公式トラブルシューティング手順
Details When returning to the reference position, the near-point detection limit switch did not stop over the dog, but overran the dog. Remedy Increase the length of the near-point dog. Reduce the reference position return speed. Some ax does not pass Z phase 0002 Details One of the axes did not pass the Z-ph ase during the initial reference position return after the power was turned ON. Remedy Move the encoder one rotation or more in the opposit e direction of the reference position, and repeat ref- erence position return. R-pnt direction illegal 0003 Details When manually returning to the reference position, the retu rn direction differs from t he axis movement direction selected with the AXIS SELECTION key. Remedy The selection of the AXIS SELECTION key's +/- direction is incorrect. The error is canceled by feeding the axis in the correct direction. External interlock axis exists 0004 Details The external interlock function has activated (the input si gnal is "OFF") and one of the axes has entered the interlock state. Remedy As the interlock function has activat ed, release it before resuming operation. Correct the sequence on the machine side. Check for any broken wires in the "interlock" signal line. Internal interlock axis exists 0005 Details The internal interlock state has been entered. The axis with absolute enc oder has been detached. A command for the manual/automatic simultaneous va lid axis was issued fr om the automatic mode. The manual speed command was issued while the "tool length measurement 1" signal is ON. A travel command has been issued to an inclined axis w hose basic axis is in control axis synchronization be- tween part systems. Selected an axis other than the 1st axis when the manual speed command was issued. A travel command has been issued to an axis stopped by the collision detection function. Positioning or interpolation command was issued during the spindle-mode rotary axis control mode. Remedy The servo OFF function is valid, so release it first. An axis that can be removed has been issued, so perform the correct operations. The command is issued in the same direction as the direction where manual skip turned ON, so perform the correct operations. During the manual/automatic simultaneous mode, the axis commanded in the automatic mode became the manual operation axis. Turn OFF the "manual/automatic valid" signal for the commanded axis. Turn ON the power again, and perform absolute position initialization. Turn OFF the "tool length measurement 1" signal to start the program by the manual speed command. Cancel the control axis synchronization be tween part systems, then issue a travel command to the inclined axis. Select the 1st axis of each part system when issuing the manual speed command. Cancel the collision detection alarm. Check the program after cancelling the error by reset. H/W stroke end axis exists 0006 Details The stroke end function has activated (the input signal is "OFF") and one of th e axes is in the stroke end status. Remedy Move the machine manually. Check for any broken wires in the "stroke end" signal line. Check for any limi t switch failure.
