One CJ1W-MCH71 Motion Control Unit requires the space of three standard Unit.
Occupies the area for 1 unit (25 words)
For units and tasks: 11 to 25 words (Depending on the number of motion tasks)
Occupies the area for 1 unit (100 words)
For units and tasks: 32 to 74 words (Depending on the number of motion tasks)
For axes: 0-64 words (Depending on the greatest number of the axis used)
For axes: 0-128 words (Depending on the greatest number of the axis used)
For General I/O: 0-1280 words (Depending on setting)
MECHATROLINK-II below supported
• W-series Servo Driver with built-in communications functions
• W-series Servo Driver (OMRON) + Communications I/F Unit (YASKAWA)
• Various I/O units (YASKAWA)
• SMARTSTEP Junior Servo Drive
Up to 30 nodes
* When MECHATROLINK-II devices are connected up to 16 nodes (within 30 m) or 15 nodes (within 50m), a
repeater unit is not required. A repeater unit is required to connect MECHATROLINK-II devices more than the
cases described above.
Dedicated motion control language
MECHATROLINK-II
• Position commands, Speed commands, Torque commands
32 axes max.
Physical axes/Virtual axes: 30 axes max. (Either can be selected for each axis)
Dedicated for virtual axes: 2 axes
RUN mode, CPU mode, Tool mode/System (Depending on the tool)
Automatic mode: Executing built-in programs of MC Unit controls motion.
Manual mode: Executing commands from CPU Unit (PC interface area) controls motion.
Note: The Automatic or Manual Mode is set according to the PC Interface area of the CPU Unit.
1, 0.1, 0.01, 0.001, 0.0001
mm, inch, deg, pulse
-2147483647 to 2147483647 pulses (signed 32-bit)
Mode for unlimited axes feeding is possible.
Example: With 16-bit encoder (65536 pulse/rev), Minimum setting unit: 0.001 mm, 10 mm/rev, the position
command value range will be from -327679999 to 327679999 command units.
Executes Servo driver lock or unlock
Executes continuous feeding independently for each axis, by means of speed set in system parameter x over-
ride.
Feeds a specified distance for a specified axis.
Defines the machines origin according to the search method set in the system parameters.
Forcibly sets the present position to 0 to establish it as the origin.
Sets the origin when an absolute encoder is used.
Offset value: Signed 32-bit (pulses)
Forcibly resets the error counter to 0.
Sets the present position to a user-specified value.
Prohibits the output of motion commands to the axes.
Executes the motion program one block at a time.
Switches between auto mode and manual mode.
