The INIT switch bypasses the loading of any saved configuration. Use this switch if there are suspected configuration issues causing alarms on the controller that may prevent you from connecting to the MPiec controller. If the INIT switch is ON and the CNFG switch is OFF, the controller will show no axes connected.
The CNFG switch automatically configures the MPiec controller with the supported devices attached to the Mechatrolink network and I/O cards. When this switch is ON the MPiec controller can control any supported devices attached regardless if they are in a saved configuration or not. Yaskawa recommends leaving this switch on.
The SUP/MNT switch puts the MPiec controller in supervisor mode for firmware upgrades. When this switch is ON, the controller will not “control” anything (The PLC will not run.) Servos cannot be enabled and I/O cannot be read or written.
