Encoder supply
The encoder supply voltage is below the permitted limit.
Vss Sin/Cos
The voltage value for the Sin/Cos track violates the configured limit values.
→ See registers SinCosVssMin and SinCosVssMax.
Position error
The position value determined violates internal requirements.
HIPERFACE communication
Communication error on the HIPERFACE interface (RS485)
→ See register HfErrorCode.
HIPERFACE reference warning
The digital interface provides an absolute position value that can be used to accurately describe the axis position.
The position value is homed to this absolute value at the beginning of a measurement. The analog interface can be
used to incrementally sample changes that occur very rapidly. This enables the module to continue sampling the
position value at a high resolution. Both the analog and the digital signal are sampled cyclically. If the value read
incrementally deviates from the absolute value during operation, then the warning is generated and the position
must be homed again.
