Details
- MCP Nos. of the servo/spindle drive units are not continuous.
- There is a duplicate setting.
- Axis No. is out of the setting range.
- Channel No. is out of the setting range.
Remedy
Check the values set for the following parameters.
- "#1021 mcp_no (Drive unit I/F channel No. (servo))"
- "#3031 smcp_no (Drive unit I/F channel No. (spindle))"
(Note 1) "#1021 mcp_no (Drive unit I/F channel No. (servo))" and "#3031 smcp_no (Drive
unit I/F channel No. (spindle))" must be continuous.
(Note 2) This alarm is displayed taking precedence over the alarms "Y02 System alarm",
"Y07 Too many axes connected" and "Y09 Too many axisno connected".
Y07 Too many axes connected 0000 - Exceeded number of axes
Details
The number of axes connected to CNC has exceeded the maximum number of connectable
axes.
The exceeded number of axes per channel is displayed as alarm No.
Remedy
- Correct the "#3024 sout (Spindle connection)" setting for the spindle to which the drive unit
is connected.
- Turn up the DIP switch for any unused axis in the multi-axes drive unit.
- Correct the "#1002 axisno (Number of axes)" and "#1039 spinno (Number of spindles)"
settings.
- Disconnect the connected axes as many as shown in the alarm No. so that the number of
connected axes will not exceed the maximum number of connectable axes.
(Note 1) This alarm occurs when the number of the connected axes exceeded the maximum
number of the connectable axes assumed in the system.
(Note 2) This alarm indicates a communication timeout state of drive unit (with "AA" in the
drive unit LED display) as the initial communication is not executed.
(Note 3) If this alarm occurs, the alarm "Y03 Message: Drive unit unequipped" will not occur.
(Note 4) This alarm is displayed taking precedence over the alarm "Y02 System alarm" and
"Y09 Too many axisno connected".
Y08 Too many drive units connected 0000 - 00FF
Details
The number of drive units connected to each channel exceeds 8.
The exceeded number of drive units per channel is displayed as alarm No.
Remedy
Remove drive units from the channel whose alarm No. is other than "0" for the number
displayed as the alarm No. Keep the number of connected drive units to 8 or less.
(Note 1) The drive unit is not counted when all the axes connected to it are invalid.
(Note 2) If this alarm occurs, the alarm "Y03 Message: Drive unit unequipped" will not occur.
(Note 3) The alarm "Y07 Too many axes connected" and "Y09 Too many axisno connected"
are displayed taking precedence over this alarm.
