Application Areas
- Hoisting and Material Handling: Compatible with various hoisting equipment including overhead cranes and tower cranes. Features high-precision speed regulation via closed-loop control, SIL3-level safety functions, and wide power range for stability and safety during heavy-load operations.
- Mineral and Building Materials Processing: Drives heavy-duty equipment such as crushers and mills. Strong overload capacity, low-harmonic design, and multi-motor synchronous control reduce equipment wear and enhance processing efficiency.
- Rubber, Plastic and Chemical Production: Adapts to equipment like extruders and calenders. Supports multiple motor types with precise torque control and open/closed-loop switching for stable speed output in high-viscosity material processing.
- General Industrial Conveying: Powers various conveyors including belt and chain conveyors. Wide voltage compatibility, four-quadrant operation capability, and modular design suit long-distance, high-load material conveying scenarios.
- Complex Drive and Energy Recovery: Applicable to common DC bus and four-quadrant systems. Supports bidirectional energy flow, recovering electrical energy from motor braking. Abundant communication interfaces meet precise synchronization needs of complex multi-equipment systems.
Frequently Asked Questions
Q: When the ATV900 drives a crane, "speed drift" occurs during heavy-load lifting/lowering, and precise positioning cannot be achieved even in closed-loop control mode. What is the cause?
A: The core issue lies in encoder signal problems or mismatched torque parameters. Check encoder wiring for looseness and confirm encoder type matches inverter parameter settings. Adjust torque compensation parameters and speed dead band settings to avoid accumulated speed deviations.
Q: The inverter is used for an extruder and frequently reports "Over Torque Fault (OT)" during operation. However, the material viscosity is normal and the motor rated torque is not exceeded. How to troubleshoot?
A: Check torque limit parameters and motor type compatibility. Ensure load type is set to constant torque and adjust torque limit values. For PM motors, verify proper motor self-learning has been completed to prevent torque calculation deviations.
Q: After building a common DC bus system with the ATV900, "excessive bus voltage fluctuation" occurs during multi-inverter operation, and "Over Voltage Fault (OV)" is occasionally reported. What is the problem?
A: Check braking resistor selection and ensure total braking resistor power meets system requirements. Adjust bus voltage upper limit parameters and enable bus voltage balance control. Consider adding an Active Front End (AFE) to absorb excess energy.
Q: When the inverter controls a crusher, it reports "Overload Fault (OL)" instantly at startup. However, the motor starts normally under no-load and only triggers the fault under heavy load. How to resolve this?
A: Optimize startup parameters by changing from linear acceleration to ramp acceleration with torque boost. Extend acceleration time and adjust overload protection levels. Verify motor insulation and cable cross-section meet power requirements.
Q: The ATV900 communicates with a PLC via PROFINET to control conveyor synchronous operation. However, multiple motors run at unsynchronized speeds without communication fault alarms. What is the cause?
A: Check communication update cycle settings and enable master-slave control mode. Adjust speed synchronization compensation to offset speed deviations caused by load differences. Verify proper installation of terminal resistors on the PROFINET bus.
Q: The inverter is used for four-quadrant port container cranes. The energy recovery effect during braking is poor, and the grid-side current harmonic content exceeds the standard (THDi>15%). How to optimize?
A: Install a low-harmonic module to achieve THDi≤3%. Adjust regenerative energy threshold parameters and optimize feedback unit firing angles to ensure efficient energy recovery to the grid instead of consumption via braking resistors.
Q: When the ATV900 controls a mill, it reports "Overheating Fault (OH)" after several hours of operation. The ambient temperature is normal and the cooling fan is running. What is the problem?
A: Check for dust clogging in heat sinks and ensure proper installation spacing. Reduce carrier frequency to lower inverter self-heating and switch to heavy-duty overload protection curve. Verify motor bearings for wear that may increase inverter load.
