error
When the simple absolute unit encoder command is issued, the
response could not be properly received.
Cause:
[1] The controller is powered up before the simple absolute unit
when the 24-V power supply is turned on.
[2] The simple absolute unit cannot communicate properly due to
noise, etc. The controller cannot communicate properly with the
simple absolute unit because the communication line in the
encoder cable is disconnected.
Action:
[1] Make sure that the simple absolute unit is powered up before (or
simultaneously with) the controller.
[2] Change the installation location of the controller. Implement noise
measures such as installing a FG, noise filter, clamp filter, etc.
Check the connectors on the encoder relay cable between the
controller and the simple absolute unit for looseness. Or, replace
the cable.
