Details
The number of axes connected to each channel exceeds the maximum number of connectable 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 connecting
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
