1. First check whether "parameter" 1423 (JOG feed speed of each axis) is set correctly.
2. Check whether there is "I" or "L" in front of the coordinate axis on the "Position Page".
1. If all coordinate axes have "I" in front of them, then search for G8.0 in the ladder diagram; if only some coordinate axes have "I", then search for G130.0~G130.4.
2. If all coordinate axes have "L" in front of them, then search for G44.1 in the ladder diagram; if only some coordinate axes have "L", then search for G108.0~G108.4.
3. Through the found G signal, see which of the previous driving conditions are not met, follow the clues, connect the unsatisfied driving conditions normally, and solve the fault.
The above G signal is briefly explained here. For details, please refer to the "Connection Manual Functions".
1. G8.0: All axis interlock signal *IT, a signal used to prohibit the movement of all feed axes, normal is 1, abnormal is 0, the control logic is the same as G8.4.
2. G130.0~G130.4: The interlock signals *IT1~*IT5 of each axis are used to independently prohibit the movement of a certain feed axis. The control logic is the same as above.
3. G44.1: All axis machine tool lock signal MLK is used to set all control axes to the machine tool lock state. It is usually 0 and set to 1 when needed.
4. G108.0~G108.4: The machine tool lock signals MLK1~MLK5 of each axis are used to set the corresponding control axis to the machine tool lock state. The control logic is the same as above.
3. In manual mode, press the direction key of the faulty axis and in "PMC Maintenance" and "Signal Status", search whether the corresponding signals of G100.0~G100.4 and G102.0~G102.4 are 0. If they are 0 , then find the reason in the ladder diagram.
The above G100.0~G100.4 are the positive direction selection signals +J1~+J5 of each feed axis, and G102.0~G102.4 are the negative direction selection signals -J1~-J5 of each feed axis. These two sets of signals It is used to give signals in the positive and negative directions of the feed axis during manual feeding. The corresponding axis direction signal must be 1 during manual feeding.
4. When manually feeding, search for G10 and G11 in "Signal Status" and look at the override value in hexadecimal. If it is 0 or FF, find the reason in the ladder diagram.
The above G10 and G11 are the manual feed speed override signals *JV0~*JV15. These two sets of signals are used to give the feed axis speed signal during manual feed. In the ladder diagram, they are generally controlled by the override switch. In addition, when G10 If the values in G11 are all 1 or 0, CNC will regard the override value as 0, that is, the feed will stop.
