Pulse Outputs
Section 5-3
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.
Origin Search Error Processing
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.)

CCW Limit Stop
Input Signal
0101
Stopped due to a CCW limit sig-
nal input.
Move in the CW direction.
No Origin Proximity
Input Signal
0200
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.
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.
No effect on
other port
No Origin Input Sig-
nal
0201
The Origin Input Signal was not
received during the origin
search.
Check the wiring of the Origin
Input Signal as well as the PLC
Setup's Origin 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.
