Frequently Asked Questions
Q: When using the ATV340 to drive a fan, it reports an overcurrent
fault as soon as it starts. What's going on?
A: This is most likely caused by negative pressure in the fan's
operating environment. Enable the inverter's flying start function
and verify motor wiring configuration (star vs delta connection),
as incorrect wiring can trigger overcurrent faults.
Q: When buying the ATV340, how do I choose between models with "E"
and without "E"? Will a wrong choice have a big impact?
A: Models with "E" include integrated Ethernet functionality, while
non-E models support basic communication protocols. For smart
production lines requiring centralized remote control, E models are
essential. For standalone equipment like small fans or pumps, non-E
models provide cost-effective solutions.
Q: The ATV340 makes a lot of noise when driving the motor.
Adjusting the motor speed didn't help—any solutions?
A: First, adjust skip frequency parameters to address resonance
issues. If unresolved, increase switching frequency and verify
motor parameters match nameplate specifications. Perform motor
auto-tuning and consider adding output-side filters to smooth
current waveform and reduce noise.
Q: We purchased the ATV340 for hoisting equipment, but it
frequently reports a "load movement error" during use. How to fix
this?
A: Inspect brake circuit wiring and check for brake wear/aging.
Enable load movement detection in inverter parameters and adjust
torque threshold and load holding time. Verify transmission
components (couplings, gears) for looseness that could cause
unexpected load movement.
Q: If the ATV340 breaks down later, is it easy to buy parts and
repair it myself?
A: Limited user-serviceable parts are available (cooling fans).
Core components like Ethernet boards require professional
installation by Schneider-authorized technicians. For most repairs,
send equipment to authorized Schneider service centers.
