5.7.2.1 Parameterising the encoder/feedback system
Required settings:
1. Parameterise the function of the digital inputs 1 and 2 as the encoder input in C00115
.
2. Set the encoder increments in C00420/1
.
3. Select the speed sensor in C00495
.
4. Adapt the filter time of the actual speed filter in C00497
.
5. In the case of encoders with a very low resolution (number of increments < 120
increments):
change the encoder evaluation procedure in C00496
if necessary.
5.7.3 Optimise control behaviour
The "optimisation steps" given in the table below serve to further optimise the control
behaviour of the servo control 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:
Special cases may require further optimisation steps:
 Tip!
In order to traverse a typical speed profile for optimisation of motor control, you
can also use the basic function "Manual jog
" with appropriately adapted manual
jog parameters if this basic function is supported by the selected technology
application.

Optimisation steps
1. Optimise current controller
. ( 153)
• The current controller should always be optimised if a motor of a third-party manufacturer with
unknown motor data is used!
2. Optimise speed controller
. ( 154)
• The setting of the speed controller must be adapted depending on the mechanical path.
3. Optimise response to setpoint changes and determine mass inertia
. ( 158)
• For an optimal reference behaviour, the total moment of inertia can be used to make a feedforward
control of the speed setpoint.
Optimisation steps
1. Setting the current setpoint filter (band-stop filter)
. ( 160)
• In order to suppress or damp (mechanical) resonant frequencies, a current setpoint filter is integrated in
the speed control loop which is switched off in the default setting but can be parameterised accordingly,
if required.
Then readjust the speed controller: Optimise speed controller
. ( 154)
2. Adapting the max. acceleration change (jerk limitation)
. ( 161)
3. Optimising the behaviour in the field weakening range
. ( 162)
