Model Specifications
Application Areas General Machinery Manufacturing Core Application Scenarios:
Adaptation Benefits: Supports "Material Conveying" simple macro; 16 preset speeds flexibly match different conveying rhythms. Open-loop torque control prevents motor overload from material jams. Optional IP21/66 protection adapts to dusty/humid workshop environments. Sensorless vector control ensures stable spindle speed (±0.5% accuracy). STO function complies with EN ISO 13849 safety standards. Fluid Control Field (Dedicated for Fans/Pumps) Core Application Scenarios:
Adaptation Benefits: Built-in variable torque control mode for fans with energy-saving mode reduces consumption by over 30%. PID regulation automatically adjusts speed based on air pressure/volume. DC injection quick stop prevents water hammer effect. Common DC bus design reduces reactive power loss in multi-pump systems. Packaging and Printing Field Core Application Scenarios:
Adaptation Benefits: Integrated PLC function simplifies external controllers and reduces wiring. Inching operation facilitates equipment debugging. 4 parameter group switching stores operating parameters for different specifications. Synchronous motor control ensures speed synchronization between printing rollers. Hoisting and Lifting Field Core Application Scenarios:
Adaptation Benefits: "Hoisting" simple macro includes overload protection and braking logic. SLS (Safe Limited Speed) and SS1 (Safe Stop 1) comply with hoisting equipment safety standards. Open-loop control for PMSM adapts to high-efficiency hoisting motors, reducing energy consumption. Food and Beverage Field Core Application Scenarios:
Adaptation Benefits: IP66 high protection level (UL Type 4X) withstands washing and disinfection, complying with food industry hygiene standards. Fanless design avoids dust accumulation and reduces cleaning dead ends. Automatic restart function meets continuous production line operation needs. Frequently Asked Questions Selection and Adaptation Q: For a 380V three-phase 5.5kW centrifugal fan, which ATV320 model
is most suitable? What parameters need attention? A: The ATV320U55N4C is preferred. The power code "U55" corresponds to 5.5kW, and voltage code "N" suits 380-500V three-phase systems. Key checks: confirm support for "fan variable torque" control mode, and for outdoor applications, select IP66 protection model (suffix "W") to prevent rainwater damage. Q: Can the ATV320 drive a permanent magnet synchronous motor (PMSM)
directly? What parameters need adjustment? A: Yes, with two parameter adjustments: change "motor type" to "PMSM" and use "auto-identification" to read motor specifications from nameplate. For food workshops requiring washing, IP66 protection models are mandatory. Q: How to use parameter group switching for frequent specification
changes in packaging machines? A: Store parameters for each specification in separate groups (4 available). Switch between groups via external terminals or panel buttons when changing specifications. Ensure motor is stopped before switching to avoid overload protection triggers. Installation and Wiring Q: What spacing is required for vertical stacking of book-type
ATV320 models? Will heat dissipation be affected? A: Maintain minimum 15cm vertical and 5cm horizontal spacing. Close stacking causes heat accumulation - 3 stacked units at 40°C reduces maximum temperature tolerance to 45°C. Recommend adding cabinet exhaust fan for auxiliary heat dissipation. Q: Why is the analog signal unstable when connecting sensors to AI1
port? A: Likely wiring issues: separate analog from power wires to avoid interference; ensure common ground between sensor and inverter power; adjust "analog input filter time" to 0.5s in industrial environments for signal stability. Q: How to wire external emergency stop button for STO function? Is
additional safety relay needed? A: Wire emergency stop directly to STO terminals (S1 and S2); no additional relay required. Use twisted shielded wires under 5 meters length. Test: emergency stop should immediately cut motor torque and display "STO Activated". Operation and Fault Resolution Q: Fan frequently reports overtemperature fault (OH) at 35°C
ambient. How to resolve? A: Clean dust from heat dissipation holes with compressed air. Adjust "derating temperature point" to 45°C to allow early derated operation (10% power reduction). Confirm fan load doesn't exceed inverter rated torque. Q: Why does DC injection quick stop occasionally report DC
overvoltage (OU) for pump loads? A: Motor kinetic energy converts to electrical energy, raising DC bus voltage. Solutions: shorten "DC injection time" to 0.2s, or use common DC bus design (with ATV Regen) for multi-pump systems to consume excess energy. Q: No display or power light after power-on. Is inverter faulty?
How to troubleshoot? A: Check input power voltage (single-phase models prone to wrong wiring). If power normal, internal switching power supply may be faulty. Contact after-sales service - do not open cover due to electric shock risk. Maintenance and Service Life Q: What daily maintenance is required for fanless ATV320? Component
replacement frequency? A: Monthly: vacuum dust from heat dissipation holes. Semi-annually: check terminal connections. Component life: electrolytic capacitors ~5 years (halves with every 10°C temperature increase); IGBT modules ~8 years (reduces to 3-4 years with frequent overloading). Annual insulation testing recommended. Q: Is automatic restart safe when power recovers after blackout?
How to set reasonably? A: Add 3-5 second "start delay after power recovery" and bind to safety door signal - restart only when door closed. Not recommended for hoisting equipment to prevent sudden falling; use SS1 function instead. |
