Just started a new job where the control systems are outdated compared to what I'm used to with Allen Bradley and Siemens. I'm interested in upgrading a pair of Superior Slo-Syn Drives to kollmorgen akd servo drives, but my boss wants to stick with the existing GE 90-30 IC69APU301 PLC. I have the manual for the PLC, but I'm having trouble understanding its role in the system. It appears to store the drive program, but I would appreciate an experienced perspective on how to approach programming it to integrate the new servo drives. While the wiring seems straightforward for the swap, I need guidance on transferring the drive program seamlessly.
The module has the ability to both run pre-programmed functions and follow specific commands for movement. It generates a -10 volt to +10 volt DC analog speed reference and interprets signals from an encoder for feedback. To run a pre-programmed function, the PLC activates a specific %Q output bit linked to the APU301 module. For a direct movement command, the PLC sends a command code and relevant data to the %AQ analog output addresses associated with the module. If your company allows, share the PLC program here and I can help identify the logic controlling the current servo operation. If confidentiality is a concern, reach out to me privately for my email address to send the program directly.
I've had similar experiences with the GE 90-30 PLCs in a previous role. In essence, the PLC is indeed the 'brains' of the operation, it stores and executes the drive programs. When thinking about integrating the Kollmorgen AKD servo drives, you will need to program the PLC to manage the drive parameters, inputs/outputs, and communication with the new drives. While the wiring might seem straightforward, remember to carefully examine the compatibility between the new servo drive and the existing PLC. Be ready for situations where you might need to re-write a chunk of the drive programming. From what I know, Kollmorgen provides some pretty solid tech support and resources that could simplify the process. I’d say take a closer look at the specifics of the drives, their control & communication protocols, and then explore how to translate those into your PLC’s programming language. Good luck with your project!
