ity, to 512 points (from 256 points); and the data memory capacity, to
6 Kwords of DM and 6 Kwords of EM (from 6 Kwords of DM only).
• A 16-Kword Memory Cassette can be mounted in the CQM1H to handle
large user programs or more data. These features ensure a higher level
of machine control and greater ease of use.
Increased Functionality
with Inner Boards
The CQM1H features Inner Boards that allow serial communications, multi-
point high-speed counter (rotary encoder) inputs, simple positioning (trapezoi-
dal acceleration/deceleration pulse outputs), speed changes, PWM (variable
duty-factor pulse) outputs, absolute rotary encoder inputs, analog I/O (4
inputs, 2 outputs), and analog settings.
A Serial Communications Board, High-speed Counter Board, Pulse I/O
Board, Absolute Encoder Interface Board, Analog I/O Board, and Analog Set-
ting Board are available. These Inner Boards can be combined, mounted and
used as required for the machine being controlled. (There are mounting
restrictions for some of the Inner Boards.)
Note The CPU Unit also provides16 built-in inputs, as well as high-speed counter
and input interrupt functions. Pulse outputs are also supported using a stan-
dard Transistor Output Unit.
