.
By replacing the faulty 1263121 modules with tested and refurbished units,and performing a full system calibration:
Servo performance was restored to near-original levels
Positioning errors were reduced by 90%
Machine uptime improved significantly
Costly full system replacement was avoided
Result:The shop extended the life of their legacy CNC machine by several years,proving the ABB 1263121’s continued relevance in older but mission-critical automation systems.
Parameter Table
Main Parameters Value/Description
Product Model 12-63121/1263121

Technical Principles and Value
Analog Control Architecture:Unlike modern digital drives,the 1263121 uses analog signals for speed and position control—making it compatible with older CNC and motion systems.
Encoder Feedback Loop:Supports incremental encoders for closed-loop position control.
High Reliability in Legacy Systems:Despite being a legacy product,it remains essential for maintaining older ABB ACS600-based machines.
Compatibility with Analog Controllers:Works with older PLCs and motion controllers that output±10V analog signals.
Robust Industrial Build:Designed for industrial environments with ruggedized components and long life expectancy when maintained.
While modern systems have moved toward digital fieldbus communication(e.g.,EtherCAT,CANopen),the 1263121 still provides cost-effective motion control in applications where upgrading the entire system is not feasible.
Application Cases and Industry Value
Case Study:Retrofit of Legacy Injection Molding Machine
An injection molding facility had a long-operating press controlled by an ABB ACS600 system using 1263121 servo drives.The machine was still functional but had become unreliable due to aging drives.
Instead of replacing the entire control system,the facility opted to:
Replace all 1263121 drives with tested refurbished units
Upgrade the encoder cables and motor brushes
Re-calibrate the axes using analog signal tuning
Result:The retrofit extended the machine’s operational life by at least 5 years,with improved reliability and consistent performance—demonstrating how the 1263121 remains valuable in maintaining legacy automation infrastructure.
