Inverters: payback in 12 months in HVAC?
No matter what area of plant control you choose to scrutinise, there are few optional equipment alternatives that offer the operational benefits and cost savings of frequency inverters.
As well as providing a smooth soft start which reduces mechanical shocks and peak currents, it also simplifies cabling, reduces cabinet space and can be operated without any specialist expertise.
Its rated power of 0.25 to 4kW with a max output of 9.5A suits three-phase motors and it can be used with single motors, reversing operations or multi-motor control.
In the past motor starters have been electromechanical devices in the control cabinet, for switching and protecting three phase AC motors up to 4kW.
The systems were normally wired with each motor connected individually to the panel, requiring a great deal of time and cost to install.
With the introduction of Lenze's Starttec control has now moved to the heart of the material handling process.
Benefits of the Starttec electronic motor over conventional switchgear are that Starttec cuts wiring costs and installation time as it eliminates the need to individually wire from each motor back to the cabinet as power can be taken by spur from an energy bus or looped through from Starttec to Starttec.
Its design has many other benefits as starting is wear-free, and installation onto the motor or a nearby machine frame is possible due to a high protection class of IP65.
The Starttec can be programmed using logical functions such as AND, OR, XOR and NOT, meaning that a conveyor belt driven by one of Lenze's geared motors with Starttec only starts if the necessary conditions, eg sensor 1 and 2 are active, are fulfilled.
Each distributed Starttec performs its own intelligent operation, thereby relieving the load on the central PLC.
For a total system Lenze offer the Starttec for fixed speed distributed drives and the 8200 Motec frequency inverter for variable speed drives together with an extensive geared motor range.
Such a reliable and flexible drive system allows the material handling application to run efficiently.
Starttec can be controlled by a simple digital signal, however further options allow control via fieldbuses that include AS-i, Interbus, Profibus-DP and CAN. Request a free brochure from Lenze ...
