Error message
Meaning of the error message
Measures
Main
index
Sub index
Action:
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.
2
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).
Action:
Terminate SS2 or SOS and move axle at least
once during this time.
3
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).
Action: 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.
7
Other encoder [X2B] - Faulty angle
information
Cause: “Angle faulty” message is sent from basic device
when status lasts for longer than the allowed
time.
Encoder at X2B is analysed by the basic device.
Encoder is faulty.
