12 Pulse Outputs

12-11Pulse Output Pattern

The CP2E CPU Unit's pulse output function enables operation in Continuous Mode, for which the num-
ber 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 positioning.

12-11-1 Speed Control (Continuous Mode)

The following operations can be performed in Continuous Mode by combining instructions.
Starting a Pulse Output
Example
Operation
application
Output with Changing the
specified speed (fre-
speed quency) in one
step
Output with Accelerating the
specified speed
acceleration (frequency) at a
and speed fixed rate
Changing Settings
Example
