Electronic motor starters and drives
Frequency inverters DF5, DV5, DF6, DV6 |
| |
| Characteristics of frequency inverters DF5, DF6 |
- Infinitely variable speed control through voltage/frequency
control (U/f)
- High starting and acceleration torque
- Constant torque in motor’s rated range
- EMC measures (optional: radio interference filter, screened
motor cable)
|
| Additional features of sensorless vector control for frequency inverters DV5 and DV6 |
- Infinitely variable torque control, also at zero speed
- Low torque control time
- Increased concentricity and constancy of speed
- Speed control (options for DV6: control module, pulse generator)
|
The DF5, DF6, DV5 and DV6 frequency inverters are factory-preset for their assigned motor rating, allowing drives to be
started immediately after installation.
Individual settings can be made with an optional keypad. Various control
modes can be selected and configured in a number of layers,
For applications with pressure and flow control, all devices contain a
built-in PID controller that can be matched to any system.
A further advantage of the frequency inverters is that they eliminate
the need for external components for monitoring and motor protection. On the mains side, only a fuse or circuit-breaker (PHKZ) is needed for line
and short-circuit protection. The frequency inverter’s inputs and outputs are monitored internally by measurement and control circuits,
such as overtemperature, earth fault, short-circuit, motor overload, motor blockage and drive belt monitoring. Temperature measurement in the
motor winding can also be incorporated in the frequency inverter’s control circuit through a thermistor input.
