vl Dimension Factor (numerator)

This object indicates the numerator of the ‘vl dimension factor’.

The  vl Dimension Factor (numerator) is used 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 Control Effort as well as the velocity limit function and ramp function.

The purpose of the ‘vl dimension factor’ is to convert the ‘user-defined velocity unit’ to the revolution/minute unit (rpm):

Velocity [user-defined unit] x  vl Dimension Factor (numerator)  = Velocity [rpm]

The  vl Dimension Factor (numerator) shall be in the range of -2147483648 to +2147483647, but the value 0 shall be not used.
