In remote operation -- RMT (Function code data = 54)
This output signal comes ON when the inverter switches from local to remote mode.
For details of switching between remote and local modes, refer to user Manual Chapter 4, Section 4.2.2
"Remote and local modes."
Terminal [C1] wire break -- C1OFF (Function code data = 59)
This output signal comes ON when the inverter detects that the input current to terminal [C1] drops below 2 mA
interpreting it as the terminal [C1] wire broken.
Speed valid -- DNZS (Function code data = 70)
This output signal comes ON when the reference or detected speed exceeds the stop frequency specified by
function code F25. It goes OFF when the speed is below the stop frequency for 100 ms or longer.
Under vector control with speed sensor, F38 switches the decision criterion between the reference and detected
speed. Under vector control without speed sensor, the reference speed is used as a decision criterion. ( Refer
to the descriptions of F25 and F38.)
Alarm output (for any alarm) -- ALM (Function code data = 99)
This output signal comes ON if any of the protective functions is activated and the inverter enters Alarm mode.
Enable circuit failure detected -- DECF (Function code data = 101)
This output signal comes ON when the inverter detects a failure of the Enable circuit(*1).
Configure a feedback circuit of the Enable input function as needed to feed back the transistor output of the
DECF-assigned inverter to the reset input of the upper safety relay unit for turning the Enable command off and
shutdown of the inverter output.
