KEY POINTS
•
In the system using FP7 MC Unit, limit switches are connected to the
general-purpose inputs (SI-MON3 and SI-MON4) of Servo Amplifier A5B.
When the "Limit switch" is set to "Enabled" in the above parameter, the
state of the general-purpose inputs (SI-MON3 and SI-MON4) of Servo
Amplifier A5B is reflected as the limit inputs of FP7 MC Unit.
•
It is recommended to select "Normal Open (A contact)" for "Limit + Switch
logic" and "Limit - Switch logic". The input logic selected on the servo
amplifier A5B is reflected as is.
