NC is in a reset stateIn this case, RESET is also displayed on the status display. Check it usingthe procedure of 1 above.(4)Jog feed rate setting (Parameter) is not correct.1423 Jog feedrate per axis1402#7(5)Manual feed per revolution is selected ( T series)This funciton feeds an axis synchronized with spindle rotation andwhether this function is used or not is selected by the followingparameter:#6 #5 #4JRV#3 #2 #1 #0#4 (JRV) 0 : Jog feed is of feed per minute1 : Jog feed is of feed per revolution(a) When parameter JRV is set to 1, feed rate of the axis is calculatedby synchronizing with rotation of the spindle. Therefore, rotate thespindle.(b) If the axis does not move even when the spindle is rotated, checkthe detector of the spindle (position coder) and the cable betweenthe position coder and the CNC if it is short–circuited orungrounded.Refer to 2.4 for connection diagram.309
