1.2 Basic Features
The Marine 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 which
require wide flexibility of I/O signals and only simple PI control logic is needed.
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 take 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.
Marine application is not considered to be a fast response application. Basic functionality is
handled in 20 ms time level. Most of the inputs and output functions are handled in 30 ms
time level, and analogue output singles are using pre filtered signals (Torque (1 second
linear filtering) , Power, etc.). Power limit functions are handled in 10 ms time level or faster.
Additional functions:
•
Joystick input dead zone
•
Different power limits by DI or from Fieldbus. Motoring and generating side.
•
Master Follower function for steering propeller and double winding motors
•
Different torque limits for motoring and generating side
•
Cooling monitor input from heat exchange unit with selectable response.
•
Brake monitoring input and actual current monitor for immediate brake close.
•
Separate speed control tuning for different speeds and loads
•
Inching function with two different references
•
Possibility to connect FB Process data to any parameter and some monitoring
values
•
Analogue input 3 and 4 can control any parameter by ID number.
•
Support for four analogue output
•
Support for two PT100 board
•
Power limit ramp up rate adjustment
•
Torque limit ramp up rate adjustment
•
Automatic power reduction from DC Voltage
•
Actual power follower function, power will increase only with allowed rate
•
Condition Based Monitoring (license)
