SEW-EURODRIVE MOVITRAC 31 FRS 31 Synchronous Operation Control Manual

About this manual

This manual covers the FRS 31 Synchronous Operation Control package, which enables a group of asynchronous motors to maintain angular synchronism. It details the function's eight modes, including free-running, restricted free-running, and synchronous operation with angular offsets. The document explains the principle of continuous angular position comparison between master and slave motors fitted with encoders.

Frequently asked questions

What is the primary function of the FRS 31 Synchronous Operation Control?

It enables a group of asynchronous motors to maintain angular synchronism with one another or at a specified proportional ratio.

What hardware requirement must the slave drive have for synchronous operation?

The slave drive must be fitted with a braking resistor to allow synchronous operation of the master and slave.

How many slaves can be connected to one master in a group configuration?

Up to 10 slaves can be connected to one master for applications like multi-column hoists or travel drives.
