This parameter cannot be changed while the motor is running.
The standard speed open-loop mode in parameter 1-00 Configuration Mode is extended with a wobble function. In this parameter, it
is possible to select which method to be used for the wobbler. Set the parameters as absolute values (direct frequencies) or as rela-
tive values (percentage of other parameter). Set the wobble cycle time as an absolute value or as independent up and down times.
When using an absolute cycle time, the up and down times are configured through the wobble ratio.

The delta frequency determines the magnitude of the wobble frequency. The delta frequency is superimposed on the center fre-
quency. Parameter 30-01 Wobble Delta Frequency [Hz] contains both the positive and negative delta frequency. The setting of param-
eter 30-01 Wobble Delta Frequency [Hz] must thus not exceed the setting of the center frequency. The initial ramp-up time from
standstill until the wobble sequence runs is determined in parameter group 3-1* References.
