Description
This parameter defines the maximum allowed velocity that occurs while commutation finding is
active. This supervision runs in real time, but only while wake and shake is active (WS.STATE
2 or greater, for Mode 0). If at any time while wake and shake is running a velocity higher than
this value is detected, fault F478 is generated. Setting WS.VTHRESH to zero disables this fea-
ture. For Mode 1, WS.VTHRESH is only used after the initial phase-finding.
