It varies according to the setting of PANATERM.KEY POINTS• When using FP7 MC Unit in combination with Servo Amplifier A5B, thegeneral-purpose inputs (SI-MON3 and SI-MON4) are used as limit inputs. Forusing the general-purpose monitor inputs (SI-MON3 and SI-MON4) as limitinputs, 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 inuptson the MC Unit side. Do not allocate the over-travel inhibit inputs (POT,NOT) to the I/O connector (X4) of Servo Amplfiier A5B.REFERENCE• For details of the parameter settings, refer to "4.5 Connection of Limit andNear Home Switches".
