Features
Profibus communication expansion card can be built-in.
Easily removable keypad for remote operation.
In low-temperature environments, the motor is heated before operation without the need for external heating equipment.
Overvoltage protection, undervoltage protection, overcurrent protection, overload protection, stall protection, bypass fault, thyristor fault, three-phase current imbalance, motor overheating protection, etc.
Unique start and stop control for pump loads. The pump starting function reduces the starting current of pump loads; the pump stopping function reduces the water hammer effect.
Self-service cleaning of siltation in the pump to prevent overflow, overload and other failures caused by blocked rotor.
Dynamic braking can quickly stop the running load; static braking can bring the running load to a stop state under the action of external force.
It has the functions of low-speed forward rotation and low-speed reverse rotation, and can adjust the load running direction at low speed before the motor starts normally.
220V-500V main power input voltage.

Applications
Application of dynamic braking function:
Dynamic braking can be used to quickly stop large inertia loads and solve the problem of long shutdown time of large inertia fans.
Application of static braking function:
When the fan rotates due to external wind force, the static braking function can stop the fan first so that it can be started later.
Comprehensive moisture-proof and anti-corrosion solution
Unique pump control features:
Why is the pump control feature needed?
Pump systems are susceptible to fluid shock and surge during motor starting and stopping.
The pump control function can effectively control the load current when the pump starts and stops, extending the pump life.
When starting:
In pump starting mode, the output voltage increases according to the pump load characteristic curve until the output voltage reaches full voltage.
When stopping:
The pump stop curve can effectively slow down the water hammer phenomenon caused by the pump load when it stops.
Application scenarios for pump cleaning:
When the blades are blocked by mud, the starting current of the water pump will be too large, resulting in overcurrent or overload protection. After using the pump cleaning function, the impeller is self-cleaned before the water pump is started to ensure normal pumping.
