(cont’d) Bit 14 Speed Reference
Type
(XREFTYPE) Set the type of data for OL††12 Position Reference Set-
ting when an OW††20: Motion Command Code is used
in Position Control Mode.
0: Absolute position method
Sets the absolute position at OL††12.
1: Incremental addition method
Adds the current movement value to the previous
value at OL††12 and then sets that data at
OL††12.
Note: Only the absolute position method can be set if
the position reference selection is indirectly
specified.
Refer to Position Reference of 2.3.1 Prerequisites for
Position Control.

Bit 15 Zero Point
Return Decelera-
tion Point Limit
Signal (LSDEC) This bit functions as a limit switch signal (deceleration
LS) when returning to the zero point. It is valid when bit
2: Limit Switch Signal Selection is OFF at fixed parame-
ter number 14: Additional Function Selections. The
external signal (DI signal input by the LIO-01 or other
Module) in the user program must be connected (i.e., pro-
grammed) to OB††01F. 0
3 Positive
Torque Limit
Setting
(TLIMP) OW††02 -32768 to 32767 Valid only for SVA-02A (2-axis) Module.
Used to set torque limit referenced by the SERVOPACK
and inverter.
Unit: 0.01%
Set a positive value (0.01% units) with a VS-866 and a
negative value (0.01% units) with a SERVOPACK. -300.00
(-300.00
%)
4 Not used. OW††03 − Set to “0.” 0
5 Positive Speed
Limiter Setting
(NLIMP) OW††04 0 to 32767 Set the speed limiter value for the positive and negative
directions as a percentage of the rated speed. The limiter
speed will be output if the compensation speeds added to
the specified speed exceeds this limiter value. 150.00
