The axis has exceeded the admitted amount of following error set by machine parameters (MAXFLWE, MINFLWE, FEDYNFAC, ESTDELAY). It may be because the axis has not been adjusted properly, because the axis has not been enabled, because there has been a failure at the motor, at the drive, in the feedback system and/or in the mechanics.

Check the machine parameters, the axis adjustment, the connections, the status of the drive and motor-feedback system.
