| Signal level over-/undershot |
See page Supervision of Sine Cosine Encoders. The monitoring can be switched off with CPHASE 2 . | See page Supervision of Sine Cosine Encoders. | ||
| Linear measuring system used | Shielding of the feedback cable. see page Sporadic error message F04 with linear measuring systems | Shielding of the feedback cable. see page Sporadic error message F04 with linear measuring systems | ||
| supply current too low (Renishaw measuring system) |
Resistor might be required (supply line) |

| Faulty data in the encoder |
This error occurs with new encoders, that have never been initialized |
This error occurs with new encoders, that have never been initialized Solution: Initialize the data with the command HSAVE (terminal screen). |

Extended error message S300 / S700
a second error message with a small "i" (ERRCODE2) is displayed in the display, which has the following meaning:
| i 16 | Error while reading the BISS position in regsiter mode. |
| i 18 | BISS communication fault |
| i 22 | Reading the encoder data via slow data access was not possible (communication problem with the Encoder) |
| i 23 | Reading the encoder data via fast data access was not possible (communication problem with the Encoder) |
| i 28 | The plugged in option card does not match with the software version of the drive. |
| i 53 | min. resolver amplitude (threshold) undershot |
| i 54 | max. amplitude jump of the resolver signals |
| i 55 | phase deviation between sine/cosine of the resolver |
