Function: Error Detection/Diagnostics

Parameter Assignment Error ERR_PARA
If the 2PULSE cannot identify the parameters as its own, it generates a parameter
assignment error. The two channels are then not assigned parameters.
The 2PULSE slot you configure must match the setup.
Make sure that you only set the 2PULSE parameters that have been described.
Pulse Output Error ERR_PULS
The 2PULSE detects a channel-specific pulse output error in the pulse output, on/off-delay,
and pulse train modes.
You will find information about causes and responses in the respective operating mode
descriptions and the technical specifications for programming.
The pulse output error detected is displayed for the relevant channel with the ERR_PULS
feedback bit.
Encoder Supply Short Circuit ERR_24V
The 2PULSE detects a short circuit in the encoder supply that it makes available at terminals
2 and 6.
The short circuit error detected is displayed for the two channels with the ERR_24V feedback
bit.
Short Circuit of the Digital Output ERR_DO
The 2PULSE detects a short circuit on the digital output of the channel. To do this, you must
enable Diagnostics DO in the parameters.
The short circuit detected is displayed for the relevant channel with the ERR_DO feedback
bit.
Diagnostic Message
In the event of parameter assignment errors or a short circuit in the encoder supply or in the
digital output, 2PULSE generates a diagnostic message for the connected CPU/master. To
do this, you must enable the Group diagnostics parameter.
