Power ON Time Over (236: ONT)
• Allocate “236: ONT” to Output Terminal [DO1] Function Selection (3005Hex-15Hex) and Output Ter-
minal [ROA, ROB] Function Selection (3005Hex-1CHex).
• The power ON time of the inverter's main circuit is counted and output to Cumulative Operation
T
ime (3003Hex-15Hex). When RUN Time Over (RNT)/Power ON Time Over (ONT) Detection Level
(301FHex-37Hex) elapses, the ONT terminal (236: Power ON time over) turns ON.
RUN time over (238: RNT)
• Allocate “238: RNT” to Output Terminal [DO1] Function Selection (3005Hex-15Hex) and Output Ter-
minal [ROA, ROB] Function Selection (3005Hex-1CHex).
• T
ime is measured during inverter operation (inverter output signal (35: RUN2) is ON) and the result
is output to Total RUN Time Monitor (3017Hex-50Hex). When RUN Time Over (RNT)/Power ON
Time Over (ONT) Detection Level (301FHex-37Hex) elapses, RNT terminal (237: 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.

Maintenance Timer (3005Hex-15Hex, 3005Hex-1CHex = 84: MNT)
Allocate “84: MNT (Maintenance timer counted up)” to Output Terminal [DO1] Function Selection
(3005Hex-15Hex) and Output Terminal [ROA, ROB] Function Selection (3005Hex-1CHex).
The signal is output when 1st Startup Count for Motor (3008Hex-2DHex) reaches the value set at 1st
Preset Startup Count for Motor Maintenance (3008Hex-50Hex), or 1st Cumulative Motor Run Time
(3008Hex-5FHex) reaches the value set at 1st Motor Maintenance Interval (3008Hex-4FHex).
