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
1. More optimized module temperature management. If the temperature of environment is high or over loading, it can protect more timely and considerately.
2. More optimized short-circuit protection
3. 220V with power range below 3.7kW and 440V with power range below 5.5kW is built in with charging resistor overheat protection unit(for other power range, it is optional )
More flexible operation
External input terminal can select the two working modes, NPN, PNP to connect with external PLC and touch screen neatly.
High start torque, available to achieve 150% of torque output on low speed 0.5Hz.Control method: V/F control, Dynamic torque vector control.
Support many frequency setting methods: digital setting, analog quantity setting, pulse setting, PID setting, communication setting etc.
16 sections, multi-velocity control and PID control.
Support DC braking of stop and external terminal control DC braking.
With overtorque detection.
With auto voltage adjustment. The output voltage would be stabilized automatically when the grid voltage varies.
With jump frequency control, make the system stabler and more reliable on mechanic resonance.
The input and output terminal are auto-program, user could make many working modes according to the needs.
Attached with many fault protection functions: converter unit protection, overvoltage protection, overcurrent protection, overload protection, overheat pretection etc.
S3100 series is new generation,Multi-function, Vector control inverters. It could widely applied on the fields that have high requirements on the speed control accuracy, torque response speed, low frequency output performance.
