| AC INVERTER DRIVES
Litzler Vector AC inverter drives provide the highest level of accuracy available
and are controlled by LHMI to maintain speed and tension.
- On
the critical drives (line master and metering rolls) speed
is maintained within ±0.1
percent of the setpoint
- Tension
is maintained within ±0.5 percent of the total rated
value
- Precision
control allows a speed change from maximum to zero without
loss of tension
- AC
inverters have a power factor up to .98
