8400 protec

The 8400 protec frequency inverter is suitable for decentralized wall mounting and features simple plug-in technology. The decentralized arrangement significantly shortens the length of the motor cables. This enables even complex machines to be structured clearly.
The requirements of the Ecodesign Directive, Standard EN IEC 61800-9-2, are met.
Application areas: Turntables and scissor lift tables (intralogistics), monorail overhead conveyors (automotive industry), ...

Highlights

  • Easy commissioning with plug technology (plug and drive)
  • LED display and status LEDs
  • High protection class IP65

Error codes
Fault ID: 12816
Hex: 0x3210
Description: Fault - DC bus overvoltage
Keypad display: DC Bus OV
Cause Remedy Severity/response

DC-bus voltage has exceeded the error threshold for overvoltage due to a too high braking energy or a too high mains voltage. The error threshold (display in 0x2540:006 (P208.06) results from the setting of the rated mains voltage in 0x2540:001 (P208.01).

Reduce dynamic performance of the load profile.

Check mains voltage.

Check settings for brake energy
management.

0x2541:001 (P706.01) = [0]: Connect brake resistor to the power unit and activate the integrated brake chopper
