Cube Servo Error/Damage

When a particular Cube Servo LED is blinking

The blinking LED on the Cube Servo indicates that the motor is overloaded or there is an internal sensor damage. Please allow the Cube Servo to cool down before you continue using it, else contact rero support team at support@rero.io for further assistance.

1. Turn OFF the rero Controller for 5 minutes.

2. Then switch the rero Controller back ON, go to Servo page and check if the particular motor is detected.

3. If the Cube Servo is detected and working properly, please revise your robot design to reduce load or set path limit again.  

 

Cube Servo is not detected by the rero Controller

1. Unplug all the Cube Servo cables from the rero Controller.

2. Connect one of the Cube Servos to the rero Controller,

3. Turn ON the rero Controller and check whether the red LED of the Cube Servo light up for 0.5 second.

4. On the main menu, enter the Servo page and check if that Cube Servo is detected.

- If YES, repeat steps 2 to 4 for all the Cube Servos.

- If NO, please proceed to the following steps.

5. Change to another rero Controller port to verify if the problem still persists.

6. Check whether the Cube Servo wire is damaged.

7. If all of the above verifications fail, please contact rero support team at support@rero.io

 

Cube Servo Output Connect Damage

1. Using the Allen-key provided, remove the screw at the output connect.

2. Replace the new output connect to the Cube Servo. Make sure to align the yellow triangle to the mark at the Cube Servo.

3. Secure the screw by tightening it.

Wire Connection

Two Methods of Wiring

- Direct Wiring: Each Cube Servo (Male Connector) is connected directly to the rero Controller.

 

 

- Daisy Chain Wiring: Cube Servos are connected to each other (Daisy Chain) and one of the Cube Servos (Male Connector) is connected to the rero Controller.

Note: The rero Controller has a total of 6 ports. Each port may support up to a maximum of 10 Cube Servos or Sensors. Overall, it may support up to a maximum of 60 Cube Servos or Sensors. 

 

Connection Between 2 Cube Servos

First Cube Servo (Male Connector); connects to the 2nd Cube Servo (Male connector).

 

Connection Between Cube Servo and the rero Controller

First Cube Servo (Male Connector) is connected to the rero Controller port.

Hardware Rules

The Connects and Joints

 

Rule #1: Always use Adapter Joints on the rero Controller.

Rule #2: Follow the yellow arrow at the Cube Servo’s output connect.

Product and Manufacturing

rero Controller Errors

Unable to Shut Down

If the error screen below is seen during shutting down, this indicates that the controller PCB is spoiled and the power to the servo motor/sensor cannot be turned off.

Please remove the battery from the controller to prevent over-discharging.

 

 

Low Battery Level

When the battery level falls below 10%, the system will show the screen below and shut down automatically after 5 seconds.

This is to protect the battery. Please recharge or change to another batterypack before you continue to operate the system.

 

Forced Shutdown

If the rero Controller hangs or fails to respond, you can force shutdown by pressing and holding the "Power" button for >5 seconds.

If the rero Controller still refuses to shut down, you can manually shut down by removing the battery. Please check "How to charge the rero battery? (Charging directly via LiPo battery charger)" on ways to remove the battery.
