Page 9: Feature Summary
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). - Page 10 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”...
- Page 11 In addition to the above signals, the metallic housing of the DB9 connector is connected to the shield section of the interface board. The shield section is attached to the metal ground terminal on the bottom of the unit, where a ground wire can be attached to connect the Profibus network cable shield to ground.

Page 13: Installing The Interface
3. Installing The Interface The PBDP-110 connects to each drive via the drive’s common serial (logic level) communication port, typically located on either the main drive control board (G7), on the front of the drive enclosure under a small snap-on cover (A7, S9), or on the right- hand side of the drive enclosure under a small snap-on cover (S7). -

CNU2A (on the EOI), then this connection must first be switched over to CNU1 (on the drive control board) and CNU1A (on the EOI). Refer to Toshiba’s documentation for any precautions or notices regarding this connection change. If the EOI is already connected via the RS485/RS232 channel, then no change is required. - Page 15 power to the drive has been removed. A hazard exists temporarily for electrical shock even if the source power has been removed. Verify that the CHARGE LED has gone out before continuing the installation process. 3. Attach the mounting clip and unit enclosure in your desired manner (refer to page 10 for more information).

Page 16: Grounding
4. Grounding Grounding is of particular importance for reliable, stable operation. Communication system characteristics may vary from system to system, depending on the system environment and grounding method used. The PBDP-110 Profibus interface is provided with a “Shield GND” terminal on the bottom of the unit. The “Shield GND” terminal is directly connected to the metallic housing of the DB9 connector, which should in turn be connected to the shield of the Profibus network cable through the Profibus connector. -
Page 17: Maintenance And Inspection
6. Maintenance And Inspection Preventive maintenance and inspection is required to maintain the communication interface in its optimal condition, and to ensure a long operational lifetime. Depending on usage and operating conditions, perform a periodic inspection once every three to six months. Before starting inspections, always turn off all power supplies to connected drives, and wait at least five minutes after each drive’s “CHARGE”... -
Page 18: Storage And Warranty
7. Storage And Warranty 7.1 Storage Observe the following points when the communication interface is not used immediately after purchase or when it is not used for an extended period of time. Avoid storing the unit in places that are hot or humid, or that contain large quantities of dust or metallic dust. -
Page 19: Selecting The Profibus Network Address
8. Selecting the Profibus Network Address The 8-position piano-style “Address” DIP switches accessible from the front of the unit allow selection of the Profibus slave address. Switch positions #1 #7 select the address. Switch position #8 is reserved for production test use, and should always be kept in the “OFF”... - Page 20 (continued…) Addr Addr Note that the “ON” position of each switch is the “down” position and that the “OFF” position is the “up” position. Refer to the indicator markings on the switch. The address switch settings are read by the interface only on power-up. Therefore, if the address is changed, be sure to power the PBDP-110 off momentarily by cycling power to the drive connected to “Channel A”...

Page 21: Exchanged Data Structures
9. Exchanged Data Structures 9.1 Output (Control) Data Format The size of the output data structure from the network master to the PBDP-110 depends on the module selected from the GSD file for the network configuration tool. Module #1, intended for applications where only 1 drive is connected to the PBDP- 110 (via Channel A), is comprised of 16 bytes structured as four 32-bit words. - Page 22 Command Word Bit-mapped drive control command word (drive parameter number FA00). This is the location where run/stop, etc. commands are written. An example command word can be found in Table 1. Because the format of this command word depends on the drive manufacturer’s specifications, please refer to your specific drive’s Serial Communications Manual for the exact structure of this word.
- Page 23 Frequency Command Drive parameter number FA01. The data contained in the frequency command word is the desired frequency command multiplied by 100, and then converted to hexadecimal. In other words, if a frequency command of 55.34Hz is desired, then 55.34 x 100 = 5534, which converted to hexadecimal is 0x159E. The frequency command high byte (offset 6 or 22) must therefore contain 0x15, and the frequency command low byte (offset 7 or 23) must contain 0x9E.
-
Page 24: Input (Status) Data Format
9.2 Input (Status) Data Format The size of the input data structure from the PBDP-110 to the network master depends on the module selected from the GSD file for the network configuration tool. Module #1, intended for applications where only 1 drive is connected to the PBDP- 110 (via Channel A), is comprised of 24 bytes structured as six 32-bit words. - Page 25 Locations marked “Reserved” in the above table are reserved for future use. Presently, all “Reserved” input data is set to 0 by the PBDP-110. Future firmware releases, however, may use these locations for data transfer. The format of all information transferred for Drive B is identical to that for Drive A. Therefore, all data descriptions given here apply equally for both Drives A and B.
- Page 26 Output Frequency Drive parameter number FD00. Continuously reports the drive’s operating frequency. In order to determine the drive’s actual output frequency, the data contained in the output frequency word offsets must first be converted from hexadecimal to decimal, and then divided by 100. For example, if the output frequency high byte is 0x12 and the output frequency low byte is 0x34, then 0x1234 converted to decimal is 4660.

Page 30: Parameter Access Procedure
10.3 Parameter Access Procedure In order to read from a parameter or write to a parameter, 2 control bits are provided for each drive’s data structure. These bits, labeled Req1 and Req0 in the Action Bits word, can have the following values: Req1 Req0 Meaning... -
Page 31: Register Access Error Codes
If the request was a write, and the write was performed successfully, this will be indicated to the master by Resp1:Resp0 changing from 0:0 to 1:0. The parameter number response will equal the accessed parameter number, and the data written to the drive will be reflected in the data / error code response word. -
