官方故障排除步骤
Message value: %1 Drive object: All objects Reaction: OFF2 Acknowledge: POWER ON Cause: Another Sensor Module Integrated (SMI) was found. The reasons could be as follows: 1. A motor with DRIVE-CLiQ (SMI) and another order No. were used as replacement. 2. A Sensor Module Integrated was used as spare part where there is no encoder data and motor data or the incorrect data are present. Fault value (r0949, interpret hexadecimal): The value should be interpreted as follo ws as 8-digit hexadecimal number AAAABBBB: BBBB = Reserved. AAAA = Component number of the component involved. Remedy: Re 1. - restore the factory setting. - carry out the first commissioning. Re 2. - download the SMI data from the back-up (p4690, p4691). - carry out a POWER ON (power off/on) for all components.
