  • 1: Startup (inicialización del drive)
  • 2: Not_Ready (voltaje principal apagado)
  • 3: Ready (voltaje principal encendido)
  • 4: Enabled (drive ha recibido comando de marcha)
  • 5: Stopping (drive ha recibido comando de parada y está deteniéndose)
  • 6: Fault_Stop (drive está detenido debido a una falta)
  • 7: Faulted (han ocurrido faltas)
