14 Quick Start-up Guide for ACS850 with Standard Control Program
You are now asked if each constant speed selector should activate one constant speed.
No: Constant speeds 1...7 are activated by the sources selected by parameters 26.02,
26.03 and 26.04 as follows:

Yes: Constant speeds 1...3 are activated by the sources selected by parameters 26.02,
26.03 and 26.04 respectively.
Set the constant speed selector sources.
Enter the constant speeds.
Select the source of the speed reference signal.
Define the absolute minimum limit for the speed
reference. This limit applies for both the positive and
negative ranges.
Define the speed scaling used for the acceleration/
deceleration times. Define the acceleration/
deceleration times.
The diagram below shows the effect of parameter
19.01 Speed scaling on the acceleration/
deceleration times.
