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.

4.1 Installation Procedure

The interface cards for the G7 ASD have been designed for quick and simple installation. The card is
connected to the drive's control board via an 80-pin connector, and is mechanically supported with
nylon standoffs attached through the control PCB to the chassis. The only tools required for installation
are a flat screwdriver, a #2 Phillips screwdriver and, for most installations, a utility knife to aid in the
removal of the front cover's side access window. Each interface card kit includes one #51326A
connector PCB and four #47220 nylon hex standoffs.

Before opening the drive, please observe all safety precautions as outlined on the unit's front cover and
in the operation manual. After securing the unit against hazardous voltages, loosen the two lower
fasteners and remove the cover, taking care not to damage the keypad-to-drive cable connection.
Remove the four pan head screws that secure the control PCB to the drive (refer to Figure 1) and replace
with the #47220 1/2" hex standoffs provided. Make these substitutions one or two fasteners at a time to
prevent any shifting of the control board.

Install the #51326A connector PCB in the control board's 80-pin connector, making sure that the
connector is fully seated. Next, position the option card and snap the connectors together. Finally,
secure the card to the standoffs with the remaining pan head screws (see Figure 2).

Figure 2

If your option card is equipped with a data connector along its right side edge, you will need to remove
the side access window of your drive's cover before reinstalling it. Place the cover upside down on a
level surface (see Figure 3), and with downward pressure on your utility knife, cut along the two vertical
grooves. Next, bend the resulting flap back and forth several times until it snaps apart. Clean up the
opening as necessary and reattach the front cover to the drive.

The pulse input signals should have the waveform of the figure below in terms of motor rotation
direction. The encoder installation direction and signal wiring should be done accordingly.
Forward rotation or reverse rotation is determined from the quadrature orientation of the Phase A and
Phase B feedback pulses. Therefore, it should be noted that when connections are wrong, there is a

possibility for abnormal rotation of the motor.

6.5 Maximum Input Frequency Using an Open
Collector Encoder

When using an open collector (pulse input type 2) encoder, the rise time of the voltage when the
encoder’s internal transistor turns OFF tends to be longer than the fall time when the transistor turns
ON. Therefore, if the input frequency becomes high enough, the pulse duty cycle cannot maintain the
50±10% specification. For the pulse duty cycle to be within the specified range, the generated
frequency from the open collector encoder needs to be below a maximum input frequency. To calculate
the maximum input frequency for an open collector (pulse input type 2) encoder, use the following
equations:

(eq.1)

Single phase input: A=2

Two phase input: A=4

This section applies to ASD-MULTICOM-A option boards only.

The interface board contains two bi-color red/green status LEDs. The lower LED indicates the Module
Status (MS), and the upper LED indicates the Network Status (NS). Refer to Figure 2. The use and
context of these LEDs is network-specific: refer to each network’s section in this manual for further
information.

8. Network Configuration Parameters

This section applies to ASD-MULTICOM-A option boards only.

Because the Multicom interface supports several different fieldbus physical layers and protocols, some
configuration must be performed prior to inclusion on the network to inform the Multicom interface
which network it is being asked to communication via, and what the characteristics of that network are.
This configuration is performed by setting ASD parameters F890 ~ F894, which are collectively known
as the “Network Configuration Parameters”.

Note that the values of these 5 Network Configuration Parameters are only read by the Multicom
interface upon initialization after a drive reset or power-up condition

parameters are changed, be sure to reset the drive to enable the changes (as will be explained later, this
may actually involve resetting the drive twice: once when changing the “Network Selection” parameter
to validate the chosen network, and then once more when changing any of the configuration items
associated with the chosen network). Also note that although parameters F890 ~ F894 are always
available, whether or not all of these configuration parameters are actually used by the Multicom
interface will depend on the Multicom interface’s firmware version and the selected network.

The primary network selection is chosen by parameter F890 (refer to Table 4).

. Therefore, if any of these

Table 4: Network Selection

Parameter Function Settings Default Value

F890

The function and adjustment ranges assigned to parameter F890 are fixed; that is to say that parameter
F890 is always the “Network Selection” parameter. The functions and adjustment ranges of the
remaining network configuration parameters (F891 ~ F894), however, will vary based on the setting of
parameter F890. For example, when parameter F890 is configured for Profibus DP communications,
then parameter F891 is unused, and its upper and lower adjustment limits will both be “0”. When
parameter F890 is configured for Modbus RTU communications, however, then parameter F891 is used
to select the Modbus network baud rate, and its adjustment range then becomes 0 ~ 7.

