Parameter setting examples – ACS850
Speed control using the CiA 402 velocity mode (vl)
This example shows how to configure a speed control application 
that uses the velocity mode (vl) of the CiA 402 profile. 
When configuring the master, you need to map the following 
objects to the transmit and receive PDOs. For an example, see 
section Mapping objects required for controlling the drive on 
page 66.
The table below gives the recommended drive parameter settings.
