PARAMETERS: DEFINITION, STORAGE, AND ACCESS
6.1
INTRODUCTION TO PARAMETERS
Drive structures its parameters into two main categories: basic function parameters, and monitoring function
parameters. Each category is divided in different groups, and each group contains multiple parameters with a
related functionality.
Rectifier parameters:
MD800 rectifier
Basic function
parameters
Group F
RW F0, F1, F4, F5, F7, FA, FD, FF, FP
Group A
RW A0, A1, A3, AC, AE, AF
Monitoring
function
parameters
Status data
RO
U0,U2,U3,U4
Inverter parameters:
MD800 inverter
Basic function
parameters
Group F
RW F0, F1, F2, F3, F4, F5, F6, F7, F8, F9, FA, FB, FC, FD,
FE, FF, FP
Group A
RW A0, A1, A3, A5, A6, A9, AC, AD, AE, AF
Monitoring
function
parameters
Status data
RO
U0,U4,U5
Communication
control parameters
WO U3
To access to a parameter, you must indicate the group to which it belongs, and the ID of the parameter. See
the sample below:
Group Description

F0-16
AF - Process Data Address Mapping

00
AF-00
U0 - Monitoring Parameters

MEMORY AREAS AND COMMUNICATION ADDRESSES
Drive has RAM and EEPROM memory. All parameters are placed in both areas in the drive: RAM memory, and
EEPROM memory when the drive is power-off.
Parameter communication addresses must be used to perform a read-write and other operations of MD800.
Each parameter has its own EPPROM communication address to be accessed.
Furthermore, in the case of Basic Function Parameters, to avoid an intensive use of the
drive’s
EEPROM
memory, also they can be accessed to the RAM memory using a particular communication address.
6.2.1
EEPROM MEMORY ACCESS
The communication address to access to the EEPROM memory of the parameter, is represented in hexadecimal
format.
Following the same way as the parameter name, the communication address is made up of two parts:
•
The two most significant digits that represent the group to which the parameter belongs
•
And the two least significant digits that represent the ID of the parameter
