Alarm Code Output Function (Ac0 To Ac3) (C021 To C025, C062) - Hitachi L700 SERIES Instruction Manual

Chapter 4 Explanation of Functions
4.2.65 Alarm code output function (AC0 to AC3)
The alarm code output function allows you to make the inverter
output a 3- or 4-bit code signal as the trip factor when it has
tripped.
Specifying "01" (3 bits) or "02" (4 bits) for the alarm code output (C062) forcibly assigns the alarm code
output function to intelligent output terminals [11] to [13] or [11] to [14], respectively.
The following table lists the alarm codes that can be output:
