Power ON Time Over (236: ONT)
To output this signal, allocate “236: ONT” to Output Terminal [DO1] Function Selection (E20), Output
Terminal [DO2] Function Selection (E21) or Output Terminal [ROA, ROB] Function Selection (E27).
The power ON time of the inverter's main circuit is counted and output to Cumulative Operation
Time (M20). When RUN Time Over (RNT)/Power ON Time Over (ONT) Detection Level (E154)
elapses, the ONT terminal (236: Power ON time over) turns ON.
RUN time over (238: RNT)
To output this signal, allocate “238: RNT” to Output Terminal [DO1] Function Selection (E20), Output
Terminal [DO2] Function Selection (E21) or Output Terminal [ROA, ROB] Function Selection (E27).
Time is measured during inverter operation (inverter output signal (35: RUN2) is ON) and the result
is output to Total RUN Time Monitor (W179). When RUN Time Over (RNT)/Power ON Time Over
(ONT) Detection Level (E154) elapses, RNT terminal (238: RUN time over) turns ON.

Maintenance monitor
The Maintenance timer counted up (MNT) signal is output when the cumulative operation time for mo-
tor 1 exceeds the preset time, or when the number of startups for motor 1 exceeds the preset number
of times.
