Optimising The Control Mode - Lenze L-force HighLine C 8400 Series Reference Manual

Optimising the control mode

The "optimisation steps" given in the table below serve to further optimise the control
behaviour of the sensorless control for synchronous motors and adjust it to the concrete
application.
 Detailed information on the individual steps can be found in the following
subchapters.
Generally, the following optimisation steps are recommended:
Optimisation steps
1. Optimise current
• The current controller should always be optimised if a motor of a third-party manufacturer with
unknown motor data is used!
2. Optimise speed
• The setting of the speed controller must be adapted depending on the mechanical path.
3. Optimise response to setpoint changes and determine mass
• For an optimal reference behaviour, the total moment of inertia can be used to make a feedforward
control of the speed setpoint.

Note!
Current setpoint filter (band-stop filter) / jerk limitation
The use of the functions is only recommended in exceptional cases.
The functions are described in the
