Today's
innovative building services impose a wide variety of demands on
drive systems. As a result more planners are now looking for open,
flexible and fully-scaleable drives. Additional requirements include
user-friendliness, network support and, of course, maximum
reliability - particularly in heating, ventilation and
air-conditioning (HVAC) applications. The drives must also be
economical to use, combining minimum operating costs and maximum
energy savings.
Plus extensive
advanced technology functions like:
- SLV-
Vector Control and V/f Control (fully programmable)
- Online
Autotuning and automatic slip compensation for outstanding speed
stability
- Soft PWM
function for reduced motor noise
- Active
current limiting (tripless operation)
- Automatic
restart after power failures
