4. DESCRIPTION OF PARAMETERS
B63180EN/02
46
1620
Time constant used for linear acceleration/deceleration or bellshaped accelera-
tion/deceleration in rapid traverse for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 4000
Specify a time constant used for acceleration/deceleration in rapid tra-
verse.
(1) When the function is provided, set this parameter to time constant
T
1
used in bellshaped acceleration/deceleration in rapid traverse,
and set parameter No.1621 to time constant T
2
.
(2) When the function is provided, specify a time constant used in
linear acceleration/deceleration and set parameter No.1621 to 0.

Set the value when the rapid traverse rate is 100%. If it is under 100%, the
total time is reduced. (Constant acceleration method)
The value of T
1
is determined from the torque of motor. Usually set the
value of T
2
to 24 ms or 32 ms.

verse for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 512
Specify time constant T

used for bellshaped acceleration/deceleration
in rapid traverse for each axis.
