Overview of parameters of the digital electronic modules
Group diagnostics
The parameter "Group diagnostics" enables or disables the generation and transmission of
module-specific diagnostic alarms (e.g. short-circuit to M) of the module to the CPU.
The "Fault" and "Parameter assignment error" diagnostic functions are always enabled
independent of the group diagnostics.
Diagnostics: Wire break
If this parameter is enabled, the system generates a diagnostics event when a wire break is
detected.
Diagnostics: Missing load voltage L+
If this parameter is enabled, the check for missing load voltage is enabled for the affected
module.
Diagnostics: Short-circuit
If this parameter is enabled, the check for short-circuit is enabled for the module.
Diagnostics: Short-circuit to L+
If this parameter is enabled, the system generates a diagnostics event when a short-circuit to
L+ is detected.
Diagnostics: Short-circuit to M (DI)
If this parameter is enabled, the check for short-circuit of the encoder supply to ground is
enabled for the module.
Diagnostics: Short-circuit to M (DO)
If this parameter is enabled, the check for short-circuit of the output signal to ground is
enabled for the module.
Diagnostics: Short-circuit to M 24 V encoder supply
If this parameter is enabled, the system generates a diagnostics event when it detects a
short-circuit of the encoder supply to ground.