As previously mentioned, the values of the Network Configuration Parameters are validated by the
Multicom interface only during a drive initialization procedure. Therefore, when the drive and the
Multicom interface are initializing, the settings of the Network Configuration Parameters are read and
internally saved by the Multicom interface. These internally-saved values
initialization procedure. For this reason, two drive resets may be required when modifying the Network
Configuration Parameters: one to change and validate the network selection (parameter F890), and
another one to change and validate the remaining Network Configuration Parameters (parameters F891
~ F894) if necessary.

This behavior may best be explained through the use of an example. Say, for instance, that the
Multicom interface is currently configured for Profibus DP communications (parameter F890 = 0).
Let’s also say that we would like to reconfigure the Multicom interface to communicate via Modbus
RTU at 38.4kbaud with even parity, and that all configuration parameters are currently at their factory­default values:

1. Apply power to the drive. The drive and Multicom interface initialize. Parameter F890 is set
to 0, so the Multicom interface internally configures itself for Profibus DP communications.

2. Change parameter F890 from its current setting of “0” to “1” to select Modbus RTU
communications. Press the “ENTER” key on the drive’s panel to write the change. At this
point, the Multicom interface is
parameters F891 ~ F894 will not be adjustable beyond “0”.

3. Reset the drive (fault the drive and reset it, or momentarily power it off). Now, parameter
F890 is set to 1 during initialization, so the Multicom interface internally configures itself for
Modbus RTU communications.

4. Now when we inspect parameter F891 (now “Modbus baud rate”), the value will be 5.
Therefore, we need to change parameter F891 from its current setting of “5” (9600 baud) to
“7” (38.4kbaud). Press the “ENTER” key on the drive’s panel to write the change. At this
point, the internal Modbus baud rate is

5. Similarly, change parameter F892 (now “Modbus parity & stop bits”) from its factory-default
value of “1” (no parity/2 stop bits) to “2” (even parity).

6. Reset the drive once more. Now, when the drive and Multicom interface initialize, the
Multicom interface will initialize with Modbus RTU communications at 38.4kbaud and even
parity. The network configuration is now completed.

Once the network configuration parameters are configured for a specific network, their settings for that
network will be retained even if a different network is chosen and the second network’s configuration
parameters changed. Continuing with the above example for demonstration, even if a different network
is chosen, and parameters F891 ~ F894 associated with that network are changed, and then Modbus
RTU communications are once again selected by changing parameter F890 to “1”, the Modbus baud
rate will still be set to 38.4kbaud, and the parity will still be set to “even” when drive/Multicom
initialization has completed.

9. Profibus Interface

This section applies to ASD-MULTICOM-A option boards only.

9.1 Feature Summary

The Multicom interface provides a wide array of network data access and drive control features.
Combined with the flexible configuration and high-speed data transfer capabilities of the Profibus
network, this allows powerful networked control and monitoring systems to be designed. Some of the
main features provided by the Multicom interface which allow for this control and configurability are
briefly described here:

Protocol

Profibus DP (Decentralized Periphery) as specified in European standard EN 50170. The Multicom
interface can also co-exist simultaneously on networks using Profibus-FMS.

Network Baud Rates

Supports all Profibus baud rates from 9.6kbaud to 12Mbaud. The network baud rate is automatically
detected and continuously monitored during operation; no parameter settings are necessary.

Power Supply

Self-contained. Powered directly from the connected drive. No external power supply devices or
connections are required.

Isolation

The drive is fully optically isolated from the Profibus network. By using optically isolated connections,
grounding differential problems are eliminated and noise immunity characteristics are greatly improved.

Global Control Functions

• Freeze mode:

• Sync mode:

• Clear_Data:

Network Watchdog

Input (monitor) data values are held constant within the Multicom interface until

the next “freeze” command or an “unfreeze” command is received. Used
primarily for synchronized monitoring of multiple Profibus nodes.

Output (control) data values are held constant within the Multicom interface until

the next “sync” command or an “unsync” command is received. Used primarily
for synchronized control of multiple Profibus nodes.

All output (control) data values are cleared to “0”.

A network watchdog function is always operating within the Multicom interface (if selected at time of
unit commissioning). In the event of a disconnection from the Profibus network or loss of the network
master, the Multicom interface will automatically set its control data to 0.
