Interrupt processing
External interrupts: 4
(Shared by the external interrupt inputs (counter mode) and the quick-response inputs.)
Interval timer interrupts
1 (Scheduled Interrupt Mode or Single Interrupt Mode)
High-speed counter
One high-speed counter: 20 kHz single-phase or 5 kHz two-phase (linear count method)
Counter interrupt: 1 (set value comparison or set-value range comparison)
Interrupt Inputs
(Counter mode)
Four inputs (Shared by the external interrupt inputs (counter mode) and the
quick-response inputs.)
Counter interrupts: 4 (Shared by the external interrupt inputs and quick-response inputs.)
Pulse output
Two points with no acceleration/deceleration, 10 Hz to 10 kHz each, and no direction
control.
One point with trapezoid acceleration/deceleration, 10 Hz to 10 kHz, and direction control.
Two points with variable duty-ratio outputs.
(Pulse outputs can be used with transistor outputs only, they cannot be used with relay
outputs.)
Synchronized pulse control
One point:
A pulse output can be created by combining the high-speed counter with pulse outputs
and multiplying the frequency of the input pulses from the high-speed counter by a fixed
factor.
(This output is possible with transistor outputs only, it cannot be used with relay outputs.)
Quick-response inputs
Four points (Min. input pulse width: 50
µ
s max.)
Analog controls
2 controls, setting range: 0 to 200
