Group 55: FSM: Actual value evaluation 1
55-0
FSM: no actual speed /
position value available or
standstill for > 24 hrs
Cause:
• Subsequent error when a position encoder fails.
• Safety function SSF, SS1, SS2 or SOS requested and actual rotational
speed value is not valid.
Measure:
Check the function of the position encoder(s) (see following error).
55-1
FSM: SINCOS-Geber [X2B] -
signal error
▪ Vector length sin²+cos² is outside the permissible range.
▪ The amplitude of one of the two signals is outside the permissible range.
▪ Offset between analogue and digital signal is greater than 1 quadrant
Measure:
▪ 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 / shield).
▪ Check the supply voltage for the position encoder.
▪ Check the motor cable / shield connection on motor and drive side. EMC
malfunctions may trigger the error.
55-2
FSM: SINCOS encoder
[X2B] - standstill > 24 hrs
Cause:
Input signals of the SinCos encoder have not changed by a minimum amount for
24 hours (when safety function is requested).
Measure:
Terminate SS2 or SOS and move axle at least once during this time.
55-3
FSM: Resolver [X2A] -signal
error
Cause:
▪ Vector length sin²+cos² is outside the permissible range.
▪ The amplitude of one of the two signals is outside the permissible range.
▪ Input signal is static (same values to right and left of maximum).
Measure:
▪ Check the resolver.
▪ Check the connection wiring (broken wire, short between two signals or
signal / shield).
▪ Check for a failure of the exciting current.
▪ Check the motor and encoder cable / shield connection on motor and drive
side. EMC malfunctions can trigger the error.
55-7
FSM: other encoder [X2B] -
Faulty angle information
Cause:
▪ "Angle faulty” message is sent from servo drive when status lasts for longer
than the allowed time.
▪ Encoder at X2B is analysed by the servo drive
▪ Encoder is defective.
Measure:
▪ Check the position encoder at X2B.
▪ Check the connection wiring (broken wire, short between two signals or
signal / shield).
▪ Check the supply voltage for the EnDat encoder.
▪ Check the motor cable / shield connection on motor and drive side. EMC
malfunctions may trigger the error.
