You can choose between two different parameter set management variants:
1. The parameter set is created by using the »fluxx« parameterisation program and
transferred to the individual controllers. In this case, you only have to set the objects
which can only be accessed via CANopen via the CAN bus.
The disadvantage of this variant is that the parameterisation software is always
required whena newcontrolleris commissioned orincaseofrepairs (whenexchanging
the controller). Therefore, this variant is only useful when only one controller is used.
2. This variant is based on the fact that in most application-specific parameter sets
only a few parameters differ from the default parameter set. Therefore, the current
parameter set can be recreated via the CAN bus after every switch on of the system.
For this, the higher-level control loads the default parameter set (call of CANopen
object 1011_01h restore_all_default_parameters) first. After this, only the objects
that are different are transferred. This takes less than 1 second per controller. Of
advantage is that this method can also be used for controllers which have not been
parameterised yet so that the commissioning of new systems and exchange of
individual controllers is easy without requiring the parameterisation software.

Note!
We recommend to use variant 2. Please observe that it is not possible to set all
parameters via the CAN. If other parameters have to be set, the first variant
must be used.

Stop!
Uncontrolled motor rotation
A wrong parameter set can lead to an uncontrolled rotation of the motor.
Possible consequences:
ƒ
This can cause damage to material.
Protective measures:
ƒ Before switching on the power stage, please ensure that the controller really
contains the required parameter set.
