7.9.3 Ramp
The ramp function limits the slew rate of the input signal.
Figure 116: Ramp function
This function limits the output signal's rate of change to <VelocityDemandRamp> (0x5553) per 1/10000 sec-
ond. The ramp function is disabled (output = input) if this parameter is zero.

7.9.3.1 Object 0x5553: Velocity demand ramp
This parameter defines the demand signal's maximum rate of change.
Max rate of change per second = <VelocityDemandRamp> (0x5553) x 10000
