Parameters for Motion Control
 Negative Software Limit
Set the position to detect the software limit in the reverse direction for the MP3000.
Setting Precautions
• If an axis attempts to move in the reverse direction past this position, a negative software limit
alarm occurs and bit 4 in the IL04 monitor parameter changes to 1.
• This parameter is valid when bit 2 (Enable Negative Software Limit) in fixed parameter No. 1 is
set to 1 (Enabled).
• The software limit is enabled 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.

SERVOPACK Settings
 Motor Type Selection
Select the motor type to use.
0: Rotary motor
1: Linear motor
 Encoder Selection
Set the encoder type to use.
0: Incremental encoder.
1: Absolute encoder.

Setting Precautions
For linear motors, set the encoder type that matches the linear scale and SERVOPACK set-
tings.
