AXIS#.BODE.VFTHRESH

Description

When AXIS#.BODE.MODE is set to 5, the firmware monitors the drive feedback velocity AXIS#.VL.FB. When AXIS#.VL.FB goes above AXIS#.BODE.VFTHRESH, an internal counter records the length of time AXIS#.VL.FB was above AXIS#.BODE.VFTHRESH. If the internal counter reaches AXIS#.BODE.VFLIMIT, Fault F6003 – Instability during Autotune will be generated.

The smaller AXIS#.BODE.VFLIMIT, the quicker Fault F6003 will be generated when AXIS#.VL.FB exceeds AXIS#.BODE.VFLIMIT.

Example

Code

Set AXIS1.BODE.VFTHRESH to 10 RPM"Revolutions per minute" Is a unit of frequency of rotation: the number of full rotations completed in one minute around a fixed axis. It is used as a measure of rotational speed of a mechanical component:

--> AXIS1.BODE.VFTHRESH 10

Set AXIS1.BODE.VFLIMIT to 0.500 seconds:

--> AXIS1.BODE.VFLIMIT 0.5

Set AXIS1.BODE.MODE to 5 to enable stability detection:

--> AXIS1.BODE.MODE 5
