We have machining center with GSK983M-H-3R system and DA98D-08 servo driver, 401 alarm shows when starting the system, we checked that there is no enable signals for input on AC servo driver by monitoring mode, and no servo ready signal for output, but if the CNC is not turned on, then there is input signal, the servo ready signal is still nothing, what is the problem?

Could be somewhere cable broken, please kindly check.
