Hitachi OC. Accel fault code meaning

Hitachi / OC. Accel

Series: HFC-VWS

Overcurrent during motor acceleration

AC drive

Meaning: Connected inertia is too large to be accelerated within the time set; output short-circuit or ground fault; start or jogging frequency set too high; torque boost set too high; motor constrained. (Table 8-2: when the output side is shortcircuited or the motor is constrained a large current flows; output is cut off; type of operation is identified.) | Prolong the acceleration time; correct the short-circuit or ground fault; reduce the start or jogging frequency adjustment; reduce the torque boost adjustment; release the motor from the constrained state. If the inverter module is damaged replace
