官方故障排除步骤
Type: Alarm 1 The converter was intentionally powered up in single-phase mode with only AC phase L1-L2 present. Intentional single-phase mode is only detected at the initial application of AC line voltage. Application of 3-phase voltage after the converter has entered single-phase mode results in the single phase alarm becoming a fault. • Verify that only one phase is applied to a drive in single-phase mode.
