Appendix 7.4 MCP Alarms (Y)
Y02 System alarm 0052 0001
Details
Transfer to buffer is not properly done in servo communication.
Remedy
Software/ hardware may have a fault.
Contact service center.
(Note 1) When two or more "Y02 System alarms 0051" alarms occur at the same time, only
the alarm which occurs first is displayed. Therefore, the display precedence will be as
follows: 0006, 0x04, 0005, 0x20, then 0x03.
(Note 2) Station No. always shows "0" in the alarm details, because C70 has only one
communication channel.
(Note 3) If the error is not cleared with the measures above, the drive unit may have a fault.
Take a note of the 7-segment LED contents of each drive unit and contact service
center.
Y03 Amp. Unequipped (Axis name)
Details
The drive unit is not correctly connected.
Alphabet (axis name): Servo axis drive unit not mounted
1 to 8: PLC axis drive unit not mounted
S: No.1 spindle drive unit not mounted
T: No.2 spindle drive unit not mounted
M: No.3 spindle drive unit not mounted
N: No.4 spindle drive unit not mounted
P: No.5 spindle drive unit not mounted
Q: No.6 spindle drive unit not mounted
R: No.7 spindle drive unit not mounted
Remedy
Check the drive unit mounting state.
- Check the end of the cable wiring.
- Check the cable for broken wires.
- Check the connector insertion.
- The drive unit input power has not been ON.
- The drive unit axis No. switch is illegal.
- Turn down the DIP switch on the drive unit of the axis corresponding to the error No. (axis
name).
- Check for any duplication of rotary switch settings on a drive unit. The LED will indicate
"11" if the drive unit has duplicate setting.
- Correct the "#1002 axisno (Number of axes)" and "#1039 spinno (Number of spindles)"
settings.
- Before setup debugging, confirm that the "#2018 no_srv (Operation with no servo control)"
is set to "1" and "#3024 sout (Spindle connection)" is set to "0" for any axis to which the
drive unit is not connected. (Note that the normal setting is "0" in "#2018 no_srv" and "1" in
"#3024 sout". )
(Note 1) This alarm is displayed for each part system. Therefore, the error No. is not
displayed unless the alarm occurs in the displayed part system.
(Note 2) When the alarm occurs on a servo axis, the error No. indicates the axis name set in
"#1013 axname (Axis name)". When the alarm occurs on a PLC axis or the spindle,
the error No. display is fixed by the order of CNC control axes.
Y05 Initial parameter error
Details
There is a problem in the value set for the number of axes or the number of part systems.
Remedy
Correct the value set for the following corresponding parameters:
“#1001 SYS_ON (System validation setup)”,
“#1002 axisno (Number of axes)”,
“#1039 spinno (Number of spindles)”,
“#2187 chgPLCax (PLC axis switchover No.)”, etc.
