After investigation, this hardware error is "Input Voltage Error".
Now, only one H54 is connected to 24v/0.07A power source, after starting this servo, there is a 9.79v/1.08A, At this moment, the vibration to the servo is much obvious. How do I make this exception gone?

Hi,


It looks like your power source is either too small, or there could be something wrong in DYNAMIXEL.

While under standby mode, H54-200-S500-A will consume about 80mA, and if your current meter is reading 1.08A, your DYNAMIXEL may have been damaged.

Please ask RMA service for more details.

Thank you.
