Note: These are parameters for Σ-7-Series SERVOPACKs. Refer to the manual for your SERVOPACK for details on param-
eters for SERVOPACKs in other series.
Precautions for Parameter Settings
The names of some of the motion parameters and SERVOPACK parameters are different even
though they have the same meaning. Set the values of these motion parameters and SERVO-
PACK parameters so that they are consistent with each other. The following tables list informa-
tion on the settings.
Encoder Selection
Set the parameters as listed in the following table for an axis that performs absolute position
detection.

The setting of the Pn212 (Number of Encoder Pulses) SERVOPACK parameter is not used for
control with the MP3000. It is not necessary to change the setting of Pn212.
5.2.6 Position Management Method for Each Machine Operation Type
Description
0: Use CCW as the forward direction. (Rotary
Servomotor)
Use the direction in which the linear encoder
counts up as the forward direction. (Linear Ser-
vomotor)
1: Use CW as the forward direction. (Rotary Ser-
vomotor)
Use the direction in which the linear encoder
counts down as the forward direction. (Linear
Servomotor)
0 to 65,535
0: Use the encoder according to encoder specifi-
cations.
2: Use the encoder as a single-turn absolute
encoder.
Parameter
1: Absolute encoder
X
0: Use the encoder according to encoder specifications.
2: Use the encoder as a single-turn absolute encoder.
