1. INTRODUCTION
This user's manual describes specifications, handling, and programming of the
AJ65BT-D62/ D62D/ D62D-S1 high-speed counter modules (hereafter abbreviated as
high-speed counter module) to be used in a CC-Link system.
The high-speed counter module can import and count pulses of a pulse generator
which cannot be imported by a programmable controller CPU.
The high-speed counter module can detect and count up to 400,000 pulses per
second.
The high-speed counter module is available in the following three different types.

The high-speed counter module counts 1-phase and 2-phase pulse inputs as
described below.
1-phase pulse input multiplied by one ............ Counts on the leading edge or trailing
1-phase pulse input multiplied by two ............ Counts on the leading edge and trailing
2-phase pulse input multiplied by one ............ Counts on the leading edge or trailing
2-phase pulse input multiplied by two ........... Counts on the leading edge and trailing
2-phase pulse input multiplied by four ............ Counts on the leading edge and trailing
