13.3 Toshiba Common Serial ASD Protocol
•
The gateway can act as a Toshiba ASD master via the dedicated common
serial port connections. All Toshiba ASDs that include a common serial
port are supported.

No configuration is necessary, as the gateway automatically adapts to the
ASD’s configured characteristics.

All parameter writes use the drive’s RAM / EEPROM data write (“W”)
command. For all writes that target the drive’s EEPROM, be sure to follow
Toshiba’s guidelines regarding the number of times a specific parameter
can be written without risk of EEPROM damage.

13.4 Toshiba RS485 ASD Protocol
•
The gateway can act as a Toshiba ASD master via its RS485 ports. All
Toshiba drives that implement the Toshiba protocol and provide either a
built-in or option-based RS485 port are supported.

built-in or option-based RS485 port are supported.
•
Because the gateway implements a 2-wire (half-duplex) RS485 network,
the drive(s) involved must also be connected via 2-wire mode. Optionally,
it is also possible to convert the gateway’s network from 2-wire (half-
duplex) to 4-wire (half-duplex) via an external repeater such as the
485OPIN from B&B Electronics (http://www.bb-elec.com).

Note that Toshiba 7-series drives configured for 2-wire mode (F821=0)
shipped prior to early 2006 may exhibit an issue that can cause their
RS485 ports to stop communicating after a certain amount of time. Please
contact Toshiba technical support to confirm your configuration prior to
using 2-wire RS485 mode on these drives.

The required drive configuration will vary depending on the specific drive(s)
involved. In general, most parameters are freely configurable to match the
gateway’s port settings (baud rate, parity etc.) The most critical selection,
however, is that if the drive is directly connected to the gateway via 2-wire
mode, then the drive must be properly configured for 2-wire RS485. Note
that this may involve hardware configuration in addition to parameter
changes. For example, G7/Q7/H7-series drives have duplex selection
jumpers located on the drive’s control board near the communication ports.
For these drives, both jumpers must be placed in the “HALF” position.
Refer to Figure 26 for an example detailed view of correctly-positioned
duplex selection jumpers.
