Frequently Asked Questions
Overcurrent Alarm (displays "oCF") and Tripping Immediately After Startup
This is a high-frequency issue when the inverter is used with kneaders and small conveyors in food processing plants. Inspection may reveal motor cable insulation damage or sudden heavy material loading causing current surge. To troubleshoot: check for cable damage, manually rotate the motor shaft to check for jams, and appropriately extend the acceleration time parameter.
Displays "PRA" Lock and Inverter Is Completely Unresponsive
This often occurs with Altivar 12 inverters paired with access control devices and small labeling machines. Usually caused by ignoring the requirement to short the +24V terminal and PWR terminal during on-site wiring. Use a multimeter to measure if there is a stable 24V voltage between +24V and 0V. If normal, short the two terminals to unlock.
Frequent Shutdown Due to Poor Heat Dissipation and Abnormally Hot Housing
This is particularly common in dusty environments. The inverter's cooling fan is prone to clogging with dust. Normally, the inverter's operating temperature inside the distribution cabinet should be 30 - 50℃. To resolve: regularly clean the heat sink with compressed air (at least once a year) and avoid blocking the inverter's heat dissipation channels.
Displays "CFF" Configuration Error and Fails to Operate Normally
This often happens after equipment maintenance, accessory replacement, or reprogramming. Usually due to a mismatch between replaced accessories and the inverter's power specifications. To fix: enter the "fcs" option in the "conf" menu to reset parameters to factory defaults, then reconfigure programming parameters according to the motor nameplate.
Displays "OPF1" Phase Loss Fault and Abnormal Motor Operation
This mostly occurs with three-phase motor-compatible Altivar 12 models. Triggered when the inverter detects excessively low current or an open circuit in one phase of the motor circuit. To troubleshoot: retighten the wiring terminals, use a clamp meter to check if the current in each phase is balanced, and inspect for motor line damage.
