Siemens F31138

What the Fault Means

Fault: Encoder 1: Internal error when determining multiturn information

Likely causes

• A position determination fault has occurred in the DRIVE-CLiQ encoder
• Fault value (r0949, interpret binary): yyxxxxxx hex: yy = encoder version, xxxxxx = bit coding of the fault cause For yy = 08 hex (bit 27 = 1), the following bit definition applies: Bit 1: Signal monitoring (sin/cos)
• Bit 8: F1 (safety status display) fault position word 1
• Bit 9: F2 (safety status display) fault position word 2

Solution and Safe First Checks

1. determine the detailed cause of the fault using the fault value.
2. if required, replace the DRIVE-CLiQ encoder.

Safety: do not work inside the panel without isolating the power; if unsure, consult a qualified technician.
