官方故障排除步骤
configured %1 [Cause of error] It was configured so that both only the EnDat 2.2 position encoder and only the EnDat 2.2 shaft speed encoder are to be used for functional safety. This is not possible. [Error correction] - Check the entry in Machine Parameter CfgAxisSafety-encoderForSafety: It must either be "speedAndPosEncoder", "speedEncoder" or "posEncoder". - Special settings for single-encoder systems with EnDat 2.2 FS encoders: Set "posEncoder" if only the position encoder is to be used for functional safety or set "speedEncoder" if only the shaft speed encoder is to be used for functional safety - Standard setting: Set "speedAndPosEncoder" if you want to configure a normal dual-encoder system or if the affected axis is run in functional safety with only one encoder (single-encoder safety).
