Rexroth provides advanced drive technology with a user-friendly interface.
For example, jogging was defined as an individual function. Rexroth has
provided this functionality (as also defined in the ProfiDrive) as bits in the
control word, and thus can now offer an interface that is easier to use.
The slave address is set on the plug-in module.
Status at Delivery:
The DKC3.3 address is set to 99 at delivery.
Slave addresses 1-99 (decimal) are supported.
Depending on the fieldbus type, however, the following limitations exist:
Profibus DP address: 2 ... 32 permitted
Note: Slave address 0 does not exist and cannot be used in
applications.
The address is read from the programming module when starting up the
DKC3.3, and it is used to set the parameters for the fieldbus.
Any change to the slave address takes effect only after startup of the
drive controller.
For each PROFIBUS-DP unit, a unit source file (*.GSD), in which the data
for the operation on the bus are stored, must be executed. This file is
required for each unit when configuring the bus master.
The unit source file for the ECODRIVE03 with FLP firmware is an ASCII
file named:
IN2_04eb.gsd
This unit source file also contains the following information, issued for this
configuration by the PNO (PROFIBUS user organization):
Ident Number = 04eb hex
Additionally, it is possible to set the transmission length. This is
dependent on the data to be transmitted. See Fig: 11-5.
The maximum data channel size is 32 bytes.
