官方故障排除步骤
Message value: %1 Drive object: A_INF, S_INF Reaction: OFF2 (NONE, OFF1) Acknowledge: IMMEDIATELY (POWER ON) Cause: The RMS line supply voltage Vrms was so high when powering up that controlled operation is not possible without exceeding the permissible ma ximum voltage in the DC link (p0280). Fault condition: Vrms * 1.5 > p0280. Fault value (r0949, floating point): Lowest possible controlled DC link voltage fo r the line supply voltage presently connected. See also: p0280 (DC link voltage maximum steady-state) Remedy: - check the line supply voltage - check the maximum DC link voltage and if required, increase (p0280). - check the line supply voltage and compare with the actual line supply voltage (p0210). - check whether the power unit is dimension ed for the line supply vo ltage actually being used. See also: p0210, p0280
