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 drive controller is provided with three parameter sets:
ƒ Current parameter set
This parameter set is stored in the volatile memory (RAM) of the drive controller. It can
be read or written to as desired with the Small Drive Control parameterisation program
or via the CAN bus. When switching on the drive controller, the application parameter
set is copied into the current parameter set.
ƒ Default parameter set
This parameter set is the unchangeable parameter set of the drive controller which is
preset by default. By writing into the CANopen object 1011_01h
(restore_all_default_parameters), the default parameter set can be copied into the
current parameter set . This copying process is only possible if the power stage is
switched off.
ƒ Application parameter set
The current parameter set can be saved in the non−volatile flash memory. The saving
process is initiated by a write access to the CANopen object 1010_01h
(save_all_parameters). When the drive controller is switched on, the application
parameter set is automatically copied into the current parameter set.
The following diagram illustrates the connections between the different parameter sets.
