C740A10 24V IO voltage is outside of the allowed range: {float}V

An error occurred in the 24V supply

Try the following actions to see which resolves the issue: (A) Check for shorts on anything attached to the IOs, (B) Conduct a complete rebooting sequence, (C) Update software, (D) Contact your local Universal Robots service provider for assistance

C740A11 48V voltage is outside of the allowed range: {float}

The 48V supply voltage is outside the allowed range. This may be due to the robot drawing too much current.

Try the following actions to see which resolves the issue: (A) Adjust the robot program to reduce peak acceleration and torques, (B) Ensure that there is no electrical short in the Control Box or robot, (C) Conduct a complete rebooting sequence (D) Update software, (E) Contact your local Universal Robots service provider for assistance

C740A15 The {float}A current draw of the robot is outside the allowed range.

The current draw of the robot is higher than what is supported by the power supply.

Try the following actions to see which resolves the issue: (A) Adjust the robot program to reduce peak acceleration and torques, (B) Ensure that the robot power cable is not shorted during operation, (C) Conduct a complete rebooting sequence (D) Update software, (E) Contact your local Universal Robots service provider for assistance

C740A20 24V IO voltage is outside of the allowed range: {float}V

An error occurred in the 24V IO supply

Try the following actions to see which resolves the issue: (A) Check the fuse in the control box, (B) Check supply to the IOs is attached, (C) Check for shorts on anything attached to the IOs, (D) Conduct a complete rebooting sequence, (E) Update software, (F) Contact your local Universal Robots service provider for assistance

C740A21 24V IO current is outside of the allowed range: {float}A

Too high current draw on 24V IO supply

Check 24V IO connections to make sure the IO current are within specified limits

C740A24 The left Three-Position Enabling button is inconsistent

Try the following actions to see which resolves the issue: (A) Do not press the button repeatedly, (B) Remove any pressure off the button, (C) Press the button with more pressure. Light pressing may not work, (D) Update software, (E) contact your local Universal Robots service provider for assistance.

C740A25 The right Three-Position Enabling button is inconsistent

Try the following actions to see which resolves the issue: (A) Do not press the button repeatedly, (B) Remove any pressure off the button, (C) Press the button with more pressure. Light pressing may not work, (D) Update software, (E) contact your local Universal Robots service provider for assistance.

C740A29 The solenoid driver curcuit encountered an error condition

The fault signal from the solenoid driver curcuit was asserted, indicating an issue with the joint electronics.

Try the following actions to see which resolves the issue: (A) Update software, (B) Replace the joint PCB.

C740A30 The brake solenoid could not be detected

The joint was unable to detect a connected brake solenoid

Try the following actions to see which resolves the issue: (A) Update software, (B) Verify that the brake solenoid cable is connected to the joint PCB, (C) Verify that the brake solenoid is not damaged.

C740A31 The robot current offset limit check has failed

The robot current offset value is outside of the allowed range

Try the following actions to resolves the issue: (A) Update software, (B) Contact your local Universal Robots service provider for assistance.

C740A32 The robot current offset integrity check has failed

The robot current offset value can't be trusted as the integrity check has failed

Try the following actions to resolves the issue: (A) Update software, (B) Contact your local Universal Robots service provider for assistance.

C740A33 48V voltage is below the minimum allowed limit: {float}

The 48V supply voltage is below the minimum allowed limit.

Try the following actions to see which resolve the issue: (A) Make sure that the combination of robot arm and control box is supported, (B) Adjust the robot program to reduce peak acceleration and torques, (C) Ensure that there is no electrical short in the Control Box or robot, (D) Conduct a complete rebooting sequence (E) Update software, (F) Contact your local Universal Robots service provider for assistance

C740A34 48V voltage is above the maximum allowed limit: {float}

The 48V supply voltage is above the maximum allowed limit.

Try the following actions to see which resolve the issue: (A) Make sure that the combination of robot arm and control box is supported, (B) Adjust the robot program to reduce peak decelerations and torques, (C) Ensure that there is no electrical short or loose connections in the Control Box or robot, (D) Conduct a complete rebooting sequence (E) Update software, (F) Contact your local Universal Robots service provider for assistance
