4-2 Function Mode Alarm Code Output (AC0 to AC3) •This function outputs a 3-bit or 4-bit code signal to indicate the cause of an Inverter trip. •If "01" (3-bit) or "02" (4-bit) is selected in alarm code selection C062, multi-function output terminals P1 to P3, or P1 to P4, are forced to output an alarm code. The following table shows the output alarm codes. 4 Functions 4-97 Parameter No. Function name Data Default setting Unit C062 Alarm code selection 00: Disabled 00 01: 3-bit code 02:
