[Servo board XX] Internal valve/sensor interface board not installed. (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Possible.

Content: The internal valve/sensor interface board (1UU board) for RS03 is unavailable. This board can only be used with the RS03 robot.

Main causes:

1. [User sensor inputs] or [Built-in valve outputs] in auxiliary function [610 Robot arm internal I/O signal settings] is set to "Enabled", but the internal valve/sensor interface board (1UU board) is not installed.

2. The 1UU board is faulty.

3. The 1UU board type is different. (A board without JP1 and JP2 installed cannot be used.)

Countermeasures:

1. Check whether the internal valve/sensor interface board (1UU board) is installed. For a robot other than RS03, [User Sensor Input] and [Built-in Valve Output] in auxiliary function [610 I/O Signal Settings Inside Robot Arm] are set to "Disabled".

2. If this error still occurs although the board is installed, replace the internal valve/interface board (1UU board).

3. Replace the 1UU board with the correct model.
