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.
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 can find information about causes and responses in the respective operating mode
descriptions and in the section "Technical Specifications for Programming, Reference Lists
(Page 353)".
The pulse output error detected is displayed for the relevant channel with the ERR_PULS
feedback bit.
Short circuit of the encoder supply 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.
A drop in the 24 V supply voltage can also result in a short circuit message.
Short circuit digital output ERR_DO
The 2PULSE detects a short circuit on the digital output of the channel.
The short circuit detected is displayed for the relevant channel with the ERR_DO feedback
bit.
Note
If a short circuit occurs, the digital output is able to briefly supply a current substantially
higher than the rated value.
