AXIS#.VL.THRESH

Description

AXIS#.VL.THRESH sets the user overspeed fault threshold. This threshold becomes the overall overspeed 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

FieldbusClosedA Fieldbus is an industrial network system for real-time distributed control (e.g. CAN or Profibus). It is a way of connecting instruments in a plant design Parameter Index Sub-Index Data Type Float Scale Units Access PDOClosedPDO is a type of protocol frame used in some fieldbuses. A PDO contains one or more object dictionary entries, which define the application data transferred between devices. Mappable
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 AXIS1.VL.THRESH 0x5011 0x8 UDINT - Velocity RW False
