( 6 ) Conditions when the Power Supply Must Be Turned OFF and ON
When any of the following operations is performed, save the settings to flash memory and then turn
the power supply OFF and ON.
• After executing a self-configuration command from the MPE720 after turning ON the power
supply
• After loading a Module definition after turning ON the power supply
• After changing the SVB communication cycle in the CPU after turning ON the power supply
• After operation changes from synchronized to asynchronized or from asynchronized to
synchronized when the high-speed scan setting is changed
1.3 SVA-01 Module Overview and Features
1.3.1 Overview
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
µ
s, enabling high-precision control without being affected by the
high-speed scan cycle.
