9.1 LED status displays
The LED status displays on the front of the i700 servo inverter provide quick information on some
operating states.
• The two LEDs "RDY" and "ERR" serve to indicate the device status.
• Three green LEDs at the EtherCAT interfaces (RJ45 sockets X4 and X5) serve to indicate the
EtherCAT bus status and the connection status of the input and output socket. The arrangement
of the LEDs can be seen from the "Servo-Inverter i700" hardware manual.
