Sysmac CQM1 User Manual

2-1 CPU Unit
The CQM1 is a compact, high-speed PC made up of a CPU Unit, Power Supply
Unit, and I/O Units that together provide up to 256 total I/O points. These compo-
nents lock together at the sides, allowing simple changes in the size and capac-
ity of the PC. There are six types of CPU Unit, shown in the table below. All of the
CPU Units except for the CQM1-CPU11-E have a built-in RS-232C interface.

CQM1-CPU11-E and CQM1-CPU21-E CPU Units provide a maximum of 128
I/O points. The only difference between the two models is the RS-232C port
that is added to the CQM1-CPU21-E.
The CQM1-CPU42-EV1 CPU Unit provides a built-in analog setting function.
It has four dedicated volume controls, and their respective values (0 to 200
BCD) appear in words 220 to 223. This function can be used for operations
such as changing timer and counter set values during operation.
The CQM1-CPU43-EV1 CPU Unit provides a built-in pulse input and output
function. It has two dedicated ports for high-speed counting of up to 25-kHz
two-phase pulse inputs from a device such as a rotary encoder and output-
ting up to 50-kHz pulses to a device such as a stepping motor.
The CQM1-CPU44-EV1 has two ABS interfaces (absolute encoder inter-
faces) that can directly receive inputs from absolute-type rotary encoders.
Note In this manual, CQM1-CPU11-E/21-E CPU Units are referred to as “standard
CPU Units,” and CQM1-CPU41-EV1/42-EV1/43-EV1/44-EV1 CPU Units are
referred to as “highly functional, large-capacity CPU Units.”
