Frequently Asked Questions
Q1: I'm in North America, where the local power grid is 3-phase
480V/60Hz. Can this inverter be used directly?
No, you cannot connect it directly! The 380V model has a voltage
range of 380V±15%. Connecting to 480V will damage the internal IGBT
module. Use a step-down transformer or confirm availability of a
480V-compatible model. The inverter automatically adapts to 50/60Hz
frequency.
Q2: Installed in a chemical fiber factory with heavy dust, the
inverter often reports an "overheating" fault. How to fix it?
Clean cooling fins and fan with compressed air every 2-4 weeks.
Ensure proper ventilation with 20cm space above/below and 10cm
left/right. Consider adding a dust cover or external cooling fan
for long-term high-dust environments.
Q3: During commissioning, the motor speed fluctuates and makes a
buzzing sound. What's the problem?
Likely incorrect motor parameters or cable issues. Re-enter motor
parameters from the nameplate. For cables longer than 30 meters,
use shielded cable or add an output reactor to reduce harmonic
interference.
Q4: I want to connect the inverter to the factory's PROFIBUS-DP
control system but can't find the corresponding communication
interface. What should I do?
PROFIBUS-DP is an optional function requiring a separate
communication expansion card. Purchase the compliant version,
install with power off, enable the protocol in parameters, and
confirm compatibility with your distributor.
Q5: The inverter suddenly trips and displays "overcurrent". I
checked the lines and found no short circuit. How to troubleshoot?
Check acceleration/deceleration time settings (increase to 5-10
seconds for high-inertia loads). Verify power supply voltage
stability. Check for mechanical issues like stuck motor bearings.
Add input reactor if voltage fluctuations exceed ±15%.
Q6: I forgot to ground the inverter during installation. Can I use
it temporarily without grounding? What are the risks?
Absolutely not! Without proper grounding, the inverter may trigger
faults, create safety hazards, cause electrical interference, and
violate safety standards. Use separate grounding with resistance
less than 4Ω and wire cross-section not less than 2.5mm².
Q7: Used in high-temperature regions where ambient temperature
often exceeds 50℃, the inverter shuts down automatically. How to
handle it?
Install in cool, ventilated locations away from direct sunlight.
Clean cooling systems regularly. Consider adding external cooling
or using a larger inverter for derating. Contact distributor for
high-temperature customized models if needed.
Q8: Can one inverter control two motors? I want to link multiple
motors together.
Not recommended. Use one inverter per motor to prevent overload and
damage. For multi-motor synchronization, use individual inverters
with communication protocols or dedicated multi-motor control
models.
Q9: The inverter needs repair due to malfunction. Are there repair
centers overseas? How long is the repair cycle?
Delta has authorized repair centers in major industrial regions
worldwide. Minor repairs take 3-7 days locally, while complex
repairs requiring factory service may take 1-4 weeks depending on
location.
