POWER ELECTRONICS
RAMP 1 OF REFERENCE DECREASE FOR MOTORIZED POTENTIOMETER
Screen
Extended info.
Description
Range
Default value
Set on run
8 MPT DEC1=3.0%/s
Function
It allows setting the ramp 1 of reference decrease for motorized potentiometer
function. This function is configured in ‘G4.1.4 Î Selection of digital inputs
configuration’ with the option ‘4 Î MOTORIZED POT’ or ‘5 Î ERASAB POT’.
Additionally, it is necessary to set ‘G3.1 Î Reference source 1 of speed’ or ‘G3.2 Î
Reference source 2 of speed’ with the option ‘PMOT’ depending on the selected
source is 1 or 2. With this function, user can introduce the speed reference by means
of two push buttons connected to the digital inputs DI5 (up or increase the speed
reference) and DI6 (down or decrease the speed reference).
MOTO POT DEC1
Ramp 1 of reference decrease for motorized potentiometer function.
0.01 – 650%/s.
3.0%/s.
YES.
While we press ‘Down’ push button, we can decrease the speed by applying up to two
different ramps previously set (ramps 1 and 2 of reference decrease). The ramp
change is set in parameter ‘G5.11 Î Speed for ramp change with motorized
potentiometer’. If G5.11 is set to ‘OFF’, any ramp change will not be done. In this case,
the drive will search the reference speed by only applying the ramp 1 for reference
decrease of motorized potentiometer set in this parameter.
Setting is realized in deceleration units (decrease in % of speed per second).
See figure 10.24.

RAMP 2 OF REFERENCE INCREASE FOR MOTORIZED POTENTIOMETER
Screen
Extended info.
Description
Range
Default value
Set on run
9 MPT INC2=1.0%/s
Function
It allows setting the ramp 2 of reference increase for motorized potentiometer function.
This function is configured in ‘G4.1.4 Î Selection of digital inputs configuration’ with
the option ‘4 Î MOTORIZED POT’ or ‘5 Î ERASAB POT’. Additionally, it is
necessary to set ‘G3.1 Î Reference source 1 of speed’ or ‘G3.2 Î Reference source
2 of speed’ with the option ‘PMOT’ depending on the selected source is 1 or 2. With
this function, user can introduce the speed reference by means of two push buttons
connected to the digital inputs DI5 (up or increase the speed reference) and DI6 (down
or decrease the speed reference).
MOTO POT INC2
Ramp 2 of reference increase for motorized potentiometer function.
0.01 – 650%/s.
1.0%/s.
YES.
While we press ‘Up’ push button, we can increase the speed by applying up to two
different ramps previously set (ramps 1 and 2 of reference increase). The ramp
change is set in parameter ‘G5.11 Î Speed for ramp change with motorized
potentiometer’. The drive will apply the ramp 1 until the speed exceeds the value set in
G5.11. From that moment on, drive will start to apply the ramp 2. If G5.11 is set to
‘OFF’, any ramp change will not be done, and the drive will search the reference speed
by only applying the ramp 1 for reference increase of motorized potentiometer set in
this parameter.
Setting is realized in acceleration units (increase in % of speed per second).
See figure 10.24.
