| Watt Mechatronics -
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 WATT
MECHATRONIC catalogue, where perfectly coordinated components from the Watt
portfolio are combined together to form a reliable system.

| Drive Electronics |
The frequency
inverter programs ECO-line, OPTI-line and PROFI-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.

| Inverter E-line VFD-E
|
The NEW modular frequency inverter VFD-E.
From the experiences made with ECO- and OPTI-line there has been developed a new
motor drive.
The targets were, integrated line filter and brake chop-pers, as well as an easy
selection and handling, stur-diness and a modular drive philosophy, as to find
an optimal solution in both economical and technical as-pects on every demand
for a motor drive.
Technical Data:
Voltage: 1 ~ 230V und 3 ~ 400V/460V
Control: U/f + SVC + VC
Area of performance single-phase: 0.25kW - 2.2kW [1/3HP to 3HP]
Area of performance three-phase: 0.4kW - 22kW [1/2HP up to 30HP] |
|
| Inverter S-line VFD-S
|
Integrated flexibility at a low price.
The frequency inverter VFD-S from the S-line program is particularly suitable
for applications whereby cost-effectiveness plays a central role. However, it
also offers many other opportunities, which are outstanding in this category,
for example, motor slip compensation, parametric U/f characteristics, etc.
The VFD-S unites innovative technology, a high level of performance and
functionality with a compact design and a wide scope of application. The
simplest start up of operations, of use and parameterization distinguish this
frequency inverter.
Technical Data:
Voltage: 1 ~ 230V und 3 ~ 400V/460V
Control: U/f (with slip compensation)
Area of performance single-phase: 0.25kW - 2.2kW [1/3HP to 3HP]
Area of performance three-phase: 0.75kW - 2.2kW [1HP to 3HP] |
|
| Inverter B-line VFD-B
|
The multi-talent for high torque.
The VFD-B power packet from the B-line range with the new sensorless vector
control (SVC) provides a superior torque for demanding applications consistently
over the whole performance range. This SVC is supported by a static/dynamic
motor autotuning in order to adapt control to any circumstances occuring during
operations of the specific application in an optimal manner. The frequent spread
of standard factory models of machine parameters is thus wholly compensated.
This internal control procedure means that especially in the lower torque range
a previously unattainable torque curve is possible.With the optional feedback
card, the VFD-B is perfect for complex closed loop control tasks.
Technical Data:
Voltage: 1 ~ 230V und 3 ~ 400V/460V
Control: U/f + SVC + VC
Area of performance single-phase: 0.75kW - 2.2kW [1HP to 3HP]

|
The unique, intelligent all-rounder.
The frequency inverter P6000 enhances the functionality of the frequency
inverter range. With its modular design, flexible programmability and integrated
positioning control, the user has the possibility to transfer control
intelligence to the inverter and therefore relieve SPS for more integral tasks.
Technical Data:
Voltage: 1 ~ 230V und 3 ~ 400V/460V
Control: U/F, Torque- and Position control
Area of performance single-phase: 0.75kW - 1.5kW [1HP to 2HP]

| Soft starter RVS
|
Our soft starer from the production series RVS-AX (analogue) as well as the RVS-DN
(digital) provide for soft, smooth machine acceleration. With this type of
start-up, the AC motors being driven and the coupled mechanical machine
components are not exposed to any shock impact loads, therefore wear and tear of
mechanical elements is avoided.
The starting current is considerably reduced, in comparison to a DOL-starting.
Thus all components (AC motor, mechanical machine elements) are preserved and
are able to be dimensioned more cost effectively.
Technical Data of RVS-AX:
Voltage: 230, 400, 440, 460 und 600V
Control: Sanftanlauf und -Stopp
Current range: 8 - 170A
Technical Data of RVS-DN:
Voltage: 220 - 1000V
Control: Sanftanlauf und -Stopp, Boost-Start
Current range: 8 - 2700A |
|
| 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.
