Merits of inverter drives
Extruders with inverters have the following merits:
- Stable speed operations at any speed
It is important for extruders to keep pushing out speed because
pressing percentages and shapes depend on those speeds.
- Stable speed operations by the 'PG feedback vector control'
The 'PG feedback vector control' has a good performance and a high accuracy.
- Constant torque operations
The torque control in 'PG feedback vector control' can keep output torque constantly.
