Changing over time ramps
During operation, you can change over from the time ramps set
under PNU F002 and F003 to those programmed under PNU A092
and A093. This can be done either by applying an external signal
to digital input 2CH at any time or when the frequencies
configured under PNU A095 and A096 are reached.
Use PNU A094 to set the changeover mode.
X Use PNU A095 to define the required output frequency for
automatic changeover.
X Configure one of the digital inputs as 2CH by entering the value
09 in the corresponding PNU C001 to CC005.
The deceleration time is set with PNU A093 and A096.
