MDR error
- electrical or temperature errors

Blinking red
MDR detection fault (ex: Mixed MDR configuration)
* Fallback strategy applied
– see below
Fallback strategies
The following fallback strategy will be applied on a specific port where L+ is shorted (Pin 1):
- MDR LEDs go to fixed red.
- Pin1 set to 0V (Power)
- Pin2 set to 0V (Direction - counterclockwise)
- Pin5 set to 0V (Speed)
- Pin4 set to 0V (Stop - Itoh Denki only)
The following fallback strategy will be applied on a specific port where over temperature (>85°) is detected:
- MDR LED will be fixed red
- Pin1 set to 24V (Power)
- Pin2 set to 0V (Direction - counterclockwise)
- Pin5 set to 0V (Speed)
- Pin4 set to 0V (Stop - Itoh Denki only)
Therefore, the Interroll MDR will be braked and stopped immediately while the Itoh Denki MDR will continue to
turn until it stops by itself.
Communication breakdown strategy
In the event of loss of bus communication (released or lost) or when the ETHERNET/IP scanner goes to Idle
mode (Prog mode), the following strategy will be applied on all ports:
- MDR LEDs will be fixed green/orange
- Pin1 set to 24V (Power)
- Pin2 set to 0V (Direction - counterclockwise)
- Pin5 set to 0V (Speed)
- Pin4 set to 0V (Stop - Itoh Denki only)
In such case, the MDRs will be braked by applying the stop ramp (if enabled) and will be restarted by applying
the start ramp (if enabled) once the communication is back.
