Mechatronic

Watt Mechatronis - Geared motor systems:
Mechatronics (a thought-up word taken from mechanics and electronics) stands for the technical connection between the disciplines of electro-technics, electronics, informatics, engineering, drive technology and construction and can be applied wherever an intelligent link can be made between these areas resulting in an increase in the overall functionality of a product, or if costs can be optimised.
Watt Drive implements these links to the individual disciplines in the new software "cat4CAD 4.0", where perfectly coordinated components from the Watt portfolio are combined together to form a reliable system.

Drive Electronics

The frequency inverter programs S-line, B-line, E-line and P-line consistently follow the same principle in the range of 0.2 to 90 kW as the Watt Drive modular drive systems. These frequency inverters distinguish themselves through their excellent control features, compact size, ease of use and very good communication skills.
The differences between the four programs lie primarily in the control features and thus the starting torque and dynamic performance achieved. The S models are V/F controlled, while the B, E and P range consists of vector-controlled frequency inverters. The E-line offers implemented EMC filters and brake choppers in series, as well as many possible extensions for the digital and analog in- and outputs. Moreover an integrated SPS control is available. The P range features distributed intelligence e.g. for positioning tasks. This complete range of modular drive control units offers the technically best and most cost-effective drive solution for any requirement, from simple open loop control to top dynamic closed loop process control and positioning applications. Watt Drive is able to offer a complete range of modular drive control units and the most cost-effective drive solution for any requirement, from simple control and drive tasks to the control of top dynamic processes and positioning.

Control and display devices

To aid control of inverter systems, a number of top quality, high performance and universally operated products are available in the form of a range of operator panels. They all enjoy extreme ease of use and high functionality, while the concept on which they are based is attractive and easily adaptable.

There are 4 different operator panels, which differ in use, memory size and display. All four are run using the same program software for pre-settings and a pre-configured interface to the frequency inverters in the Profi-line series. Communication can run via the RS232 or via CANopen - both interfaces are standard on board components of the P6000 frequency inverter.

Software

The program software “VFDSoft” and PROFI Tool” allow programming of the inverter using a PC.

The “VFDSoft” is for programming the frequency inverter series S-, B and E-line. With the "WPLSoft" it´s possible to programming the internal SPS function. Only for E-line. The frequency inverter series P-line P6000 is parameterized and programmed with “PROFI TOOL”.
