– Subsequent error when a position encoder fails.
– Safety function SSF, SS1, SS2 or SOS requested and actual
rotational speed value is not valid.
• Check the function of the position encoder(s) (see following
error).
– Vector length sin²+cos² is outside the permissible range.
– The amplitude of one of the two signals is outside the permiss­
ible range.
– Offset between analogue and digital signal is greater than 1
quadrant.
Error may occur with SIN/COS and Hiperface encoders.
• Check the position encoder.
• Check the connection wiring (broken wire, short between two
signals or signal / screening).
• Check the supply voltage for the position encoder.
• Check the motor cable / screening on motor and drive side –
EMC malfunctions may trigger the error.
– Input signals of the SinCos encoder have not changed by a minim­
um amount for 24 hours (when safety function is requested).
• Terminate SS2 or SOS and move axle once during this time.
– Vector length sin²+cos² is outside the permissible range.
– The amplitude of one of the two signals is outside the permiss­
ible range.
– Input signal is static (same values to right and left of maximum).
• Check the resolver.
• Check the connection wiring (broken wire, short between two
signals or signal / screening).
• Check for a failure of the primary radiator signal
• Check the motor and encoder cable / screening on motor and
drive side. EMC malfunctions can trigger the error.
