6.1 Overview of Each Functions
This section explains about the functions that use built-in high-speed counter of FP
Σ
.
6.1.1 Three Functions that Use Built-in High-speed Counter
Functions that use built-in high-speed counter
There are three functions available when using the high-speed counter built into the
FP
Σ
.
Roller
Cutter
Tape, lead wire
Cutter blade control signal
START STOP
signal
Inverter
Motor Encoder
Encoder output is input to
the high-speed counter
High-speed counter function
The high-speed counter function counts
external inputs such as those from sensors
or encoders. When the count reaches the
target value, this function turns on/off the
desired output.

Pulse output function
Combined with a commercially available
motor driver, the function enables position-
ing control. With the exclusive instruction,
you can perform trapezoidal control, home
return, and JOG operation.

PWM output function
By using the exclusive instruction, the
PWM output function enables a pulse
output of the desired duty ratio.

When you decrease it...
Heating increases.
