| 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 to avoid frequent overvoltage/over current tripping | |
| Rapid current limit | It decreases the over current faults to the minimum and ensures normal running of the AC drive | |
| Torque limit and control | It automatically limits torque during running, preventing frequent over current tripping | |
| Excellent performance | It implements control on the asynchronous motor and synchronous motor with the high-performance current vector control technology | |
| Power dip ride-through | It reduces set frequency for load to maintain normal output of the AC drive when the bus voltage remains low, preventing the undervoltage fault during running | |
| Low voltage protection | In the case of sudden bus voltage reduction or power failure, the AC drive stops quickly and restricts the running to prevent hook gliding | |
| Overload protection | It automatically identifies the load condition, and restricts the hoist running after | |
| overload, but allows only the descending running | ||
