Note:
•
The nameplate must be visible at all times.
•
The nameplate is not permitted to be removed from the motor.
4.1.1 Embedded parameter chip
All relevant mechanical and electrical information and data is stored in the EnDat encoder used for B&R motors. This
means that the user does not have to configure settings on the servo drive. As soon as the encoder is connected
to the servo drive and the power supply to the electronics is switched on, the motor is automatically identified.
The motor sends its nominal parameters and limit parameters to the servo drive. The drive then automatically
determines the current limits and current control parameters required for optimal control of the motor. The only
things that the user has to optimize are the speed and position controllers. Support for this is provided by the
integrated commissioning environment of B&R Automation Studio
TM
.
In addition to assistance during commissioning, routine service work is also simplified, and motors can be replaced
without having to take extra time to set parameters.
