3.4 Motion Parameter Details
3.4.2 Setting Parameter Details
3-58
• The actual machine operation follows the settings in the SERVOPACK parameters. Refer to
the following section for details on automatically applying settings to the SERVOPACK
parameters.
3.5 Automatically Updated Parameters on page 3-86
• The setting range is limited by the specifications of the SERVOPACK.
• This parameter is used as the filter time constant for CHG_FILTER (Change Filter Type)
motion command (depending on the motion command settings).
• Set the filter type first before you change the time constant.
 Procedure for Setting the Filter Time Constant
1. Select the filter type in bits 8 to B in the OW03 setting parameter.
2. Execute the CHG_FILTER command.
3. Use the OW3A setting parameter to set the filter time constant.
4. Execute the SCC (Change Filter Time Constant) command.
 Bias Speed for Indexed Deceleration/Acceleration Filter
Set the bias speed for the indexed deceleration/acceleration filter.
Setting Precautions
The unit that is set in the Speed Unit Selection bits (OW03 bits 0 to 3) is used for this
parameter.
Origin Return
 Zero Point Return Method
Set the operation method when the ZRET (Zero Point Return) motion command is executed.
Setting Precautions
• With an incremental encoder, there are 13 different methods that you can use for the origin
return operation. Refer to the following section for details on these operation methods.
ZRET (Zero Point Return) on page 4-20
• With an absolute encoder, the axis is returned to the origin of the machine coordinate system
regardless of which method is used.
• After you set the filter type with the motion command, the setting is held until the power
supply is turned OFF or the filter type is changed again.
• There are two types of acceleration/deceleration filters: an exponential acceleration/decel-
eration filter and a moving average filter.
• Refer to the following sections for details on acceleration and deceleration parameters.
