17.14 AMP Monitoring Function

17.14.1

Overview

This function enables the FP-XH M8N Control Unit to monitor the status information of servo
amplifier using RTEX monitor commands.
• This information can be read by controlling the AMP monitor & control area (common area
no. 0, address H390-H395) in the positioning memory of the FP-XH M8N Control Unit using
user programs.
• The AMP monitor function can be executed only when the axes to be monitored stop. The
monitoring request made while the axes are activated is invalid. However, if the request for
monitoring is enabled when the axes stop, the monitoring starts.
• When the network disconnection error occurs, this function cannto be executed becuase
communication is not available.
