C.13 Self-Diagnostics
The drive has a built-in self-diagnosing function of the serial communication interface circuits. To perform the self-
diagnosis function, use the following procedure.
DANGER! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to comply will result in death or
serious injury. Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power
supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait
at least one minute after all indicators are OFF and measure the DC bus voltage level to confirm safe level.
