Working Principle

Advantage Highlights

1. Bus-powered design eliminates separate external power adapter requirement for field commissioning
2. Handheld portable form factor allows remote local control without cabinet door disassembly
3. Full parameter backup/restore accelerates mass drive configuration on production lines
4. Dedicated fault history logging simplifies drive failure root-cause diagnostic analysis
5. Exclusive matching pinout optimized for 21/22/23 kW MOVITRAC 31C power frame inverters
6. Low weight compact construction reduces technician field service equipment carrying load

Applicable Industries

Installation Requirements

1. Direct plug-in connection exclusively to MOVITRAC 31C series 21/22/23 kW inverter front 8-pin service port
2. Maximum service cable extension length: 3 m factory-specified shielded connection cable
3. Avoid physical bending of circular connector cable below 50 mm minimum bend radius
4. Do not operate unit in ambient temperatures exceeding 50 °C continuous handheld usage

Usage Notes

1. Disconnect panel before executing high-voltage insulation resistance testing on inverter motor terminals
2. Store unit in protective foam carrying case when not in field service to prevent LCD screen scratch damage
3. Wipe membrane button panel with dry microfiber cloth only; avoid liquid cleaning solvents
4. Parameter backup files stored on panel volatile memory are lost after full disconnection power cycle
5. Do not connect FBG31C-08 to incompatible SEW drive models (non-31C series inverters cause communication failure)
