[Al. 090_Homing Incomplete Warning] - Mitsubishi Electric MR-J5-G Series User Manual

[AL. 090_Homing incomplete warning]

• Homing has not been finished.
• Homing did not complete properly.
• Homing was executed with the Z-phase unpassed.
[AL. 090.1_Homing incomplete]
Cause
1.
Homing has not been executed.
2.
Positioning operation was executed without
homing after [AL. 025 Absolute position
erased] occurred in the absolute position
detection system.
3.
Homing completion 2 (S_ZP2) turned off after
homing was executed.
4.
[AL. 069 Command error] occurred.
[AL. 090.2_Homing termination error]
Cause
1.
The proximity dog was not connected to DOG.
2.
The stroke limit was detected after homing
was started.
3.
Deceleration from the homing speed to the
creep speed was not possible.
[AL. 090.5_Z-phase unpassed]
Cause
1.
Homing was executed while the servo motor
did not pass the Z-phase.
2.
The Z-phase signal was not detected normally.
Check/action method
Check if homing was executed.
If homing was not executed, execute homing.
Execute homing after dealing with [AL. 025].
Refer to "Homing mode (hm) and homing" in the following manual.
MR-J5 User's Manual (Function)
Remove the causes that turned off homing completion 2 (S_ZP2), then
execute homing again.
Refer to "Homing method list" in the following manual.
MR-J5 User's Manual (Function)
Execute homing after dealing with [AL. 069].
Refer to "Homing mode (hm) and homing" in the following manual.
MR-J5 User's Manual (Function)
Check/action method
Check if the proximity dog is connected correctly.
Check the status of the input signal on the I/O monitor screen of MR
Configurator2.
Check if the stroke limit switch is connected correctly to the servo amplifier, or
check if the stroke limit has been reached.
There is a possibility that the proximity dog turned off before deceleration from
the homing speed to the creep speed was completed.
Review the dog position or review the parameter values of the homing speed,
the creep speed, and the travel distance after proximity dog.
Check/action method
Review the homing start position and the proximity dog position so that the
servo motor passes the Z-phase signal until the proximity dog turns off after
homing started.
Check if the Z-phase signal of the servo motor or the linear servo motor was
detected normally.
If a linear encoder is being used, replace the linear encoder.
Replace the rotary servo motor or the direct drive motor.
