Performance and Functional Details
- Four-Quadrant Operation: Supports forward/reverse rotation and motor/generator modes, enabling regenerative braking to feed energy back into the grid.
- Field Control: The integrated controllable field rectifier supplies 325 V DC / 10 A to the motor field winding, allowing independent adjustment of the field current for optimized motor performance.
- Regulation Accuracy: High-precision speed and current regulation with low output voltage/current ripple for smooth motor operation and dynamic load changes.
- Dynamic Response: Fast current and speed response times, suitable for applications requiring rapid acceleration/deceleration and precise torque control.
- Configuration and Programming: Parameters can be configured via the operator panel, SIMOREG PC Tools, or compatible software, supporting custom control logic and application-specific settings.
