Bits 4...6 and 8 are not supported in the controlword in software version 2.1.
They can be used from version 2.2. Since this causes significant function changes
in the vl mode, this bits must be activated for compatibility reasons with bit 8 "ena-
ble vl ramp options“ in co32 state machine properties.
4.8.2.4 Ramp generator
The ramp generator supports linear ramps and those with linearly increasing accel-
eration (s-curves). Furthermore the behaviour can be parameterized flexible when
changing the direction of rotation.
