Reference Unit
The
Σ
-V-SD driver uses MECHATROLINK-III communications to send commands to and receive feedback
data from the host controller.
The SERVOPACK performs servo control in pulse units (i.e., at the encoder resolution), so commands from
the host controller are also in pulses.
Encoder Resolution
The encoder resolution depends on the motor.
SGMGV- 8
20-bit absolute value: Resolution = 1,048,576
UAK J- Z
12-bit incremental value: Resolution = 4,096
