EXTERNAL FAULT 1 defines how the drive reacts to an external fault signal, with options for disabling or using digital input D11 as the trigger source. The manual's first action is: “0 = NOT SEL – External fault signal is not used. 1 = DI1 – Defines digital input D11 as the external fault input. • Activating the digital input indicates a fault. The drive displays a fault (14, EXT FAULT 1) and the drive coasts to stop. 2...6 = DI2...DI6 – Defines digital input D12...D16 as the external fault input. • See D11 above. -1 = DI1(INV) – Defines an inverted digital input D11 as the external fault input. • De-activating the digital input indicates a fault. The drive displays a fault (14, EXT FAULT 1) and the drive coasts to stop. -2...-6 = DI2(INV)...DI6(INV) – Defines an inverted digital input D12...D16 as the external fault input. • See D11(INV) above.”
