MC-Basic:axis.VELOCITYOVERSPEED

Sets or queries the axis VELOCITYOVERSPEED value. VELOCITYOVERSPEED defines an absolute motor velocity limit. When this limit is exceeded, an error is generated and the axis is brought to an immediate stop. While stopping, the overspeed condition is not checked. Further action may be taken by the program error handler.

	NOTE
	VelocitySafetyLimit and VOSPD should be greater than: 1000/ser.cycletime/VFac. In cases where vfac is set too low regular velocity values can trigger these.

Short form

<axis>.VOSPD

Syntax

<axis>.VelocityOverspeed = <value>

?<axis>.VelocityOverspeed

Availability

All versions

Type

Double floating point

Range

Greater than zero.

Units

User axis velocity units, as given by <axis>.VELOCITYFACTOR

Default

1.2×Vmax

Scope

Configuration, Task or Terminal

Limitations

To set the value within a task, the axis must be attached to that task (using the ATTACH command).

Examples

A1.VelocityOverspeed = a1.vmax
