Y20 Speed obsv: Para incompatible 0007 (Axis name)
Details
Two speed monitoring parameters are not matched at the rising edge of the "speed monitor mode"
signal.
The name of the axis with an error is displayed.
Remedy
Correct the relevant parameters so that the two speed monitoring parameters match.
Restart the NC.
Y20 Contactor welding detected 0008 Contactor No.
Details
Contactor welding was detected.
Displays the bit corresponding to the No. of the abnormal contactor.
Some contactors take a while to be shutdown after the servo ready is turned OFF, and the servo ready
was turned ON in the meantime.
Remedy
- Make sure that contactor's auxiliary B contact signal is output correctly to the device set on "#1330
MC_dp1(Contactor weld detection device 1)" and "#1331 MC_dp2(Contactor weld detection device
2)".
- If welding, replace the contactor.
- Restart the NC.
Y20 No spec: Safety observation 0009
Details
"#2313 SV113 SSF8/bitF (Servo function selection 8)" and "#13229 SP229 SFNC9/bitF (Spindle
function 9)" are set for a system with no safety observation option.
Remedy
Disable "#2313 SV113 SSF8/bitF (Servo function selection 8)" and "#13229 SP229 SFNC9/bitF
(Spindle function 9)".
Then, restart the NC.
Y20 SDIO connector input volt err 0010
Details
24VDC power is not supplied to SDIO connector correctly. (SDIO 4A pin supply voltage was dropped
to 16V or less, or 1ms or more instant power interrupt was detected.)
In this case, "Pw sply:Inst pw interpt(DC24V)" alarm occurs because the contactor control output
signal cannot be controlled.
This state remains until restarting the NC even if the cause of the alarm has been removed.
Remedy
Check the wiring. Supply 24VDC power to the SDIO connector.
Restart the NC.
Y20 Device setting illegal 0011
Details
- The device set in "#1353 MC_ct1 (Contactor shutoff output 1 device)" does not exist.
- The device set in "#1353 MC_ct1 (Contactor shutoff output 1 device)" is used as an output device in
PLC program.
Remedy
- In "#1353 MC_ct1 (Contactor shutoff output 1 device)", set the device to which a remote I/O is
connected. Use the device to control the contactor.
- Confirm that the devices set by "#1353 MC_ct1 (Contactor shutoff output 1 device)" are not used as
an output device in PLC program.
Y20 Contactor operation abnormal 0012 Contactor No.
Details
Contactor's operation is not following the NC's commands.
Displays the No. of the abnormal contactor.
Remedy
- Check and correct "#1353 MC_ct1 (Contactor shutoff output 1 device)" setting.
- Check the wiring for contactor shutoff.
- Check for contactor's welding.
