Frequently Asked Questions
Purchase & Ordering
Q: Can I use the same order number for EU and US markets? Do certifications differ?
A: Order numbers vary by region—US models require UL/cUL certification while EU models need CE marking. Specify your target market when ordering. Core parameters remain the same with certification-related component adjustments.
Q: Do I need to buy additional accessories separately?
A: Base unit includes integrated EMC Class A filter and basic wiring terminals. Optional accessories include local language operator panels, brake resistors for frequent braking, and wireless commissioning modules.
Installation & Wiring
Q: The inverter gets overheated during side-by-side installation—what's wrong?
A: Ensure minimum gap specifications (FSA/FSD: 50mm; FSF: 100mm) between units. Overheating causes include insufficient gaps, poor cabinet ventilation, or ambient temperatures exceeding 40°C requiring derating.
Q: Why does the inverter display an "EMC fault" after wiring? (North American users)
A: Typically caused by incorrect grounding or unshielded cables. Ensure dedicated ground connection (resistance ≤4Ω), use shielded twisted-pair motor cables (length ≤50m), and maintain 300mm separation from power cables.
Q: Can the inverter be installed outdoors?
A: IP20 rating requires indoor cabinet installation. For outdoor use, employ weatherproof cabinet (IP54+) with sunshade and heater for temperatures below 0°C. Never mount directly outdoors.
Commissioning & Operation
Q: The motor doesn't start—how to troubleshoot quickly?
A: Check run command reception via BOP-2 manual start, verify motor wiring, confirm parameter P0731 setting, or reset to factory defaults if settings were modified incorrectly.
Q: How to copy parameters from one inverter to multiple units?
A: Use SD card method: Save parameters from master inverter (P0010=10), then load to slave units (P0010=11). Ensure same frame size and power rating for all units.
Q: The inverter saves energy, but the motor makes noise at low speeds—why?
A: Normal for sensorless vector control. Reduce noise by switching to V/f ECO mode for fans/pumps, increasing low-speed damping parameter for heavy loads, or checking motor bearing condition.
Key Selection Guidelines: Mainstream specification: 3AC 380-480 V (±10%/-20%), 47-63 Hz. EMC Class A filter compliant with EN 61800-3. Standard PROFINET/ENIP with expandable bus options. STO safety standard with expandable functions. 7 frame sizes support side-by-side mounting without derating.
