ence Type
(XREFTYPE) Set the type of data for OLC012 Position Reference
Setting when an OWC020: Motion Command
Code is used in Position Control Mode.
0: Absolute position method
Sets the absolute position at OLC012.
1: Add difference method
Adds the current movement value to the previous
value at OLC012 and then sets that data at
OLC012.
Note: This is an absolute position mode if the posi-
tion reference selection is indirectly speci-
fied.
Refer to 11.3.1 Prerequisites for Position Control.
If using a motion program, be sure to set to 1: Add
difference method.

15 Zero Point
Return Decelera-
tion Point Limit
Signal (LSDEC) This signal functions as a limit switch signal
(deceleration LS) when returning to the zero point.
It is valid when bit 2: Limit Switch Signal Selec-
tion is OFF at fixed parameter number 14: Addi-
tional 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 OBC001F. 0
3 Positive Torque
Limit Setting
(TLIMP) OWC002 -32768 to 32767 This parameter is used to set torque limit refer-
enced by the SERVOPACK and inverter.
• Unit: 0.01%

(-300.00%)
4 Not used. OWC003 Set to “0.” 0
5 Positive Speed
Limiter Setting
(NLIMP) OWC004 0 to 32767 Set the speed limiter value for the positive and neg-
ative directions as a percentage of the rated speed.
The limiter speed will be output if the compensa-
tion speeds added to the specified speed exceeds
this limiter value. 150.00
