Overview
This section describes the operations required for basic positioning with an
MC Unit, and explains how to use them. It also explains the functions that
have been newly added or changed from those of the earlier C200H-MC221
MC Unit. For explanations of other functions, refer to
3-3 System Parameters
,
5-3 PLC Interface Area
, and
7-2 G Language Overview
.
There are four ways to execute operations, as follows:
• Running a G-language program
• Executing operations with the PLC Interface Area in the CPU Unit
• Executing operations with the Command Area
• Setting system parameters
Notation
The bit status is indicated as follows in the explanations of positioning opera-
tions:
↑
:
A transition in the bit from 0 (OFF) to 1 (ON) (See note.)
↓
:
A transition in the bit from 1 (ON) to 0 (OFF) (See note.)
1:
ON
0:
OFF
Note
Transitions in bits are determined in the MC Unit and are not always detect-
able when using the DIFU and DIFD instructions in the program in the CPU
Unit.

PTP control
Positions each axis independently
Automatic
G language (G00)
327
Linear interpolation
Performs linear interpolation on 1, 2, 3,
or 4 axes (1 or 2 axes for MC221).
The specified axes move
simultaneously.
The feed rate can be specified.
Automatic
G language (G01)
328
Circular interpolation
Positions using two axes, following an
arc from the specified starting point to
the specified end point.
Automatic
G language (G02/G03)
331
Helical circular
interpolation
Adds another axis in parallel to circular
interpolation.
Automatic
G language (G02/G03)
332
Interrupt feeding
Feeds along an axis for a fixed distance
when an external interrupt is input.
Feeding is also possible by specifying a
given travel distance even when no
interrupt is input.
Automatic
G language (G31)
334
Traverse
Used for winding machine operations.
Automatic
G language (G32)
336
Operating mode
Any of the following modes can be
specified for positioning operations:
Stop Mode, Pass Mode, or In-position
Check OFF Mode.
Automatic
G language (G10, G11,
G13), system setup
337
Change parameter
Changes servo system parameters
using G language.
Automatic
G language (G69)
345
Stopover
Outputs an M code or D code at a
specified position during axis operation.
Automatic
G language (G00, G01)
346
CPU Unit interrupt
processing
Executes an interrupt program with the
D code (0 to 255) as the interrupt
program number.
Automatic
G language (D code
output)
348
Override
Changes the speed by applying a
specified factor.
Automatic,
manual
Bit designation
