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
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.
Basic function
Positions each axis independently
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.
Positions using two axes, following an
arc from the specified starting point to
the specified end point.
Adds another axis in parallel to circular
interpolation.
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.
Used for winding machine operations.
Any of the following modes can be
specified for positioning operations:
Stop Mode, Pass Mode, or In-position
Check OFF Mode.
Changes servo system parameters
using G language.
Outputs an M code or D code at a
specified position during axis operation.
Executes an interrupt program with the
D code (0 to 255) as the interrupt
program number.
Changes the speed by applying a
specified factor.
