7.6 Tandem Learning control function (only 90A7 series)
7.6.1 Summary
Tandem Learning control is a Learning control combined with Tandem control. By means that two motors are
controlled as one axis, and Learning control is added, this function achieves high precision processing in the
special applications.
1) Position Tandem Learning control
Merit : To Achieve high accuracy to learn the position deviation with both sides of long
workpiece which have weak stiffness chucked and driven by two motors.
Applicable machine : Cam grinder, Crank shaft grinder, and etc
2) Torque tandem Learning control
Merit : Large torque of double motor can achieve leaning of the position deviation due to
large cutting torque.
α 400 or α300 requires torque tandem in spite of single motor,
because they have double coils in one motor and use two amplifiers. We call this
“
double coil tandem control” as a special case of torque tandem.
Applicable machine : Helical gear shaper without helical slide, Helical broach machine, Accurate press, etc
