| Onboard multiple preset speeds | It implements up to 16 speeds via the simple PLC function or combination of X terminal states | ||
| Onboard PID | It realized process-controlled closed loop control system easily. | ||
| Auto voltage regulation (AVR) | It can keep constant output voltage automatically when the mains voltage changes. | ||
| Overvoltage / Overcurrent stall control | The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to overvoltage / overcurrent. | ||
| Torque limit and control | It can limit the torque automatically and prevent frequent over current tripping during the running process. Torque control can be implemented in the CLVC mode. | ||
| Individualized Functions | Support for multiple PG card | Supporting for rotating transformer PG card, differential input PG card, UVW differential input PG card, resolver PG card and OC input PG card | |
| Power dip ride through | The load feedback energy compensates the voltage reduction so that the AC drive can continute to run for a short time. | ||
| Rapid current limit | It helps to avoid frequent over current faults of the AC drive. | ||
| High performance | Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology. | ||
