官方故障排除步驟
Message value: Component number: %1, encoder data set: %2 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: IMMEDIATELY Cause: When the position tracking of the measuring gear is configured, the drive/enc oder identifies a maximum possible absolute position actual value (r 0483) that cannot be represented within 32 bits. Maximum value: p0408 * p0412 * 2^p0419 Fault value (r0949, interpret decimal): Low word low byte: Encoder data set number Low word high byte: Component number See also: p0408, p0412, p0419 Remedy: - reduce the fine resolution (p0419). - reduce the multiturn resolution (p0412). See also: p0412 (Measuring gear, rotary absolute gear box, revolutions, virtual), p0419 (Fine resolution absolute value Gx_XIST2 (in bits)) SINAMICS-Alarms
