text: <s>[INST] Kinetix 300 Vertical Brake Summary: Need information on wiring of control and timing for vertical application with holding brake We have a vertical application. The servo motor has a holding brake. An emergency turn off requires the following sequence (this is easy to achieve in other servos) 1. Press emergency stop 2. Signal (which one ?) to the Kinetix 300 is dropped (logic power and 3 phase is kept) 3. Kinetix brings any motion to a halt but holding torque is still on. 4. The Kinetix brake release output turns off to set the holding brake, holding power is maintained 5. A set time later (to allow the holding brake to fully engage) the holding power is released and the drive is disabled. External safety relay timed contacts will - after this action - remove power from the holding brake circuit and turn off the safety inputs to the Kinetix. (This wiring is already in place) We are confused as to the wiring/settings to achieve the numbered steps. This has been fairly easy and actually spelled out in manuals on other servo systems. [/INST] The place to start is here: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/2097-um001_-en-p.pdf Page 93 shows the two parameters you would need to set (651 and 652) for time delays regarding the brake output of the K300 drive. You will need to coordinate the two parameters with your external safety relay timed contacts to make this work. It's not a control scheme I would be very happy with - the K300 is a very simplistic servo. I would take complete control of the brake via external logic (sounds like you already have it), and not do any brake control within the K300 at all. \\n </s>
