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 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.
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 expansion
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 correspond 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.
