P2-38 Mains loss stop control

The control behavior of the inverter as response to a power failure while the inverter is enabled.

  • 0: The inverter attempts to continue operation by recovering energy from the motor under load. If the power failure lasts only briefly and if sufficient energy can be recovered before control electronics shuts down, the inverter will restart as soon as the power supply is resumed.
  • 1: The inverter immediately disables the output to the motor resulting in the load coasting to a stop or freewheeling. If you use this setting for loads with a high inertia, it might be necessary to activate the flying start function (P2-26).
  • 2: The inverter stops along the rapid stop ramp set in P2-25.
  • 3: DC bus supply, if the inverter is supplied directly via the DC+ and DC-terminal, the power failure detection can be deactivated with this function.
