While ‘Up’ push button is pressed, the speed increase can be set according
to a double ramp in group G5 ACCELERATION AND DECELERATION
RAMPS. In case of decreasing the speed occurs the same thing, this is, that
decrease can be set in the same way:
‘G5.7 Î Ramp 1 for reference increase of motorized potentiometer’
‘G5.8 Î Ramp 1 for reference decrease of motorized potentiometer’
‘G5.9 Î Ramp 2 for reference increase of motorized potentiometer’
‘G5.10 Î Ramp 2 for reference decrease of motorized potentiometer’
‘G5.11 Î Speed for changing the acceleration and deceleration ramp’
See group G5 ACCELERATION AND DECELERATION RAMPS for
additional information about these parameters.
Note: In this mode, the speed reference set by the potentiometer will be
memorized even if the motor is stopped, and also if the power supply is lost.
Note: For using this function it is necessary to set ‘G3.1 Î Reference
source 1 of speed’ or ‘G3.2 Î Reference source 2 of speed’ with option
‘PMOT’ according to the selected source.
We can observe the operation of the motorized potentiometer in the
following figure.
