3: SERVOPACK Transmission Reference Mode
SERVOPACK Transmission Reference Mode is used to directly control the command-response
communications with the slave SERVOPACK from an application.
Setting Precautions
• No processing other than communications processing with the SERVOPACK is performed in
this mode. Position control and other processing must be performed in the application.
• Commands to the SERVOPACK are set in the area starting with the OW68 setting
parameter and responses are reported in the area starting with the IW68 monitor
parameter.
Function Selection Flags 1
 Function Selection Flags 1
 Bit 0: Axis Selection
Set whether there is a limit on the movement of the controlled axis.
0: Finite-length axis (default).
This setting specifies a finite-length axis. Software limits can be used.
1: Infinite-length axis.
This setting specifies an infinite-length axis. Software limits cannot be used.
If an infinite-length axis is set, the position information is reset each time the position exceeds
the value that is set for fixed parameter No. 10 (Infinite-length Axis Reset Position).
Setting Precautions
Always set this parameter to 0 for linear motors.

Bit 1: Enable Positive Software Limit
Enable or disable the software limit in the forward direction.
0: Disabled (default).
1: Enabled.
Setting Precautions
• This setting is ignored if the axis is set as an infinite-length axis.
• Set the software limit in fixed parameter No. 12 (Positive Software Limit).
• The software limit is valid only after bit 5 (Zero Point Return/Setting Completed) in the
IW0C monitor parameter changes to 1 (Completed).
Refer to the following section for details on the software limits.
6.3 Software Limits on page 6-9
 Bit 2: Enable Negative Software Limit
Enable or disable the software limit in the reverse direction.
0: Disabled (default).
1: Enabled.
Setting Precautions
• This setting is ignored if the axis is set as an infinite-length axis.
• Set the software limit in fixed parameter No. 14 (Negative Software Limit).
• The software limit is valid only after bit 5 (Zero Point Return/Setting Completed) in the
IW0C monitor parameter changes to 1 (Completed).
