(3) In case of minus move (down) and acceleration
Because torque of Gravity works forward to the output torque of motor and
torque of friction works against the output torque of motor, torque for
acceleration/deceleration is as follows.
Maximum torque : 110(=100+20-10) (Nm) Speed: 0 to
2000 (min
-1
)
Torque at rapid traverse : 89(=79+20-10) (Nm) Speed: 3000 (min

)
Minimum torque : 68(=58+20-10) (Nm) Speed: 4000

At P0, 110(Nm) can be used for the
acceleration/deceleration, so set the
ratio 9431 (mm/sec
2
) to 4124
(mm/sec
2
). 2.2869 = 9431/4124

At P1, 110(Nm) can be used for the
acceleration/deceleration, so set the
ratio 9431 (mm/sec
2
) to 4124
(mm/sec
