11.2.2 Error Output
If the following limit values are exceeded or not reached, the output is activated. At the
same time, the motor current is switched off:
Limits
Error message displayed in
ServiceBus:
Motor current
> 25.2 A
overload
Supply voltage
< 40 V or > 160 V
power supply fault
Heat sink
temperature
> 85°C
overtemperature
The error is displayed in the status display (red LED) in the ServiceBus-Comm
TM
:
The red LED OVERLOAD shines e.g. in case of motor short-circuit or if the time delay
during deceleration is too long.
The red LED SUPPLY FAILURE shines, when the supply voltage is out of the admissible
range 40...160 V. Danger of destroying the component in case of 200 V supply voltage!
The power stage needs sufficient time for cooling in case of ‚OVERTEMPERATURE’
(>85°C).
The supply voltage must be powered off to reset the protective circuit after activation.
Switch on again only then, as soon as all LEDs are off!
Alternatively, it is possible to plug the J1 jumper on position Reset and activate the Reset
signal (low active) via pin 45a of the connector.
