The travel distance of the master axis is superimposed on the slave axis.
This function can be used like the differential gear of a machine.
Only this section is
superimposed.
Superimposed portion
travel distance
ADDAX command
(Travel distance superimpose starts.)
Establishes the origin for a specified axis.
Starts and stops a specified axis at a specified speed.
Forcibly resets the error counter to zero and stops axis operation after com-
pleting a deceleration command.
Changes the present position to specified position data.
Obtains the present position to create position data.
Changes the speed during PTP, linear interpolation, or circular interpolation
operations.
Compensates errors caused by faulty meshing in the mechanical system.
Controls axes such as turntables and conveyors that are fed only in one direc-
tion unlimitedly.
It is possible to execute just one line of a program through single block opera-
tion. It is also possible to run programs without operating the machine system
through Machine Lock.
Backups and restores data using PLC memory cards.
Performs Simple arithmetic operation, Functions, and Logic Operations.
The servo system used by and the internal operations of the MC Unit are
briefly described below.
The MC unit uses the servo system called the semi-closed loop system.
This system is designed to detect actual machine travel distance for a com-
mand value using rotations of the motor and the detected value is fed back to
the MC unit. The unit computes and compensates the error between the com-
mand value and actual travel distance to make it zero.
ADDAXR command
(Travel distance superimpose ends.)
