AXIS#.VL.THRESH

Description

AXIS#.VL.THRESH sets the user over-speed fault threshold. This threshold becomes the overall over-speed fault threshold (AXIS#.VL.VFTHRESH) if it is less than the motor speed threshold (1.2 x AXIS#.MOTOR.VMAX), and for AXIS#.MOTOR.TYPE = 6 if it is less than the motor back EMF overspeed threshold ((1.02 x 1000 x VBUS.OVFTHRESH) / (AXIS#.MOTOR.KE x sqrt(2))).

The value is considered an absolute value, hence it applies for both negative and positive velocities.

Example

AXIS#.VL.THRESH is set to 600 rpm. A velocity (AXIS#.VL.FB ) of 700 rpm will generate an over speed fault.

Units

Rotary: RPMClosed "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, RPS, deg/s, (custom units)/s, rad/s

See Velocity Units for details.

Range

Depends on units. See Velocity Range for details.

Fieldbus Information

EtherCATClosed ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs CoE and CANopen
