Figure 4.3.106 Upper/Lower offset operation
. When the stall prevention function is idle, perform the wobble operation in acceleration
and deceleration. However, it is actually performed in the process of the first
acceleration center frequency (19-00) when the wobble function is closed or the
command is deleted after a period of deceleration operation. However, you have to
consider selecting appropriate inverter capacity to match the system requirement and
the designed device.
. The limited wobble operation of this frequency range is determined by the upper limit
and lower limit of the inverter frequency. If (center frequency + amplitude) is greater
than the upper frequency limit, it will operate at the upper limit; if (center frequency -
Amplitude) is less than the lower frequency limit, it will operate at lower limit.
. In the wobble operation, all parameter values (19-00,19-07) can be modified.
