AKD-N Installation | 7 Technical description and data
7.12 LED Codes
The built-in LED indicates the status of the drive after the 24 V supply for AKD-C is switched
on. If the AKD-C service connection to the PC or to the PAC doesn't work, then the LED is
the only way to get information.
DANGER
High voltage up to 900 V
There is a danger of serious personal injury or death by electrical shock or
electrical arcing. The built-in LED does
not
indicate the real voltage level.
Always measure the voltage in the DC bus link at connector X14 at
AKD-C and
wait until the voltage is below 50 V before handling any component in
the decentral servo system.
The LED delivers information with three colors (red, green, yellow) and blink frequency. Spe-
cialist can analyze the blink frequency, more information to that can be found in the
WorkBench online help.
