6.8.3 Link Assignments
You can manually assign links as shown below according to the model of the ?-7-series SER-
VOPACK.
An example of the on-screen settings is shown below.
6.8.4 Number of Pulses Per Motor Rotation
Set fixed parameter No. 36 (Number of Pulses per Motor Rotation) according to setting of the
electronic gear ratio as given below.

Electronic Gear Ratio of 16:1 (Equivalent to 20 Bits)
 Electronic Gear Ratio of 1:1 (Equivalent to 24 Bits)
6.8.5 Self Configuration
When you execute self-configuration, the link assignment is set automatically according to the
model of the connected Σ-7-series SERVOPACK.
However, the electronic gear ratio in the SERVOPACK and fixed parameter No. 36 (Number of
Pulses Per Motor Rotation) are automatically set according to the version of the MP3000 as
given below.
