■ALMWNG (Malfunction/Warning)
When an alarm occurs, ALMWNG turns off.
When a warning occurs (except for [AL. 09F Battery warning]), ALMWNG turns on and off repeatedly approximately every 1 s.
When neither an alarm nor a warning is occurring, ALMWNG will turn on in 2.5 s to 3.5 s after power-on.
■BW9F (AL9F warning)
When [AL. 9F Battery warning] occurs, BW9F turns on.
In the absolute position detection system with a battery-less ABS encoder, BW9F is always off.
■PENS (Command pulse train input permitted)
While the command pulse train input can be received, PENS is on.
In addition, if PEN has not been assigned to the input device, PENS is on. The output device is available on servo amplifiers
with firmware version A5 or later.
