Pulse Outputs
Section 5-3
Restrictions
The motor can be moved even if the origin position has not been determined
with the origin search function, but positioning operations will be limited as fol-
lows:
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.)
