text: <s>[INST] ultra 3000i E022 fault Summary: drive trips after running awhile.I have an Ultra 3000i indexer drive, will run quite a few cycles then trips E022. this just started on an existing system thats run fine for years. Motor is cold to the touch. no brake in motor. N-3412-2-H00AA. Mechanical gearing seems fine. no drag. Online with ultraware v 1.8 wont let me shut off software protection, as i figure its the default parameters for that motor. any ideas to prove drive,motor or mechanical is the issue??? or how to disable the software protection? [/INST] E022 is Motor Thermal Protection Fault, and it is apparently calculated. It is different than E04, which is motor overtemperature. E04 comes from the motor thermostat on pins R and S of the encoder cable. I do not think you can disable this fault. Are you sure the motion parameters have not changed recently? Did someone change the accel rate without your knowledge, or decrease the time of the move? You do say that it takes quite a few cycles before it trips. After the first fault, does the fault reoccur with increasing frequency? I would check power lead connections from drive to motor for tightness or thermal discoloring. \\n </s>
