Pulse Output Functions
The 3G3MV-P10CDT has two pulse outputs. By means of a selection in the
PLC Setup, these outputs can be used as two single-phase outputs without
acceleration and deceleration, two variable duty ratio pulse outputs, or pulse
outputs with trapezoidal acceleration/deceleration (one pulse + direction out-
put and one up/ down pulse output). The pulse output PV coordinate system
can also be specified in the PLC 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 out-
puts are stopped by an instruction.
For more details please refer to Programming Manual W353

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
µ
s
max.) and OFF response time (40
µ
s max.).
