2. Feature Summary
The PBDP-110 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
PBDP-110 which allow for this control and configurability are briefly described here:
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 7-series or 9-
series Toshiba drives. 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.
Drive AutoScan Algorithm
Connections to the drives are automatically established and continuously monitored.
No drive configuration needs to be performed to connect the PBDP-110 and
communicate via the Profibus network. Just plug it in – it’s that simple.
