E136 Broken wire, AL signal of E21A feedback.
E236 Broken wire, AL signal of E21B feedback.
E336 Broken wire, AL signal of E21C feedback.
E436 Broken wire, AL signal of E21D feedback.
For differential TTL feedback. The AL and/or /AL signal wire may be broken or disconnected. Check the
connection. Check the level of the signals provided by the feedback device.
E137 Received alarm signal at E21A feedback.
E237 Received alarm signal at E21B feedback.
E337 Received alarm signal at E21C feedback.
E437 Received alarm signal at E21D feedback.
The encoder has generated a signal alarm due to its poor performance. Check the encoder
documentation to determine the source of (reason for) the alarm. It could also be a false positive due
to poor connection.
E138 Amplitude alarm at E21A feedback.
E238 Amplitude alarm at E21B feedback.
E338 Amplitude alarm at E21C feedback.
E438 Amplitude alarm at E21D feedback.
Too much damping or saturation of A and/or B signals. The wiring, the feedback device or the feedback
of the Sercos counter may have some problem.Check the condition (shape) of the cable, of the
connection or of the feedback device. If the problem persists, contact Fagor Automation.
E140 Feedback frequency too high at E21A feedback.
E240 Feedback frequency too high at E21B feedback.
E340 Feedback frequency too high at E21C feedback.
E440 Feedback frequency too high at E21D feedback.
The axis moving speed exceeds the sampling capability of the Sercos counter hardware for this type
of encoder signal. Decrease the maximum axis moving speed.
E141 Wrong distance between I0, E21A feedback.
E241 Wrong distance between I0, E21B feedback.
E341 Wrong distance between I0, E21C feedback.
E441 Wrong distance between I0, E21D feedback.
Error indicating lack of repeatability of the I0 signal in each encoder revolution. Some pulses are being
lost and/or the measurement provided by the feedback device is wrong.
Resettable error. Check that the connection and the wiring are correct. Check that the number of pulses
allowed as error margin is not too low. Check that the value of CNC parameter REFPULSE is correct.
Contact Fagor Automation. If the error persists, it may be because the feedback device is defective.
E142 Over-current or short-circuit at E21Afeedback.
E242 Over-current or short-circuit at E21B feedback.
E342 Over-current or short-circuit at E21C feedback.
E442 Over-current or short-circuit at E21D feedback.
Either a short-circuit has occurred or the feedback device is over-supplied.
Check cables and connections.
E143 Communication error at E21A feedback. Wrong CRC.
E243 Communication error at E21B feedback. Wrong CRC.
E343 Communication error at E21C feedback. Wrong CRC.
E443 Communication error at E21D feedback. Wrong CRC.
Error reading absolute position value; wrong CRC.
Check the cable and connection of the linear or rotary encoder. Check that the parameters of the
feedback device have been set correctly. If the problem persists, contact Fagor Automation.
E144 Communication error at E21A feedback. Acknowledge not received.
E244 Communication error at E21B feedback. Acknowledge not received.
E344 Communication error at E21C feedback. Acknowledge not received.
E443 Communication error at E21D feedback. Acknowledge not received.
Error reading absolute position value; acknowledge not received.
Check the cable and connection of the feedback device. The error could be due to a problem at the
feedback device. If the problem persists, contact Fagor Automation.
