E70 Series Instruction Manual
Appendix 6.4 MCP Alarms (Y)
IV - 87
Y20 No speed observation mode in door open 0006 Door No.
Details
The door open state was detected when the speed monitoring mode was invalid.
The causes may be same as the ones for 0005 (Door signal: Input mismatch). Also the sequence
program may not be correct.
Remedy
Correct the sequence program.
Restart the NC.
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.
Details
The observation speed (#2181 to #2186, #2191 to #2192, #3141 to #3144,#3149 to #3152) has
exceeded its setting range.
The name of the axis with an error is displayed.
Remedy
Decrease the observation speed or change the relevant
parameter. 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 (ssc SLS (Safely Limited Speed) function)” and “#13229 SP229 SFNC9/bitF
(ssc SLS (Safely Limited Speed) function)” are set for a system with no safety observation option.
Remedy
Disable “#2313 SV113 SSF8/bitF (ssc SLS (Safely Limited Speed) function)” and “#13229 SP229
SFNC9/bitF (ssc SLS (Safely Limited Speed) function)”.
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.
