*1 SPF basic unit has a built-in hardware high-speed counter for eight channels. To use the high-speed counter, set the
channels to be used (CH0 t CH7) and counter mode (pulse input format and input to be used) on the "High-speed counter
setting" screen in the system definition. Since the input to be used differs depending on the basic unit type, the number of
usable channels is determined by the basic unit type and system definition setting.
*2 The counting speed of the high-speed counter is determined by the response speed of the input address to be used. The
input response speed of SPF basic unit differs depending on the basic unit type and input to be used.
For details, refer to "2-2 Input Specifications".
*3 For details, refer to "2-3 Special Relay/Register Specifications."
*4 For details, refer to "3-2 High-speed Counter FB."

Max. 8 channels
• 90-degree phase-differential two-phase signal
• Forward pulse (A-phase) / Reverse pulse (B-phase)
• Command pulse (A-phase) / Direction signal (B-phase)
Open collector (24V DC)
High-functionality type Basic unit: 200kHz, 20kHz
Standard type Basic unit: 100kHz, 20kHz
Note: When used in "90-degree phase-differential two-phase signal" mode, the counting speed
becomes half.

Count can be stopped from external input or an application.
• Count enable/stop input a Set an arbitrary input on the basic unit.
• Current value clear input a Set an arbitrary input on the basic unit.
• Current value latch input a Set an arbitrary input on the basic unit.
The current value can be cleared to 0 from external input or an application.
The current value can be latched from external input or an application.
The dedicated instruction (W_HSC) is used.
The dedicated instruction (W_HSC) is used.
Max. 8
Channels not used as a high-speed counter can be used as a delay timer (free run counter)
with 0.1ms of base time.
