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. 26.02 Const speed sel1
26.03 Const speed sel2
26.04 Const speed sel3
Enter the constant speeds. 26.06 Const speed1…
Select the source of the speed reference signal. 21.01 Speed ref1 sel
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.
Note: Acceleration/deceleration times may be
automatically extended by the existing torque limits.
