 Output terminal function (open collector, relay outputs) setting and detection levels
For the open connector output terminals (OUT1, OUT2) and the relay output terminals (FLA, FLB and FLC),
functions can be selected from 0 to 255 functions. The selectable functions and detection levels are listed in the
table below.
Up to 7 output terminals can be used if add-on options are used in combination with the inverter, while up to 3
output terminals can be used if no add-on option is used.
<Technical terms>
• Alarm
• Pre-alarm
• Serious failure ·······Output signal in a serious failure of the protection function of the inverter.
• Light failure
• Emergency stop ·······Output signal when the inverter comes into emergency stop.
