5. PARAMETERS
No./ Setting
symbol/name digit
PT46 Set a primary delay filter time constant to the synchronous encoder command.
Setting this parameter reduces vibration. However, a delay in response to the
ESTC
synchronous encoder will be generated.
Synchronous
A setting value when Synchronous control command (C_STS) is turned on will be
encoder filter
applied to this parameter.
time constant
This parameter setting is available with servo amplifiers with software version B0 or
later.
Setting range: 0 to 5000
PT49 Set an acceleration time taken from 0 r/min or 0 mm/s to the rated speed for the
command.
STA
Acceleration
time constant
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 MR
Configurator2 is overwritten with the controller. Thus, do not write a value with MR
Configurator2.
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.
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 MR Configurator2 is overwritten with the controller. Thus, do not write a
value with MR Configurator2.
Setting range: 0 to 50000
In the profile mode
Set an acceleration time constant for the position mode and velocity mode. Setting
a value exceeding 20000 ms in the position mode will trigger [AL. F4].

Function
If the preset speed command is lower
than the rated speed, acceleration/
