2. Feature Summary
Protocol
Profibus DP (Decentralized Periphery) as specified in European standard EN
50170. The PBDP-110 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.
Drive Connections
The PBDP-110 provides support for simultaneous connection of two Toshiba
7-series, 9-series, 11-series or VF-nC1 ASDs via the drives’ common serial
(aka logic level) communication ports. Both drives share a common Profibus
station address. By supporting 2 drives per interface, the maximum number of
drives that can be connected to 1 Profibus network segment without requiring
repeaters increases from 31 (31 drives + 1 master) to 62 (31 PBDP-110 units +
1 master).
Power Supply
Self-contained. Powered directly from the drive connected to the Channel A
communications port. No external power supply devices or connections are
required.
Isolation
The PBDP-110 has 3 separate isolated circuitry sections. Each drive is fully
optically isolated from each other, and both drives are optically isolated from
the Profibus network. By using optically isolated connections to the drives and
the Profibus network, grounding differential problems are eliminated and noise
immunity characteristics are greatly improved.
Global Control Functions
• Freeze mode: Input (monitor) data values are held constant within the
PBDP-110 until the next “freeze” command or an
“unfreeze” command is received. Used primarily for
synchronized monitoring of multiple Profibus nodes.
• Sync mode
: Output (control) data values are held constant within the
PBDP-110 until the next “sync” command or an “unsync”
command is received. Used primarily for synchronized
control of multiple Profibus nodes.
• Clear_Data
: All output (control) data values are cleared to “0”.
Drive AutoScan Algorithm
Connections to the drives are automatically established and continuously
monitored. No drive configuration needs to be performed to connect the
