text: <s>[INST] Kinetix 5700 to 5500 migration Hi I have a requirement to migrate kinetix 5700 drives onto the 5500 platform, initially it looks pretty straight forward but the 5700 drives have a configurable input setup as an external enable, unfortunately this enable input is not available on the 5500 drives. Both models of drives are mounted as a block but 5700 drives are dual modules and 5500 are single am i missing anything regarding 5500 features? can i disable an individual drive from an electrical signal? is there an example where disabling using a configurable input would be advantageous or is it generally a legacy thing is it to make it easier to disable a single axis of a dual module? As i am using a MSO/MSF within the program i can still enable/disable the drive from the software so i still have control and the STO handles the safety side i would be interested to know the general opinion Thanks Andy [/INST] EDIT: modified text better highlighted to avoid confusion -FL Hello Fentiman Moving from K5700 to K5500 is not a very common move :) there is some important differences . K5700 needs a Power supply , where K5500 do not , it's more a stand alone drive with some DC bus sharing capability. And K5500 is a single axes drive. Kinetix 5500 Servo Drives User Manual (rockwellautomation.com) K5500 do not support (for the most important topic): MP Motors , only VP motors are supported EDIT: MP are supported with a converter Kit No advanced safety feature , Only wired STO or Networked depending of the Version. Do not support the same advanced tuning features K5500 do not have an auxiliary encoder input Support 2 digital inputs (4 for the K5700) Regarding your question : can i disable an individual drive from an electrical signal? you can Enable or Disable the drive with the instruction MSO or MSF . as you said the STO can be also used. Why do you need a hard wire Enable ? If you need MP motor control , look also at the K5300 drive regards \\n </s>
