Chapter 7
Option
Communication option board DBIF2009-Z and the cover for DB units are prepared for VFDB2009 series
dynamic brake system as an option.
7.1
Communication option board [DBIF2009-Z PC board]
If a communication option PC board is used, communication with VF66 series inverter (the capacity only of
a model of 30kW or more) will be attained, and operation which synchronized with the inverter will be
attained.
※
At the time of single operation of VFDB2002 series dynamic brake system and a parallel operation with
VFDB2002 series dynamic brake system, a communication option substrate is inapplicable.
※
When communicating using a communication option PC board, the number connected to parallel of VFDB2009
series dynamic brake system with the capacity of VF66 series inverter has restriction. The 30 to 55kW model
of VF66 series inverter should carry out the DB unit maximum parallel number to two sets. (The DB unit
maximum parallel number of the 75kW or more model of VF66 series inverter is six sets. )
※
The wiring length of the telecommunication cable from VF66 series inverter to DB unit of a termination should
give as a maximum of 5 [m].
7.1.1 Extension of the function by appling of a communication option PC board
The following functions are added by using communication option PC board DBIF2009-Z.
○
Adjustment of the display gain /offset of D.C. voltage becomes unnecessary.
In order to make the Vdc detection value of DB unit the same as the Vdc detection value of an inverter,
adjustment of a Vdc display gain and Vdc display offset becomes unnecessary.
Note) Set up the power supply voltage system of DB unit in accordance with the power supply voltage
system of an inverter. In a mistaken setup, a Vdc display will be unusual. Refer to "5.4.3F20 (Power
supply voltage selection and Master/Slave selection and Station number set-up mode)" for a setup
of a power supply voltage system.
○
Starting voltage of DB operation is set automatically.
The preset value (F-00: built-in DB operation level) of an inverter is automatically set to
S
tarting voltage of
DB operation of DB unit. Refer to the instructions manual of VF66 series inverter for the preset value of
VF66 series inverter.
Note) At the time of communication option substrate use, the setting range of Starting voltage of DB
operation becomes narrow. (It is restricted to the setting range of an inverter.)
Table 7.1 Set-up range of DB operation starting voltage
