Type Access Description
U8 RO The values shall be given in rotations
per minute (rpm) or in user-defined
velocity unit if the Vl Dimension Factor
object is not set to 1.
U32 RWW Always zero.
U32 RWW Mapped internally to the Vl Velocity Max
Pos and Vl Velocity Max Neg values.
U8 RO This object indicates the configured
delta speed and delta time of the slope
of the acceleration ramp:
/ Delta Time
U32 RWW The value shall be given in rotations per
minute (rpm) or in user-defined velocity
unit if the Vl Dimension Factor object is
not set to 1.
U6 RWW Value shall be given in seconds.
U8 RO This object indicates the configured
delta speed and delta time of the slope
of the deceleration ramp:
Vl Velocity Deceleration = Delta Speed
/ Delta Time
U32 RWW The value shall be given in rotations per
minute (rpm) or in user-defined velocity
unit if the Vl Dimension Factor object is
not set to 1.
U6 RWW Value shall be given in seconds.
U8 Const This object indicates the configured
numerator and denominator of the Vl
Dimension Factor. The Vl Dimension
Factor serves to include gearing in
calculation or serves to scale the
frequencies or specific units of the
user. It influences the Vl Target
Velocity, Vl Velocity Demand, Vl Velocity
Actual Value as well as the velocity limit
function and the ramp function.
INT32 RW Multiplier for VI velocity values. Shall
not be 0.
INT32 RW Divider for VI velocity values. Shall not
be 0.
Vl Velocity Acceleration = Delta Speed
