Modbus Motion Interface

Read_Single(<AxisOrGroupPage>_+_ProfileVelocity_s);

Description

Profile Velocity returns the current commanded speed (signed magnitude) that is being used to generate the trapezoidal motion trajectory. During slew, the magnitude of Profile Velocity is the same as Speed. During Accel and Decel the profile velocity varies linearly with progress through the phase. The value returned is the value of the trapezoidal profile, not the actual motor speed itself. Reading the actual speed requires an application program that differentiates position information and returns a value in a user variable.

Escapes

The Profile Velocity register does not generate any escapes.

Examples

This reports the current commanded speed of axis 2:

CurrentSpeed:=Read_Single(Axis2_+_ProfileVelocity_s)
