1. SPX Advanced application – introduction
Software SVCH0203, SPX Advanced application
SPX Advanced application has advanced power handling
features, main focus being in different kind of propulsion
systems. This application can be used also for winch control
where smooth brake logic makes it possible to use a
multi-motor winch system by just entering few additional
parameter settings that are explained in this manual without
forgetting permanent magnet motors.
1.1 Basic features
The SPX Advanced application provides a wide range of
parameters for controlling induction motors and permanent
magnet motors. It can be used for various kinds of different
processes where wide flexibility of I/O signals is needed
and only simple PI control logic.
The main focus has been how power reference, power
limits and torque limits behave in different situations.
The application allows power and torque reference and
reference ramp up rate adjustment to make the operation
smooth for ship generators and mechanics.
Flexible ID control possibilities takes the application
suitability to different process to a new level, allowing any
input or actual value to be connected to any parameter with
a scaling factor.
Additional functions:
•
Joystick input dead zone
