官方故障排除步驟
Message value: %1 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: The value in p0118 produces a dead time of one clock cy cle because it is prior to setpoint availability. A possible cause could be, for example, that the sy stem characteristics no longer match those parameterized after a component has been replaced. Alarm value (r2134, floating point): The minimum value for p0118 where a dead time no longer occurs. Remedy: - set p0118 to a value greater than or equal to the alarm value. - set p0117 to an automatic setting. - check the firmware releases of the components involved.
