E280 (2.2KW / 3HP)
Description
The compact yet reasonable structure reduces the volume of inverter 20%-30% times than the traditional general inverter; independent cooling duct and closed main loop design
Droop control function: automatically balance the power of the drive system of inverters on the same transmission chain.
Adopts DC fan characterized by the large volume, high wind pressure, excellent cooling effect, and stable performance
Particular self-adaptive control technology, allowing for automatic current and voltage limitation and under-voltage suppression during operation.
The standard configuration of RS485 communication interface, optional MODBUS protocol, and SUNFAR self-defined protocol; with linkage synchronous control function, allowing for easily communicating inverters with PLC, industrial personal computers, and other industrial personal types of equipment. Load auto-balancing function; when RS485 communication linkage control function is adopted, the master motor synchronously sends frequency and torque load commands to each slave motor, so as to achieve torque balancing of each variable frequency drive system.
E280 series inverter communication protocol is a kind of series master-slave communication protocol, in the network,
only one equipment, and master can build a protocol, (Named as “Inquire/Command”). Other equipment, slaves’
response “Inquire/Command” of master only by providing the data or doing the action according to the master’s
“Inquiry/Command”. Here, the master is Personnel Computer, Industrial Machine, or Programmable logical controller, and
the slave is the inverter. Master not only visits some slaves but also sends the broadcast information to all the slaves. For
the single master “Inquiry/Command”, all slaves will return a signal that is a response; for the broadcast information
provided by master, the slave needs not feedback response to the master machine.
