Output Stopped Error Flags
ON when an error occurred while outputting
pulses in the origin search function.
Stop Error Codes
When a Pulse Output Stop Error occurs, the error code is stored in that
pulse outputs corresponding Stop Error Code word.

An origin search will not be started unless the origin search proximity speed is
less than the origin search high speed and unless the origin search/return ini-
tial speed is less than the origin search proximity speed.
The CP1H CPU Unit's pulse output function performs a basic error check
before starting to output pulses (when the instruction is executed) and will not
output pulses if the settings are incorrect. There are other errors that can
occur with the origin search function during pulse output, which may stop the
pulse output.
If an error occurs that stops pulse output, the pulse output's Output Stopped
Error Flag will be turned ON and the Pulse Output Stop Error Code will be
written to Error Code word. Use these flags and error codes to identify the
cause of the error.
The Pulse Output Stop Errors will not affect the CPU Unit's operating status.
(The Pulse Output Stop Errors do not cause a fatal or non-fatal error in the
CPU Unit.)
Function
0: No error
1: Stop error occurred.
Likely cause
Stopped due to a CW limit signal
input.
Stopped due to a CCW limit sig-
nal input.
The parameters indicate that the
Origin Proximity Input Signal is
being used, but a Origin Proxim-
ity Input Signal was not received
during the origin search.
The Origin Input Signal was not
received during the origin
search.
Operation
Cannot be used.
Outputs the specified number of pulses after setting the
current position to 0.

Move in the CW direction.
Check the wiring of the Origin
Proximity Input Signal as well as
the PLC Setup's Origin Proxim-
ity Input Signal Type setting (NC
or NO) and execute the origin
search again. Turn the power
supply OFF and then ON if the
signal type setting was changed.
