■ Switch to the ARM Mode with ARM Command
１
Input enabled signals (trailing) for the ARM command

Switch to the ARM mode from the STOP and VIEW modes.

Even in an ARM command is input in the PLAY, LOOP, SAVE (USB save), or
DOWNLOAD (downloaded and saved with HXLink) modes, it doesn’t switch to the
ARM mode.
ARM Status Signals

The ARM status provides open collector output so waveforms cannot be observed if voltage is
not applied from an external power source.

Open collector output, isolation, maximum applied voltage ： 50VDC


Output signals are signals indicating the ARM mode, and it is possible to select either L(NEGA) / H (POSI)
of the polarity settings as the output level during ARM.
Example of ARM command input ・ ARM status output
The polarities of the ARM command input and ARM status output are both negative （
