Acceleration and Deceleration

Unit of Acceleration and Deceleration Rates
Acceleration rates and deceleration rates are given in command units/s
value obtained from unit conversion of the position display unit and the electronic gear.

Function
Set the maximum acceleration rate for an axis
operation command. There will be no limit to
the acceleration rate if 0 is set.
2
(Unit: command units/s )
Set the maximum deceleration rate for an axis
operation command. There will be no limit to
the deceleration rate if 0 is set.
2
(Unit: command units/s )
Set the operation for when the maximum accel-
eration/deceleration rate would be exceeded
after excessive acceleration/deceleration
during acceleration/deceleration control of the
axis because stopping at the target position is
given priority.
0: Use rapid acceleration/deceleration. (Blend-
ing is changed to Buffered.)
1: Use rapid acceleration/deceleration.
*2
2: Minor fault stop
Set the percentage of the maximum accelera-
tion rate at which to output an acceleration
warning for the axis. No acceleration warning is
output if 0 is set.
(Unit: %)
Set the percentage of the maximum decelera-
tion rate at which to output a deceleration warn-
ing for the axis. No deceleration warning is
output if 0 is set.

Meaning
This is the current value of the command
velocity. A plus sign is added during
travel in the positive direction, and a
minus sign is added during travel in the
negative direction.
This is the actual current velocity. A plus
sign is added during travel in the positive
direction, and a minus sign is added
during travel in the negative direction.
