Frequently Asked Questions
Q1: A small European machine tool factory uses the ACS355 to drive a customized processing machine tool. After connecting to the PLC via PROFIBUS DP, communication disconnections frequently occur. How to solve this?
A: First, check if the bus adapter is firmly inserted—vibrations in industrial production environments often cause loose connections. Second, adjust the communication baud rate from the default 187.5kbps to 9600bps to improve anti-interference capability. Additionally, install 120Ω terminal resistors at both ends of the bus to reduce signal reflection (cable wiring in machine tool factories is relatively long, leading to significant signal attenuation). If disconnections persist, check if power cables and communication cables are laid in parallel—maintain a distance of at least 50cm to avoid electromagnetic interference.
Q2: A Southeast Asian food machinery factory uses the ACS355 to control sauce mixing equipment. During operation, the inverter housing has slight leakage current, and an electroprobe lights up, but the motor runs normally. Is there a safety hazard?
A: Yes, there is a safety hazard! This is mainly caused by poor grounding. Food factories have humid environments, increasing the risk of electric shock. Solutions: Check if the ground cable gauge meets standards (at least the same as the power cable) and if the ground terminal is tightly fastened. Measure the ground resistance—European standards require ≤4Ω, while some Southeast Asian countries require ≤10Ω, ensuring compliance with local regulations. If the inverter is installed on a metal frame, the frame must also be grounded to form an equipotential connection, avoiding electric shock accidents.
Q3: An Indian textile factory uses the ACS355 to drive a winding machine. The motor vibrates at low speeds, resulting in uneven yarn tension. How to debug?
A: The ACS355 defaults to V/F control mode, which has poor low-speed performance. Switch to "Sensorless Vector Control" mode and perform motor auto-tuning (enter motor nameplate parameters) to allow the inverter to accurately match motor characteristics. Meanwhile, adjust the "Low-Speed Torque Compensation" parameter from the default 0 to 5-10% to enhance low-speed operation stability. Additionally, check if the mechanical transmission parts of the winding machine (e.g., gearbox, belt) are worn—mechanical jamming can also cause vibration and requires timely maintenance.
Q4: A small African building materials factory uses the ACS355 to drive a cement transfer pump. The power grid voltage fluctuates heavily, and "undervoltage" faults frequently occur. How to handle this?
A: Enter the parameter menu, switch the "Input Voltage Allowable Range" to "Wide," expanding the undervoltage threshold from 380V to 342V to adapt to grid fluctuations. Second, check if the power cable gauge is too small—building materials factories are often far from transformers, and line loss causes voltage drops at terminals. It is recommended to upgrade the cable gauge (e.g., from 1.5mm² to 2.5mm²). If fluctuations are frequent, install a small voltage stabilizer or UPS to avoid frequent inverter shutdowns affecting production.
Q5: A small North American packaging machinery factory uses the ACS355 to control a customized packaging machine. It requires quick stopping, but even with the inverter's deceleration time set to the shortest, there is obvious inertial coasting. How to solve this?
A: ACS355 models ≤11kW support external braking resistors. After installing a braking resistor, enable the "DC Braking" function in the parameters, setting the braking start frequency to 5Hz and braking time to 3 seconds to quickly consume the motor's inertial energy. If frequent start-stop is not required, an electromagnetic brake can also be installed at the mechanical end, cooperating with the inverter to achieve precise stopping (packaging machines have high requirements for stopping positions, and relying solely on electrical braking may be insufficient).
