5.1 Initial Configuration of the Performer
VSD sub-system
System components offered by the OEM, such as outdoor
units, indoor units/air handlers, evaporator modules or
furnaces are often manufactured in different locations and
first merged into a complete system at the end user’s site.
Furthermore, numerous combinations of such components
are feasible. Therefore it is extremely important to prepare
the components during manufacturing for a late merge in
the field.
Alternatively, the configuration of each individual
component can be made in the field. This can be done
with Danfoss Update tool or Modbus tool allowing
programming the drive, application controller and EEV
Controller via the serial communication interface (Modbus
RTU).
This functionality can also be incorporated in the OEM
Controller by establishing a protected service menu,
allowing accessing all Modbus registers.
Individual solutions can be worked out in cooperation with
the product support team.
5.2 Drive Setup
The variable speed drive including the embedded
application controller and the EEV Controller(s) can be
individually configured by setting various parameters
(Modbus registers). This manual is limited to the drive
parameters. For the application controller and the EEV
Controller(s), refer to the separately provided documen-
tation.
NOTE
Changing the setting of some registers requires re-booting
before the setting becomes effective. For details, refer to
the
Modbus RTU Communication Setup Manual
.
The timeouts and response times of Modbus messages to
and from the drive is in accordance with the Modbus
standard.
In the following chapters, the drive parameters are
described by the register number.
5.2.1 Drive Parameters
(Modbus Registers, node 162)
Register 40001-40010, PCA Bar Code (read only)
These registers (10) allow reading the bar code information
on the PCA, which is also found on the product identifi-
cation label on the drive chassis.
Register 40011-40020, Ordering code (read only)
These registers (10) allow reading the Danfoss ordering
code, which is also found on the product identification
label on the drive chassis, typically starting with 176L…..
Register 40021 and 40022, Operation Time Counter (read
only)
These registers allow reading the accumulated time the
drive has been powered. The value is given in seconds.
Register 40101-40110, AOC Software Version (read only)
These registers (10) allow reading the software version
number for the application oriented microprocessor.
Register 40111-40120, AOC Registers Version (read only)
These registers (10) allow reading the registers version
number for the application oriented microprocessor.
Register 40121 and 40122, Drive Status
These registers describe the exact operation condition of
the system in a 32 bit structure. See separate description
in
7 Fault Conditions, Messages and Causes
.
Register 40131, OEM Reset
Setting this register to logic “1” resets the drive to the
OEM defaults (configuration defaults set by the OEM in
production) stored in the EEPROM.
Register 40132, Danfoss Reset
Setting this register to logic “1” resets the drive to the
Danfoss defaults (factory defaults as listed in this manual
and Modbus register map files)
Register 40133, Overwrite Defaults
Setting this register to logic “1” allows overwriting the
factory defaults. This should only be done with assistance
from Danfoss.
NOTE
Do not set registers 40132 and 40133 to logic “1” at the
same time.
