Table 4-4.1: Specific error codes for error xH4
Inverter module protection
DC bus low voltage protection
DC bus high voltage protection
Compressor frequency variation greater than 15Hz within one second protection
Actual compressor frequency differs from target frequency by more than 15Hz protection
Notes:
1. 'x' is a placeholder for the compressor system (compressor and related electrical components), with 1 representing compressor system A and
