Run/power ON warning time
Inverter outputs the operation time over (RNT) or the plug-in time over (ONT) signal
when the time specified as the run/power ON warning time (b034) is exceeded.

(1) Operation time over (RNT) signal
To use this signal function, assign function “11 (RNT)” to one of the intelligent
output terminals [11] to [12] (C021 to C022), or to the alarm relay output (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] to [12] (C021 to C022), or to the alarm relay output (C026).
Specify the run/power-ON warning time (b034).
Rotation restriction related parameters
Rotation direction restriction: b035 – The rotation direction restriction function allows
you to restrict the direction of the motor rotation. This function is effective regardless of
the specification of operation command input device (e.g., control terminal or integrated
operator). If an operation command to drive the motor in a restricted direction is given,
the inverter (display) shows ( ).
Reverse run protection: b046 – The reverse run protection function is effective when
“03 (sensorless vector control)” or “04 (0-SLV)” is specified for the V/F characteristic
selection (A044). For control reasons, especially during motor operation at low speed, the
inverter may output a frequency that instructs the motor to rotate in the direction
opposite to that specified by the operation command.
