Types of Pulse Outputs

Note 1. With single-phase pulse outputs, pulse outputs 0 and 1 can each be output
independently.
2. Pulse outputs can be accelerated or decelerated in units of 10 Hz every
10 ms.
3. Actual pulses are affected by the transistor output's ON response time
(20 s max.) and OFF response time (40 s max.).
The following table shows the relationships between the high-speed counter
and the CPM2A/CPM2C's other functions.

Note The number of simultaneous outputs varies according to the type of pulse out-
put, as shown in the following table.

Up to two points can be output simultaneously with only single-phase pulse out-
puts, so two-point output is possible when fixed duty ratio and variable duty ratio
are used in combination.
Outputs are possible for only one point at a time with pulse + direction outputs
and up/down pulse outputs, so no other pulses can be output.
There are three types of pulse outputs: Single-phase pulse outputs without ac-
celeration and deceleration, variable duty ratio pulse outputs, and single-phase
pulse outputs with trapezoidal acceleration and deceleration.
