官方故障排除步骤

Message value: Parameter: %1 Drive object: A_INF, B_INF, S_INF, SERVO, TM41, VECTOR Reaction: NONE Acknowledge: IMMEDIATELY Cause: A changeover of units was initiated. Possible causes for the violation of a parameter limit are: - when rounding off a parameter corresponding to its decimal places, the steady-state minimum or maximum limit was violated. - inaccuracies for the data type "Floating Point". In these cases, when the minimum limit is violat ed then the parameter value is rounded up and when the maximum limited is violated the parameter value is rounded down. Fault value (r0949, interpret decimal): Diagnostics parameter r9451 to display all parameters whose value had to be adapted. See also: p0100 (IEC/NEMA mot stds), p0349 (Syste m of units, motor equivalent circuit diagram data), p0505 (Selecting the system of units ), p0595 (Selecting technological units) Remedy: Check the adapted parameter values and if required correct.
