4.4 MP2000 Series Machine Controller Parameter Details
4.4.2 Motion Setting Parameter Details
4-52
( 24 ) Filter
There are two types of acceleration/deceleration filter: an exponential acceleration/deceleration filter and a moving
average filter.
For details on each acceleration/deceleration parameter, refer to 5.1.6 Acceleration/Deceleration Settings and 5.1.7
Acceleration/Deceleration Filter Settings.
( 25 ) Zero Point Return
OW 3A
Filter Time Constant
Setting Range Setting Unit Default Value
0 to 65535 0.1 ms 0
Description
Set the acceleration/deceleration filter time constant.
Always make sure that pulse distribution has been completed (i.e., that monitoring parameter IW 0C, bit 0 is ON)
before changing the time constant.
The actual machine operation depends on the settings in the SERVOPACK parameters. Refer to 11.6 Parameters That Are
Automatically Updated for information on user constants self-writing function.
The setting range is limited by the specifications of the SERVOPACK being used.
When using SGD-N, SGDB-N, SGDH+NS100/115, or SGDS SERVOPACK, the setting range is
between 0 and 5100.
Change the time constant for the filter set using the motion command Change Filter Type.
After setting the filter type to be used, change the time constant.
The overall flow for setting the filter time constant is as follows:
1. Select the filter type in Function Setting 1 (setting parameter OW 03, bits 8 to B).
↓
2. Execute the motion command Change Filter Type.
↓
3. Set the Filter Time Constant (setting parameter OW 3A).
↓
4. Execute the motion command Change Filter Time Constant.
Once the filter type is set using the motion command, the setting is held until the power is turned OFF or the filter type is
changed.
OW 3B ( only)
Bias Speed for Exponential Acceleration/Deceleration
Filter
Setting Range Setting Unit Default Value
0 to 32767
Speed Unit Selection (setting
parameter OW 03, bits 0 to 3)
0
Description
Set the bias speed for the exponential acceleration/deceleration filter.
The setting unit for this parameter depends on the Speed Unit Selection (OW 03, bits 0 to 3), but
the result of applying the speed unit setting is not shown here.
R Position Phase
Speed Torque
R
OW 3C
Zero Point Return Method
Setting Range Setting Unit Default Value
0 to 19 − 0
Description
Set the operation method when the Zero Point Return (ZRET) motion command is executed.
With an incremental encoder, there are 13 different methods that can be performed for the Zero Point Return operation.
Refer to 6.2.3 Zero Point Return (ZRET) for information on each method.
With an absolute encoder, the axis is returned to the zero point of the machine coordinate system regardless of which
method is being used.
OW 3D
Width of Starting Point Position Output
Setting Range Setting Unit Default Value
0 to 65535 Reference unit 100
Description Set the width in which the Zero Point Position bit (monitoring parameter IW 0C, bit 4) will be ON.
OL 3E
Approach Speed
Setting Range Setting Unit Default Value
−2 31 to 2 31 −1
Depends on
Speed Units.
1000
Description
Set the approach speed for a zero point return operation after the deceleration LS is passed.
The setting unit for this parameter depends on the Speed Unit Selection (OW 03, bits 0 to 3), but
the result of applying the speed unit setting is not shown here.
