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 pe r each drive unit interface channel.

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'.
