This function is enabled by solder bridges J2 , J4 (closed).
It allows adjustment of the ramp slope during both
acceleration and deceleration.
Adjusting the ACC potentiomenter, located in front of the
drive, clockwise (cw)increases the ramp time between 0,1
and 1S (It corresponds to 10V reference). (See note 1)
It is also possible to modify the range of the ramp opening
solder bridge J3 and mounting a resistor in the socket between
pin 8 and 17 (RAMP res. ).
The proper value is reported on the table below.
