There are two different methods by which parameters in the
MASTERDRIVES can be read or written via the CAN bus.
♦ One option involves utilizing the complete PKW channel (parameter
identifier value) with object 4001h. To do this, however, you must be
familiar with the parameter editing principles of the
MASTERDRIVES.
♦ A simpler parameterization interface is provided to facilitate
assignment of the MASTERDRIVES parameters via the CBC with
SDO tasks. This interface only allows data to be written to the
EEPROM. The number for the parameter to be edited must be
identified in the MASTERDRIVES parameter list. 5000h must be
added to this parameter number and the product is then the object
number which can be read or written. The parameter index is
entered in the SDO object index.
An SDO write task must be sent from the master to the
MASTERDRIVES specifying the data type, subindex and value.
The object number and subindex must be specified in an object read
task. The response is sent automatically by the CBC.
Object 4001 (Parameter download)
h
Object with which parameters can be edited via an SDO task.
Since most of the parameters in MASTERDRIVES are not converted to
CANopen objects, it is possible to gain read or write access via
CANopen to all parameters with an SDO task using manufacturer-
specific object 4001h.
♦ Subindex 01
The parameter number, task identifier and index are entered in
subindex 01. These values are then sent by the master with a write
task.
The Page Select bit must be set to write parameters higher than
1999. The Page Select bit is bit 15 of the 2
