3.3.11 Error output
CAUTION!
Electronic damage!
The fault output is configured as an output in the factory. Before connecting as an input, the fault
pin must have been configured accordingly. The configuration must be saved (see communication
and function manual / commissioning chapter).
The electronics can be damaged if a voltage is applied to the fault output while it is not configured
as the input.
f
Check the fault output setting before applying a voltage.
The voltage applied to the fault output must never exceed the voltage supply of the Motion Controller.
The supply voltages of the sensors must not exceed the supply voltage of the Motion Controller (e.g.
in case of separate supply systems 24 V / 12 V).
f
Match the supply voltages of the sensors and the Motion Controller to each other.
The supply voltage of the sensors must never be switched on while the supply voltage of the Motion
Controller is switched off.
f
Ensure that the supply voltage of the sensors cannot be switched on independently of the supply
voltage of the Motion Controller.

Error output
The error output is characterised by the following characteristics:
Circuit that switches to GND (Open Collector)
Output resistance in open state (High Level): 100 k
The circuit is open in the event of error (High Level)
Output current limited to approx. 30 mA, voltage in open state must not exceed the supply
voltage (maximum U
B
)
Short-circuit proof
Depending on the option, the Fault error output connection can also be configured for other functions:
Pulse output
Digital output (freely programmable)
Homing or digital input
Rotational direction input
NOTE
Note
If the error output is used as an input, we recommended connecting an external resistor
(100
Ω
/ 0,25 Watt) in series.
