There are two possible variants for the parameter set management:
1. The parameter set is created with the Small Drive Control (SDC) parameterisation
program and transferred to the different drive controllers. When this method is
used, only the objects which can solely be accessed via CANopen have to be set via
the CAN bus.
The disadvantage of this method is that the parameterisation software is required for
the commissioning of a new drive controller or in the event of a repair being necessary
(replacement of the drive controller). Therefore this method only makes sense for
single controllers.
2. This variant is based on the fact that most application−specific parameter sets differ
from the default parameter set in only a few parameters. Due to this, it is possible to
recreate the current parameter set via the CAN bus after every switching on of the
system.
For this purpose, the higher−level control first loads the default parameter set (calling
of the CANopen object 1011_01h restore_all_default_parameters). Then only the
differing objects are transferred. The whole process takes less than 1 second per drive
controller. The advantage of this method is that it also functions for unparameterised
drive controllers, so that the commissioning of new systems or the replacement of
individual controllers does not cause any problems and the parameterisation software
is not needed.

Note!
We recommend to use the second variant. Please observe that not all
parameters can be set via CAN. If the setting of these parameters is required,
the first variant has to be used.

Stop!
Uncontrolled rotation of the motor
An incorrect parameter set can cause uncontrolled rotation of the motor.
Possible consequences:
ƒ This may result in property damage.
Protective measures:
ƒ Before the initial switch−on of the power stage, ensure that the drive
controller really contains the correct parameter set.
