7 Parameter setting
Before the drive controller can perform the required task (torque or speed control or
positioning), several controller parameters have to be adapted to the motor used and to
the specific application. For this purpose you should keep to the sequence given in the
following chapters.
These chapters first explain the parameterisation and then the device control and the use
of the different operating modes.
7.1 Loading and saving of parameter sets
7.1.1 Overview
The controller has three parameter sets:
ƒ Current parameter set
The current parameter set is stored in the volatile controller memory (RAM). It can be
written and read as you like by using the »fluxx« parameterisation program or via the
CAN bus. When the controller is switched on, the application parameter set is copied
to the current parameter set.
ƒ Default parameter set
The default controller parameter set is default set and cannot be changed. By writing
to the CANopen object 1011_01h (restore_all_default_parameters), the default
parameter set can be copied to the current parameter set. Copying is only possible
when the power stage is switched off.
ƒ
Application parameter set
The current parameter set can be saved in the non-volatile flash memory. Saving is
activated by a write access to the CANopen object 1010_01h (save_all_parameters).
When the controller is switched on, the application parameter set is automatically
copied to the current parameter set.
The following chart shows the connections between the individual parameter sets.
