I have a system in service that uses a MMI to set the speed of 12 ABB drives over a Profibus network. It incorperates the use of a timer
accumulated value to guide the digital refernce up until the timer is done and the system is at the desired speed. If the operator needs to
make speed adjustments after the ramp time has been completed the reference changes immediately, no ramp. The operator enters the ramp time
on the MMI and it goes to the timer preset, they also set the speed, it scales the max digital reference. Any suggestions.
