Features and Main Functions
Section 1-1
Full Complement of High-
speed Counter Functions 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 (counter 0) only, and you must select whether to use input frequency
monitoring or counter 3; you cannot use both).
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 (CPU Units
with Transistor
Outputs Only)
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.
• Pulse outputs for 2 axes at 100 kHz maximum are provided as standard
features. (See note.)
• For CP1L-J PLCs, pulse outputs for 2 axes at 20 kHz maximum are pro-
vided as standard features. (See note.)
Note The instruction used to control each output point determines
whether it is used as a normal output, pulse output, or PWM output.
Full Complement of Pulse
Output Functions Select CW/CCW Pulse Outputs or Pulse Plus Direction Outputs for the
Pulse Outputs
The pulse outputs can be selected to match the pulse input specifications of
the motor driver.
Easy Positioning with Absolute Coordinate System Using Automatic
Direction Setting
For operations in an absolute coordinate system (i.e., when the origin is
established or when the PV is changed by the INI instruction), the CW/CCW
direction can be automatically set when PULSE OUTPUT instructions are
executed according to whether the specified number of output pulses is more
or less than the pulse output PV.
16 built-in outputs
