(5) Supplemental Information on SCC Command
(a) Related Motion Parameters
SCC command changes the S-curve time constant of the following motion setting parameter.
The S-curve time constant can be changed by directly changing the motion setting parameter OW
3A
(filter time constant) instead of executing an SCC command. Refer to the following table for information on
how to directly change the S-curve time constant.
Motion and setting procedure of S-curve time constant are as follows.
* The built-in SVB and SVB-01 modules can automatically write the setting of motion setting parameter
OW
3A into Average Movement Filter Time Constant of the SERVOPACK parameter.
When this automatic writing function is enabled, you do not need to execute 12 of motion setting parameter
OW
08.
For the automatic writing function, refer to
11.6 Parameters That Are Automatically Updated in Machine Controller
MP2000 Series Built-in SVB/SVB-01 Motion Module User’s Manual (manual number: SIEPC88070033).

Description
Filter time constant
OW
3A
Sets the acceleration/deceleration filter time constant (1 = 0.1 ms).
• Change the filter time constant after confirming that bit 0 of motion moni-
toring parameter IW
0C is set to 1 (discharging completed).
• Change the filter time constant after selecting a filter type using bits 8 to B
of motion setting parameter OW
03 (Filter type selection).

Setting Procedure
SVA-01,
PO-01,
SVR
When S-curve acceleration/deceleration is
enabled, the axis moves according to the
S-curve time constant set in motion set-
ting parameter OW
3A (Filter time
constant).
Set the S-curve time constant to motion setting parameter
OW
3A (filter time constant).
SVB-01,
Built-in SVB
When the S-curve acceleration/decelera-
tion is enabled, the axis moves according
to the Average Movement Filter Time
Constant of the SERVOPACK parameter.
Set the S-curve time constant using the motion setting parame-
ter OW
3A (filter time constant). Then, execute 12 (change
filter time constant) of motion setting parameter OW
08
(Motion command) to write the set S-curve time constant into
the SERVOPACK.
