Where do I find the parameters for the stopping ramps in Starter

Please also see the attached screenshots.

We have 2 motors on a machine that are supposed to stop at the same time - but they do not.

So I have been asked to find out why they do not stop at the same time - perhaps by comparing the stopping ramps for the 2 drives.

I am opening the drives ("Former" and "Rotor") in my starter program and it looks to me the it is an AC drive (G120) and a DC  drive (CU_DC_126) but it must still be possible too see the times for the stopping ramps - but where do I find this info for the 2 drives?

What else can make the motor not stop at the same time?

I would look to see if they are getting the stop signal at the same time. The PLC may have some delay's built in. Also, do both drives have breaking resistors? (usually on top the cabinet). The drive can only do so much breaking. The energy has to "go" some where. If not make sure it is a gentle slop to stop. If heavy inertia going down hill.... let it take even longer.

You are looking for the "list" manual for each drive. I did a search for G120 list manuals. There are several one for each CU type. here is one:
