The SI-B3/V option connects a V1000 drive to a BACnet network and facilitates the exchange
of data.
This manual explains the handling, installation and specifications of this product.
The SI-B3/V option is a simple, networking solution that reduces the cost and time to wire
and install building automation devices, while providing interchangeability of like
components from multiple vendors.
Drives can be monitored and controlled by a controller on a Building Automation and Control
network (BACnet) using RS-485 technology and MS/TP (Master-Slave/Token-Passing)
protocol. The drives conform to the BACnet application specific controller (B-ASC) device
profile.
Up to 127 drives can communicate on a single BACnet MS/TP network. If more drives or
BACnet devices are required, then a BACnet router is required to allow another MS/TP
network to be available with up to another 127 drives.

Figure 18 Connection Diagram for Multiple Connections
Figure 19 Connecting Multiple Drives to a BACnet Workstation – System Overview
The two ends of the BACnet network must be terminated with a 120 ohm resistor
between the “+” and “-” and signals. The SI-B3 has a built in termination resistor that
can be enabled or disabled using DIP switch S1. If a drive is located at the end of a
network line, enable the termination resistor by setting DIP switch S1 to the ON
position. Disable the termination resistor on all slaves that are not located at the end
of the network line by setting DIP switch S1 to the OFF position (The factory setting
for DIP switch S1 is OFF).

5 Installation Procedure
u
BACnet Node Addressing
The BACnet node address is configurable by parameter F6-45 in the drive. This defines the
physical address of the drive on the MS/TP network. In addition, both the Device Object
Instance Identifier (parameters F6-48 and F6-49) and the Device Object Name are
configurable. These allow the drive to have a virtual address and simplify the controller
configuration.
After setting the addressing, a controller can initiate communication to the drive. The drive
will perform the specified function and then send a response back to the controller. The drive
will usually respond immediately, but may delay its response until it gets the token for
commands that may take extra local processing time.
For easy network implementation of drives equipped with the SI-B3/V option, an EPIC file
can be obtained from:
U.S.: http://www.yaskawa.com
Other areas: Contact a Yaskawa representative.
Refer to BACnet Protocol Implementation Conformance Statement (PICS) on page 45
The following parameters are used to set up the drive for operation with the option. Parameter
setting instructions can be found in the drive Quick Start Guide or Technical Manual.
Confirm proper setting of the all parameters in Table 7 before starting network
communications. After changing parameter settings, cycle power to the drive for the new
settings to take effect.

When an alarm occurs, the ALM LED flashes.
If communication stops while the drive is running, use the following questions as a guide to
help remedy the fault:
• Is the option properly installed?
• Are the communication lines properly connected to the option? Are the wires loose?
• Is the controller program working? Has the controller/PLC CPU stopped?
• Did a momentary power loss interrupt communications?

• Check that power is supplied to the PLC
• Check that PLC is not in program mode
• Check for faulty wiring
• Correct any wiring problems
• Check the various options available to minimize the effects of noise
• Counteract noise in the control circuit, main circuit, and ground wiring
• If a magnetic contactor is identified as a source of noise, install a surge absorber
to the contactor coil
• Make sure the cable used meets requirements
• Make sure the option ground wire is connected between option FE terminal
and the drive ground terminal connected to earth ground
• If available, use IG5 to connect to network common. Refer to Connection

BN_ERR_VALUE_OUT_OF_RANGE
Value written to the parameter is out of the valid range.
BN_ERR_WRITE_ACCESS_DENIED
An invalid parameter register number was used when writing.
Writing to a parameter was attempted while the drive was in a mode that disables writing (i.e.,
writing while the drive was Auto-Tuning).
Writing to a parameter was attempted while the DC Bus had an Undervoltage (Uv) fault.
Parameter F6-14, bUS Fault Auto Reset Select, will appear when the option is installed.
Setting F6-14 = 0 (Disabled) or F6-01 = 3 or greater (Alarm only) will cause the drive to
declare an alarm after the time set in F6-04 has passed.
Setting F6-14 = 1 (Enabled) AND F6-01 ≠ 3 (Fault) will cause the following operation: The
bUS fault occurs after the F7-16 + F6-04 delay time and the Run command is removed from
the drive. Then the option throws a bUS fault to the drive. When the condition is removed,
the option commands a fault reset and returns control of the drive to the BACnet network.
Note:The option will only read parameters F6-01 and F6-14 from the drive during power-up.
bUS Fault Delay
Parameter F7-16, Communications Loss Detection Time Delay, will appear when the option
is installed.
The setting value of F7-16 + F6-04 is the length of time that the option will delay sending the
bUS fault to the drive.
The status LEDs on the option are not affected by the delay time set in F7-16; the LEDs will
indicate the bUS condition immediately.
Note:The option will only read parameters F6-04 and F7-16 from the drive during power-up.
The drive operations that can be performed by BACnet communication depend on drive
parameter settings. This section explains the functions that can be used and related parameter
settings.
u
Observing the Drive Operation
A controller can perform the following actions with BACnet communications at any time
regardless of parameter settings:
• observe drive status and drive control terminal status from a controller
• read and write parameters
• set and reset faults
• set multi-function inputs.
Note:

The Present Value (PV) of BACnet objects can be read. In addition, some PVs can be written
or commanded. A commandable PV is similar to writing the value, but the value is actually
written into a priority array. The value occupying the highest priority in the array will be used
by the drive. The convention for showing how the PV is accessed is shown in Table 10 and
will be noted for the PV of each object.

The Device Object Instance ID is a unique internetwork-wide numerical value. It is a 22-bit
value that can range from 0 to 4,194,303. It is configurable by parameters F6-48 and F6-49.
Any changes to these parameters will not take effect until the power is cycled to the drive.
The Device Object Name is a unique internetwork-wide character string. It is a 20-character
string. It is writable from the BACnet network. Any new string written will not take effect
until the power is cycled to the drive.
10 Accessing Drive Parameters and the Enter Command
u
Enter Command
Enter Commands are only required when using AV29 and AV30 to write drive parameters.
An Enter command is not required when reading or writing to the other BACnet objects.
When writing parameters to the drive from a controller using BACnet communications, an
Enter command must be issued to enable these parameters. This section describes the types
and functions of the Enter commands.
Enter Command Types
n
The drive supports two types of Enter commands as shown in Table 18.
Table 18 Enter Command Types
BACnet ObjectModbus AddressDescription
BV55 (Write “ON”)0910H (bit 0)
BV56 (Write “ON”)0900H (bit 0)
Note:The EEPROM can only be written to 100,000 times, so it is recommended to limit the number of times
writing to the EEPROM. The Enter command registers 0900H and 0910H are write-only and if these
registers are read, the register address will be invalid. However, BACnet objects BV55 and BV56 can
be read without error.
Writes data in the active RAM only. Parameter changes are lost
when the drive is shut off.
Simultaneously writes data into the EEPROM (non-volatile
memory) of the drive and enables the data in active RAM.
Parameter changes remain after cycling power.
Product Description: The Yaskawa SI-B3/V BACnet option connects a V1000 Drive to a
