High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• Use this function to allocate the functions listed below to the multi-function output P1 to P5 terminals
and the multi-function relay output (MA, MB) terminals.
• The multi-function output P1 to P5 terminals are for open collector output and the multi-function relay
output (MA, MB) terminals are for relay output.
• Set the desired function in the Multi-function Output P1 to P5 Selection (C021 to C025) and the
Multi-function Relay Output (MA, MB) Function Selection (C026).
• These output terminals can be set to either NO (Normally open contact) or NC (Normally closed
contact) in the Multi-function Output P1 to P5 Operation Selection (C031 to C035) and the
Multi-function Relay Output (MA, MB) Operation Selection (C036) independently.
• If the alarm code output function is enabled in Alarm Code Selection (C062) (Alarm Code Output
(AC0 to AC3) on page 7-130), some multi-function output settings are disabled.
When C062 is set to 01 (3 bits), the output terminals P1 to P3 are used for alarm code output; when
C062 is set to 02 (4 bits), the output terminals P1 to P4 are used for alarm code output.
