Installation Guide

• Mount the drive vertically on a flat surface. Keep clearance for airflow above and below.
• Connect mains to L1/L2/L3 and motor to U/V/W. Use shielded cable for EMC compliance.

Manager’s Insight

This drive is a solid choice for retrofits and spare parts. Its integrated brake chopper saves panel space. The dual communication slots give engineers freedom to adapt to different plant networks. However, plan for the i950 migration path if long-term availability matters. The 1.8x overload for 60 seconds handles tough starts without oversizing. Keep the 8 kHz default for low noise; switch to 4 kHz only if derating is acceptable.

Expert Review

I have commissioned several 8200 vector drives. The E82EV302-4C is predictable and robust. Motor auto-tuning is fast. The built-in EMC filter cuts wiring time. One weak point: the serial port uses a non-standard connector, so keep an adapter handy. The migration to i950 is real but needs parameter mapping. For new projects, consider the i950. For existing 8200 vector systems, this unit is a reliable replacement.

Ideal Applications and Equipment

• Conveyor systems with frequent starts and stops.
• Packaging machines requiring precise speed control.
• Material handling equipment with dynamic braking needs.
• Fans and pumps in building automation.
• Textile machinery with variable speed demands.
• Retrofits of older 8200 vector installations.

FAQ

• Q: Can this drive run a 3.0 kW motor on 400 V?
  A: Yes. The rated output is 7.3 A at 8 kHz. Check motor current does not exceed this value.
• Q: Does it have a built-in brake chopper?
  A: Yes. The integrated chopper handles up to 11 kW. Connect an external brake resistor for energy dissipation.
• Q: What fieldbus options are available?
  A: Plug-in modules support PROFIBUS DP, CANopen, DeviceNet, INTERBUS, and AS-Interface. Two slots are available.
• Q: How do I migrate to a newer Lenze drive?
  A: Lenze i950 emulates 8200 vector behavior. Use the i950 PROFIBUS module and L_ICIP library. No drop-in code match exists.
• Q: What is the shipping time?
  A: We ship within 12–24 hours. Express carriers are FedEx, UPS, and DHL.
• Q: Is technical support available?
  A: Contact our team at sales@powergearx.com or +86 18030005825 (WhatsApp).
• Q: Can I use this drive at 50 °C ambient?
  A: Yes, but derate output by 2.5% per °C above +40 °C. At 50 °C, reduce continuous current by 25%.
• Q: What is the warranty period?
  A: 12 months from the shipment date. Covers manufacturing defects only.

Buying Guide

• Verify your motor current. The 7.3 A rated output suits most 3.0 kW 4-pole motors.
• Check your fieldbus needs. Add the correct plug-in module before ordering.
• Confirm the ambient temperature. Use derating if above +40 °C.
• Plan for braking. Choose an external resistor if high inertia loads are present.
• Consider the i950 path for new designs. This 8200 vector unit is best for spares or existing systems.
