(Note 1): The above table shows the allocation before shipment. It varies according to the setting of PANATERM.
• When using FP7 MC Unit in combination with Servo Amplifier A6B/A5B, the
general-purpose inputs (SI-MON3 and SI-MON4) are used as limit inputs. For
using the general-purpose monitor inputs (SI-MON3 and SI-MON4) as limit
inputs, the setting of the limit switch should be set to "A: Enabled" in the
"Axis parameter setting" menu of CMI.
• The over-travel inhibit inputs (POT, NOT) cannot be used as the limit inputs
on the FP7 MC Unit side. Do not allocate the over-travel inhibit inputs (POT,
NOT) to the I/O connector (X4) of Servo Amplifier A6B/A5B.
