  • Specification Data
Product introduction
AS700 series inverter for four-quadrant port machinery is specially designed for the industrial hoisting field, such as large portal hoist, gantry crane, shore bridge, bulk cargo, crane, and has successfully applied in the industries such as paper making, metallurgy, mining, cement, energy, chemical, petroleum and natural gas, etc.
AS700 series inverter for four-quadrant port machinery is a highly flexible AC drive product with below outstanding features: customized to meet the user's individualized needs; wide range of power and voltage, including maximum 690V industrial voltage; several built-in options; programmable to meet different application needs.
Functional features
Complete energy regeneration drive
AS700 series is a compact cabinet drive configured with energy regenerative power supply unit. This drive includes all parts that are running with energy regenerative including filter at incoming line side. Energy regenerative power supply unit allows energy conversion between motor and generator mode. One of the main design concepts of STEP industrial drive is to ensure the product with long service life. Consumable parts such as fan, capacitor would be selected with the type based on the principle of extension of service life. Meanwhile the product has strong protection which is well-known under this continuously growing industry fields.
Energy saving
AS700 is more energy saving compared with other braking methods (such as mechanical braking, resistance braking). Energy regenerative drive has obvious energy saving advantages, i.e. energy direct feedback toward grid without heating consumption. As external braking resistance is not required, it could be easily installed with smaller space.
High performance
AS700 enables very quick conversion between electric and power generation mode, which is based on quick control performance of vector technology. Energy regenerative power supply unit can improve output voltage, and even if input voltage is lower than rated value, it can still output rated voltage with full amplitude. This unit based on vector control can also compensate instant fluctuation of grid voltage. Therefore, even if the power voltage drops, the device will not be damaged or fuse blown.
Wide application
AS700 standard configuration can meet different application needs. The cabinet drive series own wide features and built-in options.
