Running Time Over And Power-On Time Over Signals (Rnt And Ont) - Hitachi NES1-004SB Quick Reference Manual

Chapter 7 Explanation of Functions
7.8.10 Running time over and power-on time over signals (RNT and ONT) [b034]
The inverter outputs the operation time over (RNT) signal or the plug-in time over (ONT) signal when the
time specified as the run/power-on warning time (b034) is exceeded.
Item
Run/power-on warning time
(1) Operation time over (RNT) signal
To use this signal function, assign function "11" (RNT) to one of the intelligent output terminals [11] (C021)
and the alarm relay terminal (C026).
Specify the run/power-on warning time (b034).
(2) Plug-in time over (ONT) signal
To use this signal function, assign function "12" (ONT) to one of the intelligent output terminals [11] (C021)
and the alarm relay terminal (C026).
Specify the run/power-on warning time (b034).
7.8.11 0Hz speed detection signal (ZS)
The inverter outputs the 0 Hz speed detection signal when the inverter output frequency falls below the
threshold frequency specified as the zero speed detection level (C063).
To use this signal function, assign function "21" (ZS) to one of the intelligent output terminals [11] (C021)
and the alarm relay terminal (C026).
