1. INTRODUCTION
The hardware high-speed counter block is a 2-phase 50 kHz high-speed counter. It is a special function
block for the FX , FX

• FROM/TO instruction transfers the PLC data (i.e. parameters, comparing value and present value).
• The FX -1HC occupies 8 points of I/O on the FX
2N
can be allocated from either inputs or outputs.
• Differential-Line-Driver (AM26C31 or equivalent) and open collector output encoders are available for
FX -1HC.

• The source of your input signal should be a 1 or 2 phase encoder. A 5V, 12V, or 24V power source can
be used. An initial value setting command input (PRESET) and a count prohibit command input (DIS-
ABLE) are also available.
• The FX -1HC has two outputs. When the counter value coincides with an output compare value, the
2N
appropriate output is set ON. The output transistors are individually isolated to allow either sink or
source connection methods.
• Various counter modes, such as 1-phase or 2-phase, 16-bit or 32-bit modes, can be selected using
commands from the PLC. Allow the FX
