Error no. H8810
Error occurred by the data transmission to the servo
Check the communication cable connection. Check that there is not a source of noise.
ID of the com. data with the servo is not corresponding
Turn the power OFF and ON once
The communication with the servo became a timeout
Turn the power OFF and ON once
The servo amplifier cannot be detected
Check the cable connection and the power supply of amp.
The axis setting is not correct
Check the servo axis settings (parameters, rotary switches)
Uncorrespondence amplifier is connected
Remove the uncorrespondence amplifier
The communication protocol which does not correspond
Remove the uncorrespondence amplifier
