Interrupt
processing External interrupts 4 (Also used for external interrupt inputs in counter mode and quick-response
inputs.)
Interval timer
interrupts 1 (Scheduled Interrupt Mode or Single Interrupt Mode)
High-speed High-speed counter 1 (20 kHz single-phase or 5 kHz two-phase (linear count method))
counter Counter interrupt 1 (set value comparison or set-value range comparison)
Interrupt Inputs
(Counter mode) 4 inputs (Also used for interrupt inputs and quick-response inputs.)
Counter interrupts 4 (Also used for the external interrupt inputs and quick-response inputs.)
Pulse output 2 points with no acceleration/deceleration, 10 Hz to 10 kHz each, and no direction
control.
1 point with trapezoidal acceleration/deceleration, 10 Hz to 10 kHz, and direction
control.
2 points with variable duty-ratio outputs.
(Pulse outputs can be used with transistor outputs only, they cannot be used with
relay outputs.)
