官方故障排除步驟
Message value: Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: During encoder identification (s ervicing) with p0400 = 10100, the encoder could not be identified. Either the wrong encoder has been installed or no encoder has been installed, the wrong encoder cable has been connected or no encoder cable has been connected, or the DRIVE-CLiQ component has not been connected to DRIVE-CLiQ. Note: Encoder identification must be supported by the encoder and is possible in the following cases: Encoder with EnDat interface, motor with DRIVE-CLiQ. Remedy: - Check and, if necessary, connec t the encoder and/or encoder cable. - Check and, if necessary, est ablish the DRIVE-CLiQ connection. - In the case of encoders that cannot be identified (e.g. encoders without EnDat interface), the correct encoder type must be entered in p0400.
