代码 207551: <location>Drive encoder: No commutation angle information
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Drive encoder: No commutation angle information 警报。需要由合格的操作员或维修技师立即处理,以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前,请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
Message value: Fault cause: %1, drive data set: %2 Drive object: SERVO, VECTOR Reaction: OFF2 (IASC/DCBRAKE) Acknowledge: IMMEDIATELY (POWER ON) Cause: The commutation angle information is missing. Th is means that synchronous motors cannot be controlled (closed-loop control) Fault value (r0949, interpret decimal): yyyyxxxx dec: yyyy = fault cause, xxxx = drive data set yyyy = 1 dec: The motor encoder used does not s upply an absolute commutation angle. yyyy = 2 dec: The selected ratio of the measuring gear does not match the motor pole pair number. SINAMICS-Alarms Remedy: Re fault cause = 1: - check the encoder parameterization (p0404). - use an encoder with track C/D, EnDat interface of Hall sensors. - use an encoder with sine-wave A/B track for which the motor pole pair number (r0313) is an integer multiple of the encoder pulse number (p0408). - activate the pole position identification routine (p1982 = 1). Re fault cause = 2: - the quotient of the pole pair number divided by the ratio of the measuring gear must be an integer number: (p0314 * p0433) / p0432. Note: For operation with track C/D, this quotient must be less than 8. See also: p0402, p0404, p0432, p0433
