If the Kv factor is too large, the system will oscillate about the pre-controlled speed set value.
The size of the Kv factor is normally the same as the Kv factor for operation with servo lag
Depending on the dynamic characteristics of the machine it may also be higher (see section
"Commissioning and start-up procedure").
