4.2 Explanation of the parameters
Diagnostics: Missing load voltage 2L+
Enabling of the diagnostics for missing or insufficient load voltage 2L+.
Diagnostics: Short-circuit to ground
Enabling of the diagnostics for short-circuit of the encoder supply or output to ground.
Freely assignable channel n
With this parameter, you set whether the channel is to be operated as an input or output.
Reaction to CPU/master STOP
With this parameter, you set the reaction of the digital outputs of the digital input/
digital output module after a CPU/master STOP:
•
Shut down: The digital output is de-energized.
• Keep last value: The last value of the digital output remains activated.
• Output substitute value: The module outputs a configured substitute value.
Substitute value channel 0 … 7
With this parameter, you set substitute values for the digital outputs.
