Omron CJ2M-CPU Series User Manual

8 Pulse Outputs
8-84
CJ2M CPU Unit Pulse I/O Module User’s Manual
The pulse output function of the Pulse I/O Module 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 the 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.)
*1 SPED (Independent) to SPED (Independent)
• The number of output pulses cannot be changed.

during acceleration or deceleration.)
• The frequency can be changed. (The target frequency can even be changed during
acceleration or deceleration.)
• The acceleration/deceleration rate can be changed. (The rate can even be changed
during acceleration or deceleration.)
*9 IFEED to IFEED
