The CPM2A/CPM2C has two pulse outputs. By means of a selection in the PC
Setup, these outputs can be used as two single-phase outputs without accelera-
tion and deceleration, two variable duty ratio pulse outputs, or pulse outputs with
trapezoidal acceleration/deceleration (one pulse + direction output and one up/
down pulse output). The pulse output PV coordinate system can also be speci-
fied in the PC Setup as either relative or absolute.
There are two pulse output modes: Independent mode, in which outputs are
stopped at a preset amount of pulses, and continuous mode, in which outputs
are stopped by an instruction.
Note To use pulse outputs, it is necessary to use a CPU Unit with transistor outputs,
i.e., either a CPM2A-
The following diagram shows the configuration for a CPM2A, but the configura-
tion for a CPM2C is identical.
