Displays, diagnostics
Several LEDs are assigned to each port.
The following figure shows the position of the LEDs on the housing.
LEDs on X001
LED | Meaning | |
|---|---|---|
RUN | Status of the terminal in the EtherCAT network. | |
off | Status "Init" | |
flashes | Status "Pre-Operational" | |
Single flash | Status "Safe-Operational" | |
lit | Status "Operational" | |
A1 | Status of Touch Probe "IN 1A": connector X001, pin 3. | |
A2 | Status of Touch Probe "IN 2A": connector X001, pin 4. | |
B1 | Status of Touch Probe "IN 1B": connector X001, pin 8. | |
B2 | Status of Touch Probe "IN 2B": connector X001, pin 9. | |
LEDs at X002 and X003
LED | Meaning | |
|---|---|---|
OK | off | The axis is switched off. |
flashing green | An OCT encoder is searched for or initialized. | |
green illuminated | The axis is switched on. | |
flashes orange | Warning + OCT encoder is being searched for or initialized. | |
orange illuminated | Warning. See chapter Diagnosis. | |
flashes red | Error + OCT encoder is searched for or initialized. | |
red illuminated | Error. If the “LIM” LED also lights up red: special case, see below. | |
LIM | orange illuminated | Internal limitation active; e.g.
|
red illuminated | If the “OK” LED also lights up red: special case, see below. | |
S | Lights up green | No safety error. (only ELM72xx-901x) |
Lights up red | The axis is in the state "STO". (only ELM72xx-901x) | |
Special case: both LEDs "OK" and "LIM" light up permanently red. This means that the control voltage US was unexpectedly switched off during operation.
LEDs on X004
LED | Meaning | |
|---|---|---|
48V 1) | green illuminated | The DC link voltage is applied to connector X004. |
Up | green illuminated | The electronics supply voltage UP = 24 VDC is applied to the power contacts. |
1) The LED is labeled "48V". But it also lights up when another DC link voltage is connected that meets the specifications. See chapter General technical data.
