Parameters/address space
4.3 Explanation of the parameters
Short-circuit detection
The diagnostics for short circuit to ground can be configured for the voltage output type.
Short-circuit detection cannot be guaranteed for small output values (between 0.1 V and
+0.1 V).
Wire break detection
The diagnostics for wire break can be configured for the current output type. Wire break
detection cannot be guaranteed for small output values (between -0.2 mA and +0.2 mA).
4.3 Explanation of the parameters
Output type/range channel n
With this parameter, you set the output type or output range for the channel to control the
actuator.
Note
Unused channels
"Deactivate" unused channels in the parameter assignment to improve the power
consumption of the module.
A deactivated channel always returns the value "no voltage or current".
Diagnostics: Actuator supply short circuit to ground
Enabling of the diagnostics if a short-circuit of the actuator supply to ground occurs.
Diagnostics: Short circuit to ground
Enabling of the diagnostics if a short-circuit of the output to ground occurs.
Diagnostics: Wire break
Enabling of the diagnostics if the line to the actuator is broken.
Diagnostics: Underflow
Enabling of the diagnostics when the output value violates the underrange, falls below the
minimum output value or reaches the underflow.
Diagnostics: Overflow
Enabling of the diagnostics when the output value exceeds the overrange.
