Function Block Diagram
Description
Input handling to the DMC 2 .
Digital output handling from
the DMC 2 unit.
Calculates the momentary
desired values of speed and
position.
Controls the motor speed and
position according to the
momentary set points and the
measured speed and
position. Compensates for any
speed or position error.
Adapts the motor drive to the
electrical characteristics of the
motor.
Allows the PL2 code to detect
and respond to alarm and
safety signals generated in
hardware protection systems.
Allows certain hardware
functions (i.e. enabling the
power stage or activating
brake relay or LEDs) to be
controlled by the PL2 code.
Allows the PL2 code to
monitor analog signals either
by direct reading or by
”connecting” it to an internal
variable.
Allows the PL2 code to set
analog outputs to specific
values or ”connect” it to an
internal variable.
Allows the FW system and the
PL2 code to access
position and velocity, not only
of the controlled motor but
also of one auxiliary resolver.
Allows the motor set position
to be controlled by the
auxiliary resolver speed and
position, in such a way that an
electronic gearing is achieved.
Pdata acc is a data array that
allows the PL2 programmer to
