  • Associated product(s)

QUESTION:  
Can the closed-loop control module, order number 6ES5252-3AA21, be substituted by closed-loop control module 6ES5252-3AA13? 
What is the difference between the two modules?

ANSWER:  
Closed-loop control module 6ES5252-3AA21 is a special version of the IP252 modules with a special firmware for the 12MHz applications and cannot be substituted by closed-loop control module 6ES5252-3AA13. 
Module 6ES5252-3AA21 does not have the drive and standard closed-loop controller structure of module 6ES5252-3AA13 and was developed specially for fast closed-loop controller tasks in synthetic materials technology and for hydraulic drives.

Module 6ES5252-3AA21 can still be ordered as a replacement module at:
