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.

(Pulse outputs can be used with transistor outputs only, they cannot be used with
relay outputs.)
