Debugging and operation

(1) Debugging method

Debugging Tools/Carrier Core Processes Applicable Scenarios

DBG11A panel, DBG11A button panel, connect to the TERMINAL slot → enter the startup menu → input motor parameters → calculate and save on-site quick debugging, without PC scenarios

MOVITOOLS software computer+USS21A adapter installation software → connect RS-232/RS-485 → select motor type → configure parameters → download batch debugging, complex parameter configuration
