The core of efficient operation of logistics machinery: INVT GD600A frequency converter
1、 Fast and dynamic response, improving the efficiency of logistics equipment start stop
Logistics machinery such as stackers, conveyors, sorting machines, etc. require frequent start stop and acceleration/deceleration, and have extremely high requirements for the dynamic response capability of frequency converters. In the PG vector control mode of GD600A, the torque response time is less than 5ms, which can quickly respond to control instructions, greatly improving the operating speed and sorting efficiency of logistics equipment, and meeting the high cycle operation requirements of modern logistics centers.
2、 Zero speed hover function ensures safe cargo handling
During the process of cargo handling and stacking, the equipment needs to maintain stable torque output at zero speed to prevent cargo from slipping. INVT GD600A supports a zero speed hover function with 150% rated torque, which can keep the motor stationary for a short period of time. Even under heavy loads, there will be no rolling phenomenon, fully ensuring the safety of logistics operations.
3、 Common busbar energy feedback reduces wasted braking energy
Frequent braking of logistics equipment generates a large amount of regenerative energy, which is mostly wasted in the form of thermal energy through braking resistors in traditional solutions. The common DC bus architecture of GD600A can feed back the energy generated by braking to the DC bus for use by other units in electric state, which not only reduces energy consumption but also reduces the heating and loss of braking resistors.
4、 High anti-interference design, suitable for complex industrial environments
Logistics centers often have a large number of electrical equipment and complex electromagnetic environments. The PG card of GD600A adopts digital filtering technology, which increases the anti-interference ability by more than 1 times, and the encoder signal can still maintain stable reception during long-distance transmission. At the same time, the product has passed strict EMC testing and can meet the electromagnetic compatibility requirements of IEC61800-3 C3 level, ensuring stable operation in complex environments.
