Features and Main Functions
Section 1-1
Target Speed, Acceleration Rate, and Deceleration Rate Changes during
Acceleration or Deceleration
When a PULSE OUTPUT instruction with trapezoidal acceleration and decel-
eration is executed (for speed control or positioning), the target speed and
acceleration and deceleration rates can be changed during acceleration or
deceleration.
Lighting and Power Control by Outputting Variable Duty Ratio Pulses
Operations, such as lighting and power control, can be handled by outputting
variable duty ratio pulse (PWM) output signals from the CPU Unit's built-in
outputs.
Origin Searches (All
Models)
Origin Search and Origin Return Operations Using a Single Instruction
An accurate origin search combining all I/O signals (origin proximity input sig-
nal, origin input signal, positioning completed signal, error counter reset out-
put, etc.) can be executed with a single instruction. It is also possible to move
directly to an established origin using an origin return operation.
Input Interrupts (All
Models)
In direct mode, an interrupt task can be started when a built-in input turns ON
or OFF. In counter mode, the rising or falling edges of built-in inputs can be
counted, and an interrupt task started when the count reaches a specified
value. The maximum number of points is 8 for X and XA CPU Units and 6 for
Y CPU Units. (See note.)
Note
For each input point, a selection in the PLC Setup determines whether it is to
be used as a normal input, interrupt input, quick-response input, or high-
speed counter. The interrupt input response frequency in counter mode must
be 5 kHz or less total for all interrupts.
Quick-response
Inputs (All Models)
By using quick-response inputs, built-in inputs up to a minimum input signal
width of 30
µ
s can be read regardless of the cycle time.
The maximum number of points is 8 for X and XA CPU Units and 6 for Y CPU
Units. (See note.)
Note
For each input, a PLC Setup parameter determines whether it is to be used as
a normal input, interrupt input, quick-response input, or high-speed counter.
Analog I/O Function
(XA CPU Units Only)
XA CPU Units have analog I/O functionality, with 4 analog voltage/current
inputs and 2 analog voltage/current outputs built in.
• A wide range of applications is possible at a resolution of 6,000 or 12,000.
• Application is also possible for process-control sensor input or Inverter
control without using Expansion I/O Units.
