Siemens F32118 fault code meaning

Series: G120-CU250S-2

Encoder 2: Speed difference tolerance exceeded

converter

Meaning: When using a HTL/TTL encoder, the speed difference across multiple sampling cycles exceeded the value in p0492. Changes in the measured actual speed are monitored within the current loop sampling period.

Possible causes

Source: SINAMICS G120, Control Unit CU250S-2 P1121

Series: G130-G150

Encoder 2: Speed difference outside the tolerance

converter

Meaning:

Possible causes

Source: G150 P951

Series: S200

Encoder 2: Implausible speed change

servo drive

Meaning: When using the HTL/TTL encoder, the speed change exceeded the value of p0492 for several sampling cycles. The device checks at the current controller sampling interval whether the calculated average actual speed changes.
