Is Your Device Showing These Signs?
Lenze EMB9351-E drives commonly exhibit faults stemming from DC bus overvoltage, often due to regenerative energy during rapid deceleration, necessitating brake resistor inspection or parameter adjustments. IGBT failures are frequent, leading to drive trips and requiring component replacement. Communication errors, particularly on the CAN bus or Ethernet interfaces, demand cable checks and configuration verification. Overcurrent faults indicate motor winding issues or incorrect drive settings, prompting motor insulation testing and drive parameter review. Encoder feedback problems cause erratic motor behavior, mandating encoder cable and signal integrity analysis.
