[Cause]
6 The DC voltage of the main circuit power supply of the axis servo amplifier (DC link voltage) dropped abnormally. The numbers in parentheses indicate the action group number and the axis number within the action group. The alarm is displayed on the 1th and 2th axes of the 6 axis amplifier, or on the 1th, 2th and 3th axes.
[Countermeasures]
1. The power supply may be momentarily interrupted. Check the power supply voltage.
2. Confirm that the input voltage of the control device is within the rated value and confirm that the transformer is set correctly.
3. On systems with additional axes, it may be caused by the simultaneous acceleration of the robot and the additional axes. Check the program.
4. In a system with additional axes, this alarm may be issued if a reset signal is input simultaneously with SVOFF and an emergency stop signal such as guardrail opening. After inputting the emergency stop signal, please be careful not to input the reset signal within 2 seconds.
5. Replace the emergency stop unit.
6. Replace 6 shaft amplifier.
7. Replace the common power supply (iPS).
Note To clear this alarm, power needs to be cycled.SERVO DCHVAL(PS) Alarm (G:%d A:%d)
