Application-Specific FAQ
Q: Is the S403AM-CA compatible with third-party servo motors?
A: Yes. The SERVOSTAR 400 supports any resolver-based or incremental encoder motor. Motor data can be entered manually via WorkBench software or selected from the built-in motor database.
Q: Can this drive operate in a multi-axis synchronized system?
A: Yes. Via CANopen or PROFIBUS, multiple SERVOSTAR units can be coordinated by a master PLC or motion controller for electronic gearing and camming applications.
Q: What is the difference between S403AM-CA and 443M-C?
A: These are dual part-number designations for the same unit — S403AM-CA is the KOLLMORGEN catalog number while 443M-C is the legacy/OEM model code. Both refer to the identical hardware.
Q: Does this unit include the STO safety function?
A: The “-CA” suffix denotes the variant with integrated Safe Torque Off (STO), rated SIL 2 / PLd, eliminating the need for an external safety relay in most machine safety architectures.
Q: What software is required for commissioning?
A: KOLLMORGEN WorkBench (free download from kollmorgen.com) connects via RS-232/RS-485 and provides auto-tuning, oscilloscope, and parameter management functions.
