Description of Features
Multi-tasking G Language
The MC Unit is provided with a multi-tasking G language, which is the opti-
mum language for motion control. The G language makes it simple to create
programs for multi-axis control, without placing a burden on the CPU Unit’s
ladder diagram program.
Simple and Fast Traverse
Operations
Commands for 2-axis traverse operations enable simple and fast traverse
operations.
Fast Pick-and-place
Operations
After a positioning command has been output, the in-position check OFF
function allows the next positioning operation to be started without waiting for
the first positioning operation to be completed. This makes it possible to per-
form high-speed pick-and-place operations.
Supports Absolute
Encoders
The MC Unit is compatible with absolute encoders (such as the OMNUC W
Series) as a standard feature, eliminating the need to perform an origin
search. Incremental encoders can be used as well.
High-speed Response to
Start Commands from
CPU Unit
The response time from when a start command is received from the CPU Unit
until the command voltage is output from the MC Unit is 8 ms for two axes and
12 ms for four axes (MC421 only). This is 1.5 times faster than the previous
models.
Two-axis MC Unit
This function applies to the X axis when a 2-axis, 1-task configuration is used.
Four-axis MC Unit
This function applies to the X axis when a 4-axis, 1-task configuration is used.
500-kp/s Encoder
Response Frequency
The maximum feedback encoder response frequency is 500 kp/s, so the MC
Unit can be used with high-speed and high-precision servomotors. This is
double the response frequency of the earlier models.
CPU Unit Interrupts
A CPU Unit external interrupt task can be started by outputting a D code
(interrupt code) for the CPU Unit when positioning is completed or when pass-
ing through a particular position. This feature is ideal for high-speed synchro-
nization between the MC Unit and CPU Unit.
Windows-based MC
Support Software
Single-port Multi-access Function
A Windows-based Support Software package called CX-Motion can be used
on the same computer and through the same port as the CX-Programmer,
enabling multiple programming environments on a single computer.
Servo Information Trace Function
Speed reference values, the present speed, and the error counter can be
traced with specified starting conditions and a specified sampling period using
the MC Support Software. Up to 500 items can be traced, making it easy to
adjust the servo system.
Automatic Loading Function
When it is necessary to use more programs or position data than can be
stored in the MC Unit, programs or position data stored in an external memory
device at the computer where the MC Support Software is installed can be
automatically downloaded to the MC Unit’s internal memory.
Data Creation Using
Teaching Box
In addition to entering numbers in the Position Data Edit Window of the MC
Support Software (CX-Motion), it is possible to create position data by using
the Teaching Box to teach positions while actually moving the machinery.
Operate with MPG
Positioning and simple sync operations can be performed using an MPG
(manual pulse generator).
