8.4 Noise Prevention
In case a trouble is occurred and is suspected to be noise-related, have the actions described
below to strengthen the noise countermeasure. It is not that you need to have all the items to be
conducted to prevent noise.
(1) Mount a noise filter
(Note 1)
on motor power input line and attach a surge absorber
(Note 1)
on the
primary side of the noise filter.
(2) Attach a clamp filter
(Note 1)
on line of the secondary side of the noise filter.
(3) Attach a clamp filter on each of MSCON side and actuator side of the motor cable.
Note 1: Select yourself the best ones for your own system.

FPGA error
(Faulty component)
The FPGA is not operating properly.
Cause
: 1) Malfunction due to the effect of noise, etc.
2) Faulty FPGA
3) Faulty circuit component around the FPGA.
4) Inappropriate board installation in the controller.
Treatment : Turn the power OFF and reboot.
If the error occurs again, check for presence of
noise.
If a spare controller is available, replace the
problem controller with the spare controller.
A recurring error with the spare controller suggests
presence of noise.
If the cause cannot be identified, please contact IAI.
