Name Details
Brake unit cooling fin overheating
The inverter output will stop if the brake unit's cooling fin temperature rises above the
specified value.
Control board ambient temperature error
The inverter output will stop if the ambient temperature of the control board rises above
the specified value.
Output overcurrent
The inverter output will stop if the inverter's output current flows above the specified
value.
Cooling fan power supply error The inverter output will stop if the cooling fan's power drops below the specified value.
Capacitor overcurrent
The inverter will stop if a current exceeding the specified value flows to the main circuit
smoothing capacitor.
Cooling fin overheat
The inverter output will stop if the cooling fin's temperature rises above the specified
value.
Gate power supply error
The inverter output will stop if the gate power supply voltage drops below the specified
value.
