High-speed I/O Functions
High-speed Counter
This function counts high-speed pulse inputs that cannot be measured in normal user program processing.
Use this function for applications such as positioning control with a rotary encoder or motor control. The FC6A Series MICROSmart
can use single-phase high-speed counters and two-phase high-speed counters. A maximum of six single-phase high-speed
counters and a maximum of two two-phase high-speed counters (three maximum for Plus CPU module only) can be used
simultaneously.
Example: Controlling a motor by counting two-phase pulse input with a high-speed counter
Positioning Control
The FC6A Series MICROSmart can perform positioning control with pulse outputs. The FC6A Series MICROSmart features the PULS
instructions that can generate pulse outputs with configured frequency at the fixed pulse width ratio, JOG instructions, pulse-width
modulation (PWM) instructions that can generate pulse outputs with configured pulse width ratio at a fixed frequency, RAMP
instructions for trapezoidal control, ZRN instructions for zero return operation, and ARAMP instructions that can generate pulse
outputs according to a table in which the changes of the frequency are configured.
The FC6A Series MICROSmart also manages coordinates internally and can increment or decrement coordinates according to the
number of pulses that were output and the direction.
After confirming the origin using the ZRN instruction, the target position can also be specified by absolute position.
Example: Pulse output by the RAMP instruction
Frequency Measurement
This function measures the frequency of pulses input to an input terminal. The frequencies of a maximum of six inputs can be
measured.
