Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.
CB warning 1 indicates a problem with the communication board. The manual's first action is: “See CB user manual”
RTOS Overrun Warning indicates a software error in the real-time operating system. The manual lists no action for this code.
Motor data identification is active and running. The manual's first action is: “Wait until motor identification is finished”
Motor Over-temperature ï† indicates the motor has exceeded its temperature limit. The manual's first action is: “Check the following: 1. P0611 (motor ï† time constant) should be set to appropriate value 2. P0614 (Moto…
The inverter duty cycle has exceeded allowable temperature limits. The manual's first action is: “Check if duty cycle are within specified limits”
Inverter ï† indicates warning level exceeded with current reduced if parameterized. The manual's first action is: “Check if duty cycle is within specified limits”
Inverter Over-temperature code A0504 indicates the heat-sink temperature has exceeded warning level, causing reduced output. The manual's first action is: “Check if ambient temperature is within specified limits”
The inverter has detected a voltage level below the minimum acceptable limit. The manual's first action is: “Check main supply voltage (P0210)”
The inverter has detected an overvoltage condition that exceeds the allowable limit. The manual's first action is: “Check that mains supply voltage is within allowable range”
The inverter has detected a current limit condition. The manual's first action is: “Check whether the motor power corresponds to the inverter power”
BIST Tests Failure (Service mode only) indicates internal tests have failed. The manual's first action is: “1. Inverter may run but certain actions will not function correctly 2. Replace inverter”
PI Feedback above maximum value P2267 The manual's first action is: “1. Change value of P2267 2. Adjust feedback gain”
PI Feedback below minimum value P2268 The manual's first action is: “1. Change value of P2268 2. Adjust feedback gain”
F0101 indicates a software error or processor failure. The manual's first action is: “1. Run self test routines 2. Change inverter”
External Fault is triggered via terminal inputs The manual's first action is: “Disable terminal input for fault trigger”
