Features and Main Functions Section 1-1
Full Complement of High-
speed Counter Functions
(All Models)
High-speed Processing for High-speed Counter Present Value (PV)
Target Values or Range Comparison Interrupts
An interrupt task can be started when the count reaches a specified value or
falls within a specified range.
High-speed Counter Input Frequency (Speed) Monitoring
The input pulse frequency can be monitored using the PRV instruction (one
point only).
High-speed Counter PV Holding/Refreshing
It is possible to toggle between holding and refreshing the high-speed counter
PV by turning ON and OFF the High-speed Counter Gate Flag from the ladder
program.
Versatile Pulse
Control (All Models)
Positioning and speed control by a pulse-input servo driver is enabled by out-
putting fixed duty ratio pulse output signals from the CPU Unit's built-in out-
puts.
Four axes (X,Y, Z, and θ) can be controlled. A 1-MHz speed pulse rate is also
possible for Y CPU Units.
• X and XA CPU Units
Pulse outputs for 4 axes at 100 kHz maximum are provided as standard
features. (See note.) (Unit version 1.0 or earlier: Pulse outputs for 2 axes
at 100 kHz maximum and 2 axes at 30 kHz maximum.)
Note The instruction used to control each output point determines
whether it is used as a normal output, pulse output, or PWM output.
