(4) In case of minus move (down) and deceleration
Because torque of Gravity works against the output torque of motor and
torque of friction works forward to the output torque of motor, torque for
acceleration/deceleration is as follows.
Maximum torque : 90(=100–20+10) (Nm)
Speed: 0 to 2000 (min
–1
)
Torque at rapid traverse : 69(=79–20+10) (Nm)
Speed: 3000 (min
–1
)
Minimum torque : 48(=58–20+10) (Nm)
Speed: 4000 (min
–1
)

At P0, 90(Nm) can be used for
the acceleration/deceleration, so
set the ratio 7717 (mm/sec
2
) to
4124 (mm/sec
2
). 1.8712 =
7717/4124
Accel-
eration at
P1
19564 18712 0.01

At P1, 90(Nm) can be used for
the acceleration/deceleration, so
set the ratio 7717 (mm/sec
2
) to
4124 (mm/sec
2
). 1.8712 =
7717/4124

0 is set because P2 to P4 are
skipped.

At P5, 69(Nm) can be used for
the acceleration/deceleration, so
set the ratio 5916 (mm/sec

) to
4124 (mm/sec

). 1.4345 =
5916/4124
