AC INVERTER DRIVES
Litzler Vector AC inverter drives provide the highest level of
accuracy available and are controlled by LMMI to maintain speed,
tension and stretch.
- Stretch
is maintained within ±0.1 percent of the setpoint.
- Tension
is maintained within ±0.1 percent of the total
rated value.
- Speed
is maintained to an accuracy of ±0.01 percent
of set speed.
- Precision
control allos a speed change from maximum to zero without loss
of tension or damage to the tire cord.
AC inverters have a power factor up to .98 and are powered through
a common DC buss. Each drive redistributes power depending on
whether it is
motoring or regenerating. This power distribution reduces utility
costs by using only 25 to 30 percent of the total rated (kw)
of all drives.
