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

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.

Marine application is not considered to be 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
