Hurco MB - I I Twin Arm Tool Changer Error Messages:
The loading of tools and the use of the automatic tool changer on the MB - II is described in the operating instructions section of the Owner’s Manual. These notes describe what happens in case of abnormal operation in terms of tool changer error detection, reporting, and recovery procedures.
The tool changer consists of a carousel for storing tools, a changing station, a dual gripper arm, and shot pins for locking the carousel and the spindle. These are all controlled by a motor, solenoids, and pneumatic valves. Electrical sensors and limit switches are tested by the microcomputer in determining in what state the tool changer is. If, during tool changer operation, the microcomputer detects an incorrect state or state change, an "Emergency Stop" condition will result with the message "TOOL CHANGER ERROR nn." The microcomputer also checks the state of the tool changer before starting the spindle for program execution, and if it is not in its’ home state (arm up, arm contracted, shot pin out) an "Emergency Stop" condition will result with the same message.
In the message "TOOL CHANGER ERROR nn." "nn" is an error code, which indicates the reason for the "Emergency Stop" condition. This two digit error code in almost all cases points to a particular limit switch whose signal was not seen by the microcomputer.
The following is a list of the possible error codes and their meanings. Click on "Error Code" Number or "Scroll Page" for explanation. To return here, click Error Code Number above "Condition."
Error Code: 02 03 06 07 12 13 14 15 16 17 24 25 26 27 40 41 50 62 / 72
63 / 73 64 / 74 65 / 75 67 / 77 68 / 78 69 / 79 80 81 82 83 84 85 86 87 88 89
Errors: Limit switch was not detected.
ERROR CODE: 02
CONDITION: Carousel "shot pin" out (unlocate).
ERROR CODE: 03
CONDITION: Carousel "shot pin" in (locate).
ERROR CODE: 06
CONDITION: Tool pot forward. (into changing station)
ERROR CODE: 07
CONDITION: Tool pot back.
ERROR CODE: 12
CONDITION: Arm " CW ."
ERROR CODE: 13
CONDITION: Arm "CCW."
ERROR CODE: 14
CONDITION: Arm up.
ERROR CODE: 15
CONDITION: Arm down.
ERROR CODE: 16
CONDITION: Arm extend.
ERROR CODE: 17
CONDITION: Arm contract.
ERROR CODE: 24
CONDITION: Spindle "shot pin" out.
ERROR CODE: 25
CONDITION: Spindle "shot pin" in.
ERROR CODE: 26
CONDITION: Spindle unclamp.
ERROR CODE: 27
CONDITION: Spindle clamp.
ERROR CODE: 40
CONDITION: Carousel in position.
ERROR CODE: 41
CONDITION: Carousel station clamp.
ERROR CODE: 50
CONDITION: No error. This code is used after a recovery procedure is completed to allow the operator to verify the "CUR TOOL" value in "DATA BLOCK 0."
Errors: Carousel operation.
If one of these failures occurs while the carousel is rotating at the same time as part program operation, the carousel will stop but the milling operation will not be interrupted. The error message will be displayed when the mill stops for the next tool change.
ERROR CODE: 62 / 72
CONDITION: Carousel "shot pin out" (while putting last tool away).
ERROR CODE: 63 / 73
CONDITION: In position (or not rotating) (while putting last tool away).
ERROR CODE: 64 / 74
CONDITION: Carousel "shot pin in" (while putting last tool away).
ERROR CODE: 65 / 75
CONDITION: "Tool pot back" (while putting last tool away).
ERROR CODE: 67 / 77
CONDITION: Carousel "shot pin out" (while fetching next tool).
ERROR CODE: 68 / 78
CONDITION: In position (or not rotating) (while fetching next tool).
ERROR CODE: 69 / 79
CONDITION: Non-sequential tool position code. *
* As the carousel rotates from one tool slot to another, the detection of a non- sequential tool position number indicates a possible failure in the tool position code sensors.
Errors: Invalid limit switch states that prevent the spindle from starting or the head from moving.
ERROR CODE: 80
CONDITION: Spindle "shot pin out" not detected.
ERROR CODE: 81
CONDITION: Both spindle "shot pin in / out" detected.
ERROR CODE: 82
CONDITION: "Arm up" not detected.
ERROR CODE: 83
CONDITION: Both "arm up / down detected.
ERROR CODE: 84
CONDITION: Arm contract not detected.
ERROR CODE: 85
CONDITION: Both "arm contract / extend" detected.
ERROR CODE: 86
CONDITION: Both "tool pot forward / back" detected.
ERROR CODE: 87
CONDITION: Both "gear high / low" detected.
ERROR CODE: 88
CONDITION: Both carousel "shot pin in / out" detected.
ERROR CODE: 89
CONDITION: Both "spindle clamp / unclamp" detected.
Recovery Procedures:
In most cases the above error messages will be caused by a mechanical failure such as a tool changer component jamming or an electrical failure in a limit switch or sensor. In such cases, the problem should be investigated and reported or fixed before continuing to use the mill. In a few cases the tool changer error will be caused by an operator error. The most common example of an operator induced error is an incorrect "CUR TOOL" parameter in "DATA BLOCK 0." If this happens, the tool changer will attempt to put a tool pot back into an occupied slot.
Before describing how to recover from tool changer problems, certain facts will be reviewed.
The correct carousel and tool configurations are as follows. If there is no tool in the spindle, then slot 0 is empty. If there is a tool in the spindle then slot (= tool in spindle) is empty and slot 0 has an empty pot. |
