Object 204Ch: PV Scaling Factor
This object shall indicate the configured numerator and denominator of the pv scaling factor. The pv scaling factor serves to modify the resolution or directing range of the specified setpoint
Setpoint is the target value that an automatic control system, for example PID controller, will aim to reach. It is aso included in calculation of the vl velocity demand, and vl velocity actual value. It does not influence the velocity limit function and the ramp function. The value shall have no physical unit and shall be given in the range from -32 768 to +32 767, but the value of 0 shall not be used.
The velocity scaling factor is only active, when bit 4 of FBUS.PARAM05 is set to 1. Otherwise velocities are scaled as 1/1000 rpm.
