Once the inspection and the parameters of the hardware connection of the Mitsubishi CNC, the green system ready on the screen is still not shiny. And in[Diagnostic]-[Alarm]Witches a lot of alarm content on the screen, which confuses debugging engineers using Mitsubishi CNC for the first time. And there are more than 700 Mitsubishi CNC parameters. How to relieve the defect alarm? This article explains the above problems based on the debugging experience, in order to help the debugging engineer.
1. Put the parameters
1.1 Basic parameters parameters
Once the original system is activated, the Japanese is displayed. (Some systems, such as C64, do not have simplified Chinese specifications, set # 1043 = 15 traditional Chinese).
Set # 1138 = 1 (select the parameter with the number of parameters), that is to say, after entering the parameter number, the screen immediately passed to the parameter screen.
Here are the parameters that must be defined after starting:
# 1001 -Setting if it is a unique system or a double system and the PLC tree.
# 1002 -Set the number of axes of the NC axis and the PLC axis.
# 1013 -Sese the name of each axis.
# 1037 -g -code System and type of compensation
(Engine: # 1037 = 2, Tour # 1037 = 3)
(This parameter must be defined before formatting # 1060)
# 1060 – This parameter is particularly important. Its function is “the initialization of the start of the execution system”
The function is 2: one is to initialize the parameters as a function of the adjustment values of # 1001 — # 1043. The importance is that the number of NC axes and the main axis have been defined in # 1001 – – # 1043. Otherwise, the parameters of each servo tree and the spindle will not be transferred.
The second is to format processing procedures and tool compensation data. Enter the standard fixed cycle.
After precisely defining the # 1001 parameter — # 1043, define the # 1060 according to the prompt. # 1155 = 100 # 1156 = 100
The fixed signal address specified by the Mitsubishi NC system is as follows:
1 point of original point x18 1 axis + limit x28 1 axis -Limit x20
2 axes Original point x19 2 axis + limit x29 2 axis -Limit x21
Original point at 3 axes x1A 3 axis + limit x2a 3 axis -Limit x22
4 -axis Original point x1b 4 axis + limit x2b 4 axis -Limit x23
If the address of the entry signal occupied by the original points switch and the limit switch is different from the system specified by the system, it must be modified by defining the parameters
# 2073 -Set the address of the original point signal
# 2074 -Set the address of the positive limit signal
# 2075 -Set a negative limit signal address
# 1226’s bit5 = 1 (the above parameters are valid)
1.2 Servomotor parameters parameters:
# 2219 – (resolution of the location encoder)
# 2220 = – (resolution of the speed encoder)
# 2225 = — (model model)
# 2236 – (the connected Renaissance braking resistance model or a supply unit unit model) 1.3 parameters related to the main axis
The following parameters must be defined when the system is equipped with a pin:
# 1039 – (Define the system for several main axes);
# 3024 – (Define the connected main axis type
# 3024 = 1. Bus connection is the main axis of the servo)
# 3024 = 2 The simulation output is the main axis of frequency conversion)
# 3237 = 0004 (PLG is valid)
# 3238 = 0004 # 3025 = 2 (feedback from the coder is valid. Display the actual speed of the main axis)
# 3239 – Type of servo -Broche reader
# 3240 – The type of spindle engine
# 3241 – The connected braking unit or the type of braking resistance
1.4 PLC parameter
# 6449 = 00000011 -The counter in the PLC program, the timer takes effect.
# 6450 = 00000101 – Information on alarms and operating information takes effect.
# 6451 = 00110000 -plc Program communication is valid.
There are up to 700 Mitsubishi NC settings.
2. Common defect alarm and exclusion after starting
It may be after starting[诊断]-[报警] There are many default alarms on the screen, and a certain alarm debugging is not the same as the real phenomenon, and the analysis and judgment must be lifted.
2.1 [M01 0006 XYZ]—— This alarm indicates that a certain or 3 axis exceeds the hard limit.
Phenomenon: The real situation is that each axis has not been moved to the limit switch.
Analysis and exclusion of defects:
A. The signal address of each limit switch is connected in accordance with system regulations, but it is connected to a normal opening point, so the system detects the calendar failure.
Elimination: You just need to connect the limit switch to a normal closed point and the defect is eliminated.
B. The signal address of each limit switch is not connected in accordance with system regulations.
Elimination: Define parameters # 2073, # 2074, # 2075, # 1226, and the limit switching signal is connected at a normal closure point.
2.2
[S02 2219 XYZ] ,,
[S02 2220 XYZ] ,,
[S02 2225 XYZ],,
[S02 2236 XYZ]—— The error of the initial parameter parameters.
Elimination: This means that the servo parameters defined after starting are wrong and that the parameters must be defined according to the motor or encoder model.
2.3 [Y03 MCP XYZ]—— The servo player is not installed
Phenomenon: The real situation is that the servo player has been installed. Why does this type of alarm occur?
Analysis and elimination:
1. Each connection cable is not closely inserted and the cables are disconnected and tight.
2. There is a cable failure and the cable is replaced.
3. The order of the call is false. You must first serve the system and finally call the controller.
4. The pilot’s axis number is adjusted correctly.
2.4 [Z55－RI/O未连接]
Phenomenon: The real situation is that the system is not equipped with RI / O. But why this alarm?
Analysis: ● the power order – is false. First call the controller, then call the Rio.
●. The main cable CF10 (controller and s) is poorly connected.
Elimination:
1. Edit the order of electricity.
2. Reinitated the CF10 and tight cable.
3. Check the RI / O power.
2.5 [EMG LINE]—— The emergency stop due to an inappropriate connection
Analysis: It can be the failure of a cable or a connection failure.
Elimination: re-insure the cables and tighten them. Or replace the SH21 cable to R000
cable. Generally, there are 10 cables in the SH21 cable, but the C1 type player must use the R000 cable. The R000 cable must be full of 20 cables.
2.6 [EMG SRV]- – This because of the emergency stopping of the failure of the servomotor system
analyze:
1. Disconnecting the SH21 cable can cause failure. A bad connection of the SH21 cable can also fail.
2. The energy production failure sequence will also occur.
Elimination: Replace the SH21 cable and call it in normal order.
2.7 [ EMG PLC]—— is an emergency stop caused by the PLC program
Elimination: Y29F surveillance = on the cause caused by the PLC program to relieve the failure caused by emergency stops.
2.8 [EMG STOP]—— The PLC program is not running.
Elimination:
Check if the “NCSYS” button behind the controller is = 1 “
Set the button to “0”
Define PLC = “run” on the screen.
After carrying out “Formatting PLC Memory” on the communication screen of GX-D software, the PLC program is reopened.
2.9[U01——-无用户PLC]—— The PLC program has not entered
Elimination: Enter the API program.
