PT49
STA
Acceleration
time constant
Set an acceleration time taken from 0 r/min or 0 mm/s to the rated speed for the
command. When a value exceeding 2000 ms is set in other than the profile velocity
mode (pv), [AL. F4] will occur and the servo motor cannot be driven.
Profile mode
Set the acceleration time constant in the position mode and
the velocity mode.
Point table method
Set the acceleration time constant in the Jog mode (jg).
Indexer method
Set the acceleration time constant in the indexer mode (idx)
and Jog mode (jg).
If the preset speed command is lower
than the rated speed, acceleration/
deceleration time will be shorter.

(0 mm/s)
For example, for the servo motor with the rated speed of 3000 r/min, set 3000 (3 s)
to increase speed from 0 r/min to 1000 r/min in 1 s.
This parameter corresponds to "Profile acceleration (Index: 6083h)". When this
parameter is mapped for the PDO communication, the value written with Setup
software (MR Configurator2
TM
) is overwritten with the upper side. Thus, do not write
a value with Setup software (MR Configurator2
TM
).
Setting range: 0 to 50000
Set an acceleration time taken from 0 r/min or 0 mm/s to the rated speed for the
command. When a value exceeding 2000 ms is set in other than the profile velocity
mode (pv), [AL. F4] will occur and the servo motor cannot be driven.
Profile mode
Set the acceleration time constant in the position mode and
the velocity mode.
If the preset speed command is lower
than the rated speed, acceleration/
deceleration time will be shorter.

For example, for the servo motor with the rated speed of 3000 r/min, set 3000 (3 s)
to increase speed from 0 r/min to 1000 r/min in 1 s.
This parameter corresponds to "Profile acceleration (Class ID: 64h, Ins ID: 6083h,
Attr ID: 0)". When this parameter is mapped for the I/O communication, the value
written with Setup software (MR Configurator2
TM
) is overwritten with the upper side.
Thus, do not write a value with Setup software (MR Configurator2
