desired acc and the number of

be maintained.

Pdata pos allows the PL2
programmer to create
electronic cams. For each
position of the aux. resolver,
the desired position of the
motor is maintained.
The following table explains block functions merely providing support to the PL2
programmer. These function blocks are less related to hardware functions:

TMR The timer system provides
timing and delay facilities to the
PL2 programmer.
Int The interrupt system allows the
PL2 programmer to enable or
mask certain interrupt sources
and control interrupt trigger
criteria, i.e. positive or negative
edge of an input signal.
Vector The interrupt vectors direct
program execution to the
desired interrupt service
routine, upon interrupt
detection.
Capture The input capture function is
allowing the PL2 code to
measure the exact time, when
an edge was detected on the
high speed input.
EEProm For non-volatile storage of PL2
software parameters, EEProm
hardware is provided.
Comm Allows the PL2 programmer to
customize the serial
communication parameters.
