21:X4-Wire break A wire break from one or more 
tracks was detected.
• Check the encoder cable

22:AX5000 Acknowledgement for axis swi-
tchover did not occur.
Check the wiring between the inverter and POSISwitch 
AX 5000.
programmed ac-

23:AX5000required A POSISwitch AX 5000 was pro-
jected but not connected.
• Match the projection of your hardware.
• Check the connection of the POSISwitch AX 5000.

24:X120-speed B297, G297 or I297 exceeded for 
the encoder at X120
• Check the connection and shielding of the encoder 
cable.
• Reduce the electromagnetic interference.
• Check the parameterization of B297, G297 or I297.

25:X4-speed B297, G297 or I297 exceeded for 
the encoder at X4
programmed ac-

26:X4-noEnc.found No encoder was found at X4 or a 
wire break was detected at the 
EnDat®/SSI encoder.
• Correct the connection of the encoder.
• Check the encoder cable
• Correct the power supply of the encoder.
• Check the setting of the H00 parameter.

27:X4-AX5000 gef A functional AX 5000 option was 
found at X4 although the incre-
mental encoder or EnDat® en-
coder was parameterized or no 
EnDat® encoder is connected to 
option AX 5000.
• Check the setting of the H00 parameter.
• Check the connection of the encoder at the PO-
SISwitch AX 5000.

28:X4-EnDatfound An EnDat® encoder was detect-
ed at X4 although a different en-
coder was parameterized.
