Lenze Inverter EVF9330-EV

To ensure that overseas customers can smoothly replace and put the spare parts into operation, every Lenze Inverter EVF9330-EV that leaves the warehouse is an original and genuine product, with a device protection level of IP20. MaoHui uses DHL Express, FedEx or UPS for expedited delivery, and the transportation time to major industrial areas in Europe, North America, Southeast Asia and the Middle East is usually 3 to 5 working days. After the goods leave the warehouse, we will provide you with the courier tracking number immediately for real-time tracking.

Model parameters

Product features

1. In the low speed running state as low as 0.5Hz, it can still maintain sufficient power output to avoid the device getting stuck when starting with heavy load.

2. The airflow from the fan directly passes over the heat dissipation aluminum sheet and is separated from the internal electronic board area, which can reduce the accumulation of dust from the industrial site on the circuit board.

3. The Lenze Inverter EVF9330-EV can directly expand PROFIBUS-DP, CANopen, Interbus and other bus adapter boards through the front-end slot to achieve high-frequency data communication.

4. It integrates output short-circuit protection, ground fault detection, DC bus overvoltage/undervoltage monitoring, and driver over-temperature protection internally.

Application scenarios

Food and chemical machinery: Liquid/powder mixers, small reaction vessels drives.

Packaging and winding equipment: Semi-automatic packaging machines, high-speed film roll cutting machines.

Material handling systems: Inclined belt conveyors, spiral feeders, automatic material lifting units.

Building materials and woodworking machinery: Small stone polishing machines, multi-head drill axes drives for woodworking.

Environmental protection equipment: Small-flow sewage pumping pumps, industrial exhaust gas extraction fans.

Service Advantages

1. The qualified inventory spare parts sold by Maohui are all guaranteed with a 12-month quality assurance period.

2. The overseas customer service team supports multilingual communication, ensuring a clear response within 2 hours after receiving the purchase inquiry and technical consultation.

3. For urgent orders due to customer factory downtime, we will prioritize testing and arrange for international express delivery on the same day.

FAQ

When "OH" (overheat alarm) appears on the EVF9330-EV at the site, what steps should be taken for troubleshooting?

1. Confirm whether the cooling fan at the bottom of the inverter rotates normally and whether the air duct is blocked by oil or dust. Mao Hui found that a stuck fan is the most common cause of overheating during the inspection.

2. Check whether the temperature in the control cabinet exceeds 45°C, and whether there is at least 100mm heat dissipation spacing up and down the frequency converter.

3. If "OH4" is reported, please check whether the T1/T2 terminal wiring is loose or whether the motor temperature sensor (PTC/KTY) has operated due to the actual overheating of the motor.

In sensorless vector control mode, how can the output torque of the Lenze Inverter EVF9330-EV at low speeds be increased?

Perform motor parameter self-tuning (Auto-tuning): After wiring is completed, use the operation panel to identify the motor parameters statically and have the inverter accurately write in the stator resistance and leakage inductance values of the motor.

Properly fine-tune the low frequency Boost Voltage (Boost Voltage) : If the V/f mode is used, the starting voltage compensation parameter can be appropriately adjusted, but do not set too high.

Freight and Packaging Assurance

To ensure that the precision frequency converter is protected from vibration and moisture during long-distance cross-border transportation, Maohui will completely seal it with anti-static bags, and insert high-density foam lining blocks custom-made according to the size of the frequency converter body around the edges. The outer packaging is made of five-layer thickened hard corrugated cartons, and the outside of the carton is wrapped with multiple layers of waterproof stretch film as a whole. For some equipment, we choose to transport it in boxes. We keep long-term stability with DHL Express, FedEx, UPS, can press the FOB, CIF, DAP, DDP trade terms of delivery, ensure the security of the spare parts, arrive at customer factory.
