Error Signal
Function
This is the encoder input signal. This signal is only used
when you use an encoder trigger.
Function
This signal tells when new commands and other external
inputs cannot be acknowledged during processing of other
external inputs.
Just because this signal is ON does not necessarily mean
that a command is being executed. To check whether a
command is being executed, access the Command
Completion (FLG) signal.
The FH/FZ5 uses this signal to tell the user (PLC) that
command execution has been completed.
This signal tells the timing to load the output data to the
User (PLC).
Data output is enabled when this signal is ON.
This signal indicates when the STEP (Measurement
Trigger) signal or the Trigger signal can be input.
When using the multi-input function, the succeeding STEP
or Trigger signals are accepted only after this signal turns
ON.
This signal gives the results of the overall judgement.
These signals are used to output parallel data and parallel
judgements through a parallel interface.
This signal tells when execution of a command that was
executed during execution of PLC Link or fieldbus flow
control has been completed.
This signal tells when a command that was input during
execution of PLC Link or fieldbus flow control is being
executed.
This signal tells when input of a command can be
acknowledged during execution of PLC Link or fieldbus
flow control.
The FH/FZ5 uses this signal to acknowledge reception of a
Trigger signal.
This signal tells when control command can be executed.
The FH/FZ5 provides notification with this signal when it
detects the following errors.
Refer to Error Messages and Troubleshooting in the
Vision System FH/FZ5 Series User's Manual (Cat. No.
Z365).
• Camera connection error
• Battery error
• Fan error
The ERR signal does not turn OFF even after the error is
eliminated. The signal turns OFF only when the error status
is cleared by a control command.
