15. USING A LINEAR SERVO MOTOR
15 - 23
(2) Auto tuning function
The auto tuning function during the linear servo motor operation is the same as that of the rotary servo
motor. However, the calculation method of the load to motor mass ratio (J ratio) differs. The load to
motor mass ratio (J ratio) on the linear servo motor is calculated by dividing the load mass by the mass
of the linear servo motor primary side.
Example) Mass of linear servo motor primary side
Load mass (excluding the mass of the linear servo motor primary side)
Mass ratio
= 2 kg
= 4 kg
= 4/2 = 2 times
For the parameters set by the auto tuning function, refer to chapter 6.
POINT
The auto tuning mode 1 may not be performed properly if the following
conditions are not satisfied.
Time to reach 2000 mm/s is the acceleration/deceleration time constant of 5 s
or less.
The linear servo motor speed is 150 mm/s or higher.
The load to mass of the linear servo motor primary-side ratio is 100 times or
less.
The acceleration/deceleration thrust is 10% or less of the continuous thrust.
(3) Machine analyzer function
POINT
Make sure to perform the machine analyzer function after the magnetic pole
detection. If the magnetic pole detection is not performed, the machine analyze
function may not operate properly.
The stop position at the completion of the machine analyzer function can be any
position.
