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.
