Series
High starting torque, efficient operation and simple debugging. It can easily debug complex motor settings and achieve high starting torque above .3.

Used in elevators, the torque can be ensured even if the speed is commanded. It is most suitable for elevators such as cranes that require instantaneous torque from low speed when starting.

The overcurrent suppression function (high-speed current control) and overvoltage suppression function greatly speed up the internal calculation speed of the inverter and greatly improve the current control performance. The overcurrent suppression function and overvoltage suppression function can be used according to the load requirements. Adjust the necessary acceleration and deceleration time to reduce the occurrence of tripping

One button can realize the emergency stop of the inverter output without passing the frequency conversion, and shutting down the output through the hardware loop can realize a safe and reliable emergency shutdown action

Micro surge voltage suppression function (applied for patents in Japan, the United States, South Korea and other countries)

Expanded models with built-in regenerative braking circuit (B) (below)

Equipped with a noise filter

The installation of the built-in zero-phase reactor complies with the specifications of the Ministry of Transportation and Communications across the country

Using long-life parts, fans, capacitors and other devices, the product has a service life of 10 years Above, the lifespan diagnostic function will send out lifespan warning signals. Receive signals for repair before a fault occurs

Analog input disconnection detection function

Smart input terminal response time setting

Smart input terminal pulse Read

Programmable function steps save cost
