Issue Description & Safety Warning

The Siemens SINUMERIK 840D CNC has triggered a critical <location>Project conversion error alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.

Official Troubleshooting Steps

Message value: %1 Drive object: SERVO, VECTOR Reaction: OFF2 (NONE) Acknowledge: IMMEDIATELY Cause: When converting the project of an older firmware version, an error occurred. Fault value (r0949, interpret decimal): Parameter number of the parameter causing the error. For fault value = 600, the following applies: The temperature evaluation is no longer assigned to the power unit but to the encoder evaluation. Notice: Monitoring of the motor temperature is no longer ensured. Remedy: Check the parameter indicated in the fault value and correctly adjust it accordingly. Re fault value = 600: Parameter p0600 must be set to the values 1, 2 or 3 in accordance with the assignment of the internal encoder evaluation to the encoder interface. Value 1 means: The internal encoder evaluation is assigned to the encoder interface 1 via p0187. Value 2 means: The internal encoder evaluation is assigned to the encoder interface 2 via p0188. Value 3 means: The internal encoder evaluation is assigned to the encoder interface 3 via p0189. If necessary, the internal encoder evaluation must be assigned to an encoder interface via parameters p0187, p0188 or p0189 accordingly. - If necessary, upgrade the firmware to a later version.
