AKD-N Installation | 6 Technical description and data
6.12 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
The built-in LED does not safely indicate the real voltage level.
If connectors are unplugged or contacts are touched, there is a danger of
electrical arcing with damage to contacts and serious personal injury.
Always measure the voltage in the DC bus link at connector X14 at AKD-
C and wait until the voltage is below 60 V before handling any com-
ponent 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.
