BODE.VFTHRESH

Description

When BODE.MODE is set to 5, the firmware monitors the drive feedback velocity VL.FB. When VL.FB goes above BODE.VFTHRESH, an internal counter records the length of time VL.FB was above BODE.VFTHRESH. If the internal counter reaches BODE.VFLIMIT, Fault F133 – Instability during Autotune will be generated.

The smaller the BODE.VFLIMIT, the quicker Fault 133 will be generated when VL.FB exceeds BODE.VFTHRESH.

Example

Set BODE.VFTHRESH to 10 RPM:

-->BODE.VFTHRESH 10

Set BODE.VFLIMIT to 0.500 seconds:

-->BODE.VFLIMIT 0.5

Set BODE.MODE to 5 to enable stability detection:

-->BODE.MODE 5

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.
