PA12 / PA13:
=
( co mmand value mm)*( the nu mb er of wires of the encoder) *(4 quadruple
frequency)/ (pitch)*(the number of pulses)
= 10 *2 500 *4 / 6 *1 0000
=
5 / 3
viz. PA 12 = 5 , PA 13 = 3 .
b. There is a reducer between the servo motor and the lead screw (The lead screw rotates for 2 revolutions
when the motor for 5 revolutions).
●
If the numerical control system programming is 10 mm, then sent out 10000 pulse
●
The photoelectric encoder has 2500 wires.
●
The pitch of the lead screw is 6mm.
PA12 / PA13:
=
( c o m m a n d v a l u e m m ) *( t h e n u m b e r o f w i r e s o f t h e e n c o d e r ) *(4 quadruple
frequency)*(the revolution number of the motor)/ (pitch)*(the number of pulses)* (the revolution
number of the lead screw)
= 10 *2 500 *4 *5 / 6 *1 0000 *2
= 2
5/ 6
Vi z. PA 12 = 25 , PA 13 =6 .
