1. Introduction
Congratulations on the purchase of the new G7 Adjustable Speed Drive (ASD) Multi-Protocol 
Communication (ASD-MULTICOM-A) or PG Feedback (ASD-MULTICOM-B) Option. 
 
 
 
ASD-MULTICOM-A / ASD-MULTICOM-B 
These option cards provide the ability to connect various different pulse generator/feedback sources, 
such as encoders, to the G7 ASD. These PG input signals can then provide enhanced performance for 
vector control, pulsed speed command, and process (PID) control applications. 
 
Two different types of pulse input circuitry are provided, which allows very flexible application and 
connectivity to a wide array of PG devices available on the market today. 
 
 
 
ASD-MULTICOM-A 
In addition to the PG feedback circuitry, this option card also provides connectivity to the most popular 
fieldbus networks in use today. These networks include Profibus, DeviceNet, and RS-485 based 
networks. Different option board firmware versions may provide varying levels of support for these 
different networks, so when using this manual, always keep in mind that the firmware version operating 
on your option board must match this manual’s respective revision for all documented aspects to apply. 
The option board firmware version covered by each revision of the manual is indicated in the last 
section of the “Document Number” on the manual’s front cover. For example, if the Document Number 
on the front cover ends in “-V3.00”, then this manual is only applicable for version 3.00 option board 
firmware. 
 
The method of determining your board’s firmware version varies depending on the network being used. 
Please refer to the specific network interface sections of this manual to determine the method required 
for your installation. 
 
 
 
This manual will primarily be concerned with the option’s hardware specifications, input characteristics, 
configuration, and installation and wiring precautions. For more advanced application-level 
information, please contact Toshiba’s ASD Marketing Department for copies of available application 
notes. 
 
To maximize the abilities of your new ASD option, a working familiarity with this manual will be 
required. This manual has been prepared for the option installer, user, and maintenance personnel. With 
this in mind, use this manual to develop a system familiarity before attempting to install or operate the 
device.
