MCP Alarms (Y)
I - 33
Y07 Too many axes connected 00xy
Details
The number of axes connected to each channel exceeds the maximum number of connect-
able axes.
The exceeded number of axes per channel is displayed as alarm No.
x: Exceeded number of axes at drive unit interface channel 2 (0 to F)
y: Exceeded number of axes at drive unit interface channel 1 (0 to F)
This alarm also occurs when the drive unit is connected only with the 2nd channel without con-
necting with the 1st channel.
Remedy
Remove connected axes from the channel whose alarm No. is other than '0' for the number
displayed as the alarm No. Keep the number of connected axes to or less than the maximum
that can be connected.
(Note 1) The number of axes is limited per each drive unit interface channel.
(Note 2) Maximum number of axes that can be connected differs depending on whether or not
an expansion unit is available or the setting of '#11012 16 axes for 1ch (Connecting 16
axes for 1ch)'.
With the expansion unit, up to eight axes can be connected to a channel. Without the ex-
pansion unit, up to eight axes are allowed when '#11012 16 axes for 1ch (Connecting 16
axes for 1ch)' is set to '0', sixteen axes when set to '1'.
(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 'Y08 Too many drive units
connected' and 'Y09 Too many axisno connected'.
Y08 Too many drive units connected 00xy
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.
x: Exceeded number of drive units at drive unit interface channel 2 (0 to F)
y: Exceeded number of drive units at drive unit interface channel 1 (0 to F)
Remedy
Remove drive units from the channel whose alarm No. is other than "0" for the number dis-
played 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.
Y09 Too many axisno connected 00xy
Details
The No. of the axis (drive unit's rotary switch No.) connected to each channel is bigger than
the No. allowed.
If the axis No. of each channel is bigger than the No. allowed, "1" is displayed for the alarm No.
x: "1" when the axis No. at drive unit interface channel 2 is too big
y: "1" when the axis No. at drive unit interface channel 1 is too big
Remedy
For the channel whose alarm No. is "1", keep the axis No. (drive unit's rotary switch No.) not
bigger than the No. allowed.
(Note 1) The axis No. is limited per each drive unit interface channel.
(Note 2) The biggest allowed connected axis No. differs depending on whether or not an ex-
pansion unit is available or the setting of "#11012 16 axes for 1ch (Connecting 16 axes
for 1ch)". The biggest connectable axis No. is as shown below.
With the expansion unit, axes No. '0' to '7' can be connected.
Without the expansion unit, axes No. '0' to '7' are allowed when '#11012 16 axes for 1ch
(Connecting 16 axes for 1ch)' is set to '0', axes No. '0' to 'F' when set to '1'.
(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 "Y08 Too many drive units
connected".
(Note 5) The alarm "Y07 Too many axes connected" is displayed taking precedence over this
alarm.
Y11 Node Detect Err 8002-8300 xy00
Details
Drive unit does not respond to the request from NC when the NC is turned ON.
Error No. shows the No. of communication phase at which the response stopped.
x: Channel No. (0 or later)
y: Station No. with the error (0 or later)
Remedy
The communication error may be caused by the drive unit software version that does not cor-
respond to the NC software version. Check the drive unit software version.
This alarm is canceled after the NC restarts.
When the alarm is not canceled, write down the alarm No. and contact service center.
Y12 No commu. with axis drv unit
Details
Although the high-speed synchronous tapping option is valid, the connected drive unit doesn't
support the option.
Remedy
Replace the drive unit with that supports the option.
Y13 No commu. with sp drv unit
Details
Although the high-speed synchronous tapping option is valid, the connected drive unit doesn't
support the option.
Remedy
Replace the drive unit with that supports the option.
Y14 Comm btwn drives not ready
Details
Communication between drive units failed to be ready within a specified time.
Remedy
- There may be a faulty connection of drive units.
- Check if any of drive units is broken.
