Function
description
You can control the speed while applying the acceleration/
deceleration to the velocity commands in the driver, at velocity
control mode.
You can obtain soft-start/soft-down action of the motor when the
phased velocity command is entered, or when the internal veloc-
ity set-up is selected.
<Notes>
Don't use these parameters if the driver is used in combination
with the external position loop. (Both Pr58 and Pr59 should be
set to 0).
You can add a quasi S-shaped acceleration/deceleration to the
velocity command, so that smooth operation can be obtained in
such a case as a large impact shock will be given at starting or
stopping with a linear acceleration/deceleration.
You can set-up the relationship between the motor torque and
the voltage applied to the torque command input (TRQR: CN I/F
pin 14).

1Set the basic acceleration/deceleration
time for the linear regions with Pr58 and
Pr59.
2Set the time of the S-shaped portion, cen
tering the acceleration/deceleration
changing regions with Pr5A. Unit in 2 ms.
