WS.VTHRESH

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 F478n478 is generated. Setting WS.VTHRESH to zero disables this feature. For Mode 1, WS.VTHRESH is only used after the initial phase-finding.

Fieldbus Information

If your drive type is listed as supported but no index, address, or instance number is listed, then this parameter is accessible through WorkBench, but not over your fieldbus type. For information on SynqNet parameters see SynqNet Supported Parameters.
