New EtherCAT Drive from Galil Motion Control

ROCKLIN, Calif. — The EDD-3701x EtherCAT slave drive joins Galil’s EtherCAT Family.  This family has grown to include two EtherCAT masters and an I/O slave with both digital and analog I/O points.  The EDD-3701x is a motor amplifier that operates in an EtherCAT distributed system where there are up to 32 slave drives and one master. It has a daisy chain topology using standard CAT5 Ethernet cables.  The EDD-3701x can interface with Galil masters (DMC-500x0 and DMC-52xx0) for sophisticated applications or with TwinCAT® for very simple applications.

The EDD-3701x series has the ability to control brushed, brushless, steppers, and microstepping motors (See Table 1 for more details).  Unlike the competition, the EDD-3701x can both control a motor and also has 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs. All I/O information from these drives are accessible by the EtherCAT master.  This capability can eliminate the need for separate EtherCAT I/O devices.  The configuration of the EDD-3701x is done using the Galil’s GDK software.  Simply connect to a PC via EDD-3701x’s USB port, follow the GDK configuration tool process, and start moving motors.  The EDD-3701x also comes with a setup guide to get the user from taking the EDD out of the box to moving motors in a manner of minutes.
