Ramp-function generator configuration / RFG config

VECTOR_G Can be changed: U, T
Data type: Unsigned16
P-Group: Setpoints
Not for motor type: -
Min
-
Description: Sets the configuration for the extended ramp-function generator.
Bit field: Bit
00
01
02
Dependency: Re bit 01, 02 = 1:
These bits are only effective when ramp-function generator tracking is activated (p1145 > 0).
When both bits are activated, RFG tracking with polarity change is active.
Re bit 01 = 0, bit 02 = 0:
When ramp-function generator tracking is active, the setpoint can only change in the direction of the target setpoint –
or be frozen.
Notice: Re bit 00 = 1:
If the ramp-up time is longer than the ramp-down time (p1120 > p1121), then there is an acceleration step at the zero
crossover. This can have a negative impact on the mechanical system.
Note: Re bit 00 = 1:
When the direction change is changed there is no rounding-off before and after the zero crossover.
Re bit 01 = 1:
For load surges, the ramp-function generator output tracks the actual value. The tracking (correction) ends at a
setpoint of zero.
Re bit 02 = 1:
For load surges, the ramp-function generator output tracks the actual value. For a polarity change, the tracking
(correction) is continued.
