8-11 Pulse Output Patterns
The pulse output function of the Pulse I/O Module enables operation in Continuous Mode, for which the
number of output pluses is not specified, or in Independent Mode, for which the number of output
pulses is specified. Continuous Mode is used for speed control and Independent Mode is used for posi-
tioning.
The following operations can be performed in Continuous Mode by combining instructions.
