4.2 Explanation of the parameters
Diagnostics: Undervoltage 1L+
Enabling of diagnostics for insufficient supply voltage 1L+.
Undervoltage at 1L+ triggers the "Undervoltage" maintenance event. You can find more
information in section Maintenance events (Page 28).
Diagnostics: Short-circuit
Enabling of diagnostics for short-circuit to ground at transducer supply
Diagnostics: Wire break detection and alarm
Activation of wire break detection and enabling of diagnostics. In the event of an interruption
of the line between the encoder and I/O device, a diagnostics alarm is generated.
Effect on the value status
When the parameter is deactivated, wire break detection is switched off. A wire break does
not have an effect on the value status.
Input delay
This parameter can be used to suppress signal interference. Changes to the signal are only
detected if they are present consistently for longer than the set input delay time.
In isochronous mode, the terminal signal is read in at the time T
i (time for reading the input
data). The read-in time T relates to the channel for which an input delay time of 0.05 ms was
configured.
For input channels with longer input delays, the read-in time is moved accordingly. This
means individual channels can be assigned input delays, if necessary, without having a
negative impact on the possible cycle time.
Isochronous configuration is only possible if there an input delay of 0.05 ms is configured for
at least one channel. Otherwise, the "Parameter assignment error" diagnostics alarm is
output.
Hardware interrupt on rising edge
Specifies whether a hardware interrupt is generated for a rising edge on the channel.
Hardware interrupt on falling edge
Specifies whether a hardware interrupt is generated for a falling edge on the channel.
