7.4.4.2 Object 0x63A3: Offset
This parameter is the offset of the linear output function.
Chapter "2.4.3 Units and prefix parameter", page 12
7.4.5 Ramp
The ramp function limits the slew rate of the input signal. The <Type> (0x63B0) parameter is used to activate
a one-quadrant, two-quadrant or four-quadrant ramp or to deactivate the ramp function.
If the ramp function is running or the ramp function is stopped by the bit 15 (ramp stop) of the #ControlWord#
signal the following <StatusWord> (0x6041) bits are set:
