A JEPMC-REP2000 Repeater must be used if 17 or more slave stations are connected when
using MECHATROLINK-II communication.
3.3.2 SVA-01 Module
( 1 ) Overview and Features
The SVA-01 Module is a motion control module with analog outputs. Each Module can control
Servos or Inverters for up to 2 axes.
The Module has two connectors (CN1 and CN2) for connecting SERVOPACKs and external I/
O. Each connector provides analog outputs for speed references and torque references, analog
inputs for feedback speed monitoring and torque monitoring, pulse input phases A, B, and C (5-
V differential), and general-purpose digital I/O.
The control cycle is fixed at 500 µs, enabling high-precision control without being affected by
the high-speed scan cycle.

Features
＞
• Two analog outputs for Servos for 2 axes
• Position control, speed reference outputs, torque reference outputs, or phase control can be
performed independently for each axis.
