MKD-C

The LED 7-segment display indicates the status of the drive after the 24 V supply is switched on.

MKD fault codes or warning codes are displayed constantly if present. Fault messages are coded with "F" or "E", warnings are coded with "n".

The IP address can be flashed across the 7-segment display by pressing B1 Push-button (B1).

The IP address can be configured with rotary switch S1 Rotary Switch (S1), Setting IP address.

EtherCAT STAT LEDs: There is one LED per string. As the LED is a bi-colored LED, it is used to display both the RUN (Green) and Error (RED) status.

EtherCAT L/A LEDs: These are the EtherCAT Link/Activity LEDs associated with the Motion Bus IN (X10) and OUT (X11) ports. Activity description seetable above.

MKD-N

DRIVE LEDs: There is one LED per Axis. The LED delivers information with three colors (red, green, orange) and blink frequency (see WorkBench Help).

Color Remarks
Green Enabled and running
blink green/orange Enabled and running with warning
blink orange Safe bus voltage
blink red/orange/green Fault

Local Fieldbus STAT LEDs: There is one LED per Axis. As the LED is a bi-colored LED, it is used to display both the RUN (Green) and Error (RED) status.

Local Fieldbus L/A LEDs: These are the Link/Activity LEDs associated with the Local Fieldbus Bus IN (X27) and OUT (X28) ports. Activity description see EtherCAT RUN Status (green).
