7-Segment LED Indicator
The 7-segment LED indicator is on the front panel.
When the power is turned on, it shows the node address that is set by the rotary switches. Then the
indication changes in accordance with the setting on the Default Display (Pn700).
If any alarming error occurs, it indicates the error number (Alarm No.xx) as the alarm code. If any
warning situation occurs, it indicates the warning number as the warning code.
*1. When the Safety input error (Alarm No.33.0) occurs, the alarm code is not shown. Instead, "St" flashes.
