device.
X20
Signal Name Status Description
DO1 Brake chopper
status
LOW Brake chopper not active or 24−V supply voltage off
HIGH Brake chopper active
DO2 Status message LOW l 24−V supply voltage is off
l Fault: Heatsink overtemperature
– no acknowledgement required
l Fault: Brake IGBT overcurrent/short circuit
– acknowledgement required:
HIGH 24−V supply voltage ok, module ready for operation
Acknowledgement of the status messages of the power supply modules by means of:
ƒ Applying of 24 V (HIGH) at input DI2.
ƒ Short−time switch−off of the 24−V supply voltage
– If the voltage supply cannot be switched off, terminal X21 can be unplugged
instead.
If the status cannot be acknowledged, the "overtemperature" or "overcurrent/short
circuit" fault persists.
9.1.2 Axis modules
To diagnose the axis modules, errors and warnings are mapped in "error codes" according
to the CiA 301/402 standard. Additionally, a history is available enabling a central logbook
to be set up in the control system. More detailed information can be found in the software
manual or in the online help.
