■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	·······Alarm output beyond a certain setting value.
• Pre-alarm	·······Alarm output of the state where the inverter may carry out a trip by continuation.
• Serious failure	·······Output signal in a serious failure of the protection function of the inverter.
	(Arm overcurrent (￿￿￿￿, ￿, ￿), Load side overcurrent (￿￿￿), Short-circuiting
	(￿￿￿, ￿￿￿), Phase failure (￿￿￿￿, ￿￿￿￿), Abnormal output current detection
	(￿￿￿￿))
• Light failure	·······Output signal in a slight failure of the protection function of the inverter.
	(Overload (￿￿￿,￿), overvoltage (￿￿￿, ￿, ￿), overcurrent during
	acceleration/deceleration/fixed speed operation (￿￿￿, ￿￿, ￿, ￿￿, ￿, ￿￿))

•Emergency stop ·······Output signal when the inverter comes into emergency stop. Stopping manner is set with ￿￿￿￿ (emergency stop).
