3.4 Motion Parameter Details
3.4.2 Setting Parameter Details
Absolute Infinite-length Position Management Information
 Power OFF Encoder Position (Lower 2 Words) and Power OFF Encoder
Position (Upper 2 Words)
These parameters store information for infinite-length position management when an absolute
encoder is used. The encoder position is stored in 4 words.
When bit 7 (Absolute Infinite-length Position Information Load Request) in the OW00 set-
ting parameter is set to 1 (Request ON), the position information is recalculated based on the
set value of this parameter and the OL62 and OL64 setting parameters (Power
OFF Pulse Position).

OL5E
OL60
Setting Precautions
Set this parameter to 0 for linear motors.
 Power OFF Pulse Position (Lower 2 Words) and
Power OFF Pulse Position (Upper 2 Words)
These parameters store information for infinite-length position management when an absolute
encoder is used.
The axis pulse position that is managed internally by the MP3000 is stored in 4 words.
When bit 7 (Absolute Infinite-length Position Information Load Request) in the OW00 set-
ting parameter is set to 1 (Request ON), the position information is recalculated based on the
set value of this parameter and the OL5E and OL60 setting parameters (Power
OFF Encoder Position).

Setting Precautions
Set this parameter to 0 for linear motors.
Software Limits
 Positive Software Limit
Set the position to detect the software limit in the forward direction for the MP3000.

OL66 Positive Software Limit
Setting Precautions
• This parameter is valid when bit 1 (Enable Positive Software Limit) in fixed parameter No. 1 is
set to 1 (Enabled) and bit C (Software Limit Parameter Selection) is set to 1 (Setting parame-
ter).
