For the pass years, the company has established a global equal and close cooperation agent system, and customer service system with user satisfaction as an indicator, widely used in ceramics, packaging, textile, dyeing and finishing, engineering upgrading, lifting, road, CNC machine tools, glass, mining, petroleum, shipbuilding, military and even farming and animal husbandry and other equipment fields.

S3100A/E series of products is an upgraded version of our S3100 series inverter. Under the premise of ensuring the original high configuration of the hardware remains unchanged, the operation mode is adjusted according to the usage habits of domestic customers, and the driver performance and functions of the bottom and application layers of the software are respectively improved:

• Support asynchronous motor and permanent magnet synchronous motor control.
• The maximum starting torque is 0.5Hz, 200%, and the speed accuracy is 0.1%.
• The latest vector algorithm of permanent magnet synchronization, start without reversal. Support 3200Hz high frequency output.
• Simple PLC, built-in swing frequency function.
• Can realize the main and auxiliary frequency superposition control.

For More Convenient Maintenance

• Integrate into the easy disassembly modularization factor.
• The maintenance is easier and it is convenient to sink heat and clean internal.

Common DC Bus

All the power range support the common DC bus application, to share with the energe, and reduce the braking resistor power or cancel the brake resistor.

More Comprehensive Protection

• More optimized module temperature management. If the temperature of environment is high or over loading, it can protect more ti-mely and considerately.
• More optimized short-circuit protection.
• 2T series 4.0kW, 4T series 5.5kW and below, equipped with built-in charging resistor overheating protection unit.

More Flexible Operation
External input terminal can select the two working modes, NPN, PNP to connect with external PLC and touch screen neatly.

Characteristics

• The overload capacity is 150%-60 seconds for the G type and 120%-60 seconds for the P type.
• The maximum starting torque (SVC) is 200%-0.5Hz, and the speed accuracy is 0.1%.
• The latest vector algorithm for permanent magnet synchronization does not reverse when starting.
• 3-point V/f curve setting, 6 sets of V/f curve setting, V/f separation control.
• Instant stop function, speed tracking function, effective brake suppression function.
• Instantaneous stop non-stop function, speed tracking function, effective brake suppression function.
• Built-in PID function, simple PLC function, swing frequency function.
• Multi-channel multi-function terminal, include optional function 1 high-speed pulse input, 1 high-speed pulse output.
• The external terminals can be selected from NPN and PNP modes, which are more flexible with external PLC and touch screen. Built-in brake transistor for power models up to 22kW.
• Switch to high frequency (3200Hz) output.
• With double limit specification: G type heavy load / P type light load specification can be set by parameters.
• Provide a variety of fault protection functions: inverter short circuit protection, over voltage, over current, overload, over temperature and other protection functions.

Various Application

• S3100A/E series is an enhanced current vector control general-purpose inverter, supporting asynchronous motor and pe-rmanent magnet synchronous motor control, DSP control system main chip upgrade, a new high-performance current v-ector control method (SVC), V/f control, V /f separation control, torque control.
• The application is more flexible and the performance is more stable. It can be widely used in applications with high requi-rements for speed control accuracy, torque response speed and low frequency output characteristics.

Function Description

Multi terminal ports:

Fast current limiting: The fast current limiting function can avoid the over current alarms in the inverter freque-ntly. When the current exceeds the current protection p-oint, the fast current limit function can limit the current within the current protection point quickly to protect the safety of the device and avoid over current alarms cau-sed by sudden load or interference.

Chemical fiber and other industries needing for traverse, winding frequency swing function: make the forming sp-indle flat, no drum.

Powerful current vector control and high starting torque: No speed sensor vector control support to run under condition of block running. Under 0.5Hz, the rated out-put torque is 200%; Sensor-less vector control reduces sensitivity to motor parameters and improves field ada-ptability.

Instantaneous power failure without stopping: It means that the inverter will not stop when there is an insta-ntaneous power failure. In the case of instantaneous po-wer failure or sudden voltage drop, the inverter reduces the output speed, and the load is fed back to the energy to compensate for the voltage drop to keep the inverter running for a short time.
