• Built-in braking unit configured for the entire series

* Dedicated terminal design, diverse choices

* Special-purpose braking logic:
- Special-purpose braking logic: Integrates with torque verification to achieve safe run without slip after torque establishment;
- supports starting direction selection and brake selection in FWD/REV switchover to meet various starting requirements flexibly.

* Application macros:
Integrates a variety of crane application macros and supports user-defined macros, which are easy to commission and use.

* Conical rotor motor control:
Helps adjust the magnetic flux based on the characteristics of conical rotor motor to realize fast brake release and closing control, simplify the commissioning steps, and ensure equipment safety.
